The Gospel of John — The Spiritual Gospel and Its Journey to Canon

Part of the series: The New Testament Canon—How 27 Books Survived the Ancient Gauntlet

The Gospel of John is the strangest of the four, and the highest. It opens not with a genealogy or a manger but in eternity — “In the beginning was the Word” — and it never really comes back down. There are no parables in John, no exorcisms, no transfiguration, no agony in the garden, and no institution of the Eucharist at the Last Supper. In their place stand long, luminous discourses, seven great signs, the seven “I am” sayings, and a Jesus who says openly what the other three Gospels only imply: “Before Abraham came to be, I AM.”⁠¹ Clement of Alexandria, near the end of the second century, gave the book the name it has carried ever since. The other evangelists had recorded the outward facts; John, “inspired by the Spirit, composed a spiritual Gospel.”⁠²

That exalted character is the source of the Fourth Gospel’s peculiar history. Precisely because John flew so high, he was the evangelist the second-century heretics loved best. The first commentary ever written on any book of the New Testament was a commentary on John — and its author was a Gnostic. The Valentinians read the Prologue as a coded map of their divine hierarchy; the Nag Hammadi library breathes Johannine air. And precisely because the heretics had colonized John so thoroughly, a small band of the orthodox grew nervous about him. A group in Asia Minor rejected the Gospel and the Book of Revelation together, pinning both on the heretic Cerinthus — a group a later bishop mocked with a name that punned on their refusal of the divine Logos: the Alogoi, “those without the Word.”⁠³

And yet John never seriously wavered. By the time Eusebius took stock of the canon in the early fourth century, the Fourth Gospel stood at the head of the “acknowledged” books, received without dispute in every church under heaven.⁠⁴ This post traces how that happened: what makes John so different from Matthew, Mark, and Luke; who the tradition says wrote it, and why modern scholars argue about which John it was; when and where it was composed, and how a single scrap of papyrus settled one old debate; and how the Gospel the Gnostics prized became, for the Catholic Church, the eagle among the evangelists — the book read at the deathbed of the Church’s Lenten catechumens and proclaimed from the ambo every Good Friday.

The “spiritual Gospel”

Anyone who reads Matthew, Mark, and Luke and then turns to John feels the change of altitude at once. The first three Gospels — the Synoptics, so called because they can be set side by side and “seen together” — share a common outline, a common stock of episodes, and a Jesus who teaches in short, earthy parables and casts out demons across Galilee. John shares almost none of it. He has no parables in the Synoptic sense, no exorcisms, no transfiguration, no Sermon on the Mount, no Lord’s Prayer, and no account of the bread and cup at the Last Supper. What he has instead is a Jesus who speaks in long, spiraling discourses about light and darkness, bread and water, the Father and the Son, and who works not “mighty deeds” but “signs” that reveal his glory.

Clement of Alexandria, writing around the year 200 and preserved for us by Eusebius, explained the difference with a theory of composition. The Gospels with the genealogies, Clement said, were written first; Mark took down Peter’s preaching; “but, last of all, John, perceiving that the external facts had been made plain in the Gospel, being urged by his friends, and inspired by the Spirit, composed a spiritual Gospel.”⁠⁵ Whatever one makes of Clement’s chronology, his instinct was sound. John is not trying to do again what the Synoptics had done. He assumes the outward story and presses past it to its meaning, and he tells the reader as much at the end: “these are written that you may come to believe that Jesus is the Messiah, the Son of God, and that through this belief you may have life in his name.”⁠⁶

What John leaves out, and what he puts in

The omissions are striking, but the additions are the point. Where the Synoptics open with a genealogy (Matthew), a prophetic herald (Mark), or an infancy narrative (Luke), John opens outside time altogether, with a hymn to the pre-existent Word:

In the beginning was the Word, and the Word was with God, and the Word was God… And the Word became flesh and made his dwelling among us, and we saw his glory, the glory as of the Father’s only-begotten Son, full of grace and truth.⁠⁷

No other Gospel makes so direct a claim about who Jesus is. The theme, once sounded, never fades. John organizes the public ministry around seven “signs” — the water made wine at Cana, the healing of the official’s son, the cure of the paralytic at Bethesda, the feeding of the five thousand, the walking on the water, the man born blind, and the raising of Lazarus — each one a miracle that is also a revelation.⁠⁸ And running through the discourses are the seven great “I am” sayings, in which Jesus takes the divine name of Exodus and fills it with an image: I am the bread of life, the light of the world, the gate for the sheep, the good shepherd, the resurrection and the life, the way and the truth and the life, the true vine.⁠⁹ To these John adds the absolute “I am” sayings, without predicate, that scandalized Jesus’ hearers because they heard in them a claim to deity: “before Abraham came to be, I AM.”⁠¹⁰ This is the highest explicit Christology in the New Testament, and it reaches its climax when the doubting Thomas, confronted with the risen Lord, can only say, “My Lord and my God.”⁠¹¹

Even the Last Supper is transformed. Where the Synoptics narrate the institution of the Eucharist over bread and wine, John gives instead the washing of the disciples’ feet and four chapters of farewell discourse, and he locates his great Eucharistic teaching earlier, in the Bread of Life discourse at Capernaum: “I am the living bread that came down from heaven.” The Catechism of the Catholic Church notes the arrangement without embarrassment: the institution of the Eucharist comes to us from the Synoptics and from Paul, while “St. John, for his part, reports the words of Jesus in the synagogue of Capernaum that prepare for the institution of the Eucharist.”⁠¹² The four Gospels, on the Catholic reading, are not rivals but a chord.

Three Passovers and the day the Lamb died

The differences are not only of tone; some are matters of hard chronology, and honesty requires naming them. Two stand out. First, John places the cleansing of the Temple at the very beginning of Jesus’ ministry, in chapter 2, where the Synoptics place it in the final week.⁠¹³ Second, and more consequentially, John’s Jesus goes up to Jerusalem for three distinct Passovers, which implies a public ministry of roughly three years, whereas the Synoptic outline can be read as a single year culminating in one final Passover.⁠¹⁴ It is from John, not the Synoptics, that the Church derives the familiar “three-year ministry.”

The sharpest difference concerns the day Jesus died. In the Synoptics, the Last Supper is a Passover meal, which places the crucifixion on the feast day itself. In John, the meal precedes the feast: on the morning of the trial the priests will not enter Pilate’s headquarters “in order not to be defiled so that they could eat the Passover,” and Jesus is condemned at noon on “preparation day for Passover” — the very hour, John’s readers would know, at which the Passover lambs began to be slaughtered in the Temple.⁠¹⁵ The theology is unmistakable and deliberate: John has arranged his account so that Jesus dies as the true Passover Lamb, the one of whom “not a bone shall be broken,” exactly when the lambs are dying. Whether the difference from the Synoptics is a matter of a different calendar, of a deliberate theological adjustment, or of John’s greater precision, is a question scholars such as Raymond Brown have weighed at length and left genuinely open.⁠¹⁶ A responsible account does not paper the difference over. It is one of the places where the fourfold Gospel asks to be read as four witnesses, not one flattened harmony.

Who wrote the Fourth Gospel?

Like the other three, John is formally anonymous. The author never gives his name. What the Gospel offers instead is a shadowy figure who appears only in its second half — “the disciple whom Jesus loved,” who reclines next to Jesus at the supper, stands beneath the cross, outruns Peter to the empty tomb, and recognizes the risen Lord on the shore of Galilee. At the very end, an editorial note identifies this Beloved Disciple as the source of the book and vouches for him in a curious first-person plural: this is the disciple who has written these things, “and we know that his testimony is true.”⁠¹⁷ Whoever the “we” are, they are not quite the same voice as the disciple they commend. The Gospel’s own last words, in other words, already point to a community standing behind the witness — and that is where every modern theory of authorship begins.

The witness of the second century

The external tradition, by contrast, is early and remarkably confident. The first surviving writer to name John as the author of the Gospel and to quote its opening line is Theophilus of Antioch, around 180: the inspired men taught us, he writes, “one of whom, John, says, ‘In the beginning was the Word, and the Word was with God.’”⁠¹⁸ In the same years Irenaeus of Lyons, who had known Polycarp of Smyrna and so stood only one link from the apostolic age, states the tradition in its classic form: “Afterwards, John, the disciple of the Lord, who also had leaned upon His breast, did himself publish a Gospel during his residence at Ephesus in Asia.”⁠¹⁹ Irenaeus adds a motive: John wrote to refute the errors of Cerinthus and the Nicolaitans, the proto-Gnostics who divided the man Jesus from the heavenly Christ.⁠²⁰

The Muratorian Fragment, an early canon list usually dated to the later second century, tells the same story with a legend attached: when his fellow disciples and bishops urged John to write, he asked them to fast with him three days, and on that night it was revealed to the apostle Andrew that John should write everything down in his own name with the others’ review.⁠²¹ And Polycrates, bishop of Ephesus around 190, defending his city’s liturgical customs in a letter to Pope Victor, names among the “great lights” buried in Asia “John, who was both a witness and a teacher, who reclined upon the bosom of the Lord, and being a priest wore the sacerdotal plate. He also sleeps at Ephesus.”⁠²² That last detail — John as a priest wearing the high-priestly petalon — is a genuine puzzle no one has fully explained, and it is one of several threads that complicate any simple identification of the evangelist with the Galilean fisherman.

The problem of the two Johns

The complication has a name, and it comes from the earliest source of all. Papias of Hierapolis, writing perhaps around 110, described how he collected the sayings of the apostles from those who had known them — and in doing so he mentioned “John” twice. He inquired, he says, what Andrew or Peter or Philip or Thomas or James “or John or Matthew” had said, and then, in a separate clause, what “Aristion and the presbyter John, the disciples of the Lord, say.”⁠²³ Eusebius, reading this passage in the fourth century, drew the inference that has haunted Johannine scholarship ever since: Papias names two different men called John, one an apostle and one “the presbyter,” and “there were two tombs in Ephesus, each of which, even to the present day, is called John’s.”⁠²⁴ Eusebius, who disliked the Book of Revelation, was glad to assign that book to the second John and keep the apostle’s name clean; but whatever his motives, the two-Johns problem is real. The tradition that fixed the Gospel at Ephesus may have known more than one candidate there.

The modern debate

Modern scholarship has taken these ancient threads in several directions, and it is worth laying the options out fairly rather than pretending the question is closed. The traditional view — that the author is John the son of Zebedee, the apostle, identical with the Beloved Disciple — still has able defenders, among them Leon Morris, D. A. Carson, and Craig Blomberg, who argue that the Gospel’s intimate knowledge of Palestine and of Jesus’ inner circle points most naturally to an eyewitness apostle.⁠²⁵ Against them stands the dominant twentieth-century reconstruction associated above all with the great Catholic scholar Raymond Brown, who came to see the Gospel as the deposit of a distinct “Johannine community” gathered around the memory of the Beloved Disciple, its final text the work of an evangelist and a redactor rather than of the apostle’s own hand. Brown’s own view migrated over his career, and by the end he was inclined to think the Beloved Disciple an unnamed minor disciple of Jesus rather than John of Zebedee.⁠²⁶ A third position, revived powerfully by Martin Hengel and Richard Bauckham, seizes on Papias’s “presbyter John” and identifies him as the Beloved Disciple and author — a real eyewitness, though not one of the Twelve.⁠²⁷ The older history-of-religions reading of Rudolf Bultmann, which dissolved the Gospel into hypothetical sources and read it against a Gnostic redeemer-myth, has largely collapsed in its particulars, though its source-critical instincts still echo.⁠²⁸

The honest summary is that the external tradition is early, consistent, and specific in naming John of Ephesus, while the internal evidence, together with Papias’s stubborn ambiguity, keeps the precise identity open. For the Catholic reader, nothing essential hangs on the verdict. The Church receives the Gospel as apostolic in authority and inspired in every word, and the Second Vatican Council’s Dei Verbum, which affirms the apostolic origin and historical character of the four Gospels while endorsing the careful use of critical method, leaves believers free to weigh the historical question on its merits.⁠²⁹ The most defensible conclusion is a modest one: the Fourth Gospel preserves the authoritative testimony of a Beloved Disciple in the Johannine circle of Asia Minor — very plausibly a John, whether the apostle or the elder — and reached its final form through the community that vouches for him in its closing lines.

When and where John was written

On the date, the Catholic and mainstream scholarly consensus agree, and they agree with the plain sense of the evidence. The Gospel was written toward the end of the first century; the New American Bible’s introduction says it was “probably written in the 90s of the first century,” with its final editing falling between about A.D. 90 and 100.⁠³⁰ A vigorous minority, led a half-century ago by the Anglican bishop John A. T. Robinson, has argued for a date before the fall of Jerusalem in 70; that view remains a minority report, but it is a serious one.⁠³¹ At the opposite extreme, the nineteenth-century Tübingen school of F. C. Baur once dated John as late as around 160 to 170, reading it as a second-century product of Gnostic-tinged theology rather than an apostolic memoir.⁠³² That late dating was, for a time, the great weapon of critical skepticism about the Gospel’s origin — and it was destroyed by a scrap of papyrus the size of a credit card.

P52 and the end of the late-dating theory

In 1920 the papyrologist Bernard Grenfell acquired, among a lot of fragments from Egypt, a small piece of a codex leaf that lay unstudied for years until C. H. Roberts recognized what it was and published it in 1935. The fragment — catalogued as Rylands Greek Papyrus 457, and known to scholars as P52 — carries a few verses of John 18 on both sides: Pilate’s interrogation of Jesus on one face, and the exchange about truth and kingship on the other.⁠³³ It is generally reckoned the oldest surviving fragment of any book of the New Testament. Roberts, comparing its handwriting to dated documents, assigned it to the first half of the second century, and the popular literature promptly rounded that to “about 125.”

Here a careful writer must be scrupulous, because the fragment has been made to prove more than it can. Paleographic dating — dating a hand by its resemblance to other hands — is not precise, and in an influential 2005 study Brent Nongbri showed that the honest range for P52 must be widened to include the later second and even the early third century; the frequently cited bracket of “125 to 175” is in fact the proposal of a later pair of scholars, not Roberts’s own figure, and even that is a range, not a date.⁠³⁴ What P52 cannot do is pin the composition of John to 125. What it can do — and this is decisive — is sink the Tübingen theory: a copy of John circulating in provincial Egypt by the middle of the second century is impossible to reconcile with a composition date of 160 to 170, since the text needs time to be written, copied, and carried up the Nile. Even on the most cautious reading of the fragment, John is a first-century book.

The place of writing is far less certain than the date. The ancient tradition is unanimous for Ephesus, on the authority of Irenaeus and Polycrates, and Ephesus remains the leading candidate. But many scholars favor Syria, perhaps Antioch, and a few have proposed Alexandria, pointing to the Egyptian provenance of the earliest papyri; the New American Bible’s introduction lists all three without deciding among them.⁠³⁵ On this, unlike the date, the evidence simply runs out.

A Gospel that grew

One of the quiet lessons of reading John closely is that the book took shape in stages, and it does not hide the seams. The Gospel appears to reach its natural conclusion at the end of chapter 20: “Now Jesus did many other signs… But these are written that you may come to believe.”⁠³⁶ Then chapter 21 opens a fresh scene in Galilee, with the miraculous catch of fish, the rehabilitation of Peter, and a second, plainly editorial ending. The near-universal scholarly judgment is that chapter 21 is an epilogue added after the main Gospel was complete — though added early enough that it appears in every surviving manuscript, which is why the Church receives it, like the rest, as inspired Scripture.⁠³⁷

There are smaller seams within the book as well. At the close of the farewell discourse Jesus says, “Get up, let us go,” as though the company is about to leave the upper room — and then three more chapters of discourse follow before anyone actually moves.⁠³⁸ The New American Bible’s own introduction acknowledges such “inconsistencies” and concludes, with most scholars, that they were “probably produced by subsequent editing in which homogeneous materials were added to a shorter original.”⁠³⁹ For a Catholic reader this is not a threat but a description of how an inspired book was in fact composed: the Holy Spirit worked through an author, a community, and an editor, and the whole canonical text, seams and epilogue alike, is the word of God.

The gem in the manuscripts: the woman caught in adultery

Nowhere is this clearer than in the most beloved story in the Gospel — and one of the great open secrets of biblical scholarship. The account of the woman caught in adultery, whom Jesus refuses to condemn while her accusers slink away (“Let the one among you who is without sin be the first to throw a stone”), is not part of the original Gospel of John. It is absent from all the earliest and best manuscripts — the great papyri P66 and P75, and the fourth-century codices Sinaiticus and Vaticanus — and no Greek Father comments on it until the twelfth century, though the Latin West knew and cherished it much earlier. It even “floats,” appearing at different places in different manuscripts, sometimes after John 7:52, sometimes at the end of the Gospel, sometimes over in Luke.⁠⁴⁰ The New American Bible states the situation plainly in its note: the passage is “a later insertion here, missing from all early Greek manuscripts,” a Western text with many non-Johannine features — and then, in the same breath, “The Catholic Church accepts this passage as canonical scripture.”⁠⁴¹

This is worth pausing over, because it is exactly the kind of fact that is thought to embarrass the Church and does not. The Council of Trent, defining the canon in 1546, received the books of Scripture “with all their parts” as they stood in the old Latin Vulgate — and the Vulgate contained this story.⁠⁴² The Catholic doctrine of inspiration was never a claim about the autograph manuscript of a lone author; it is a claim about the canonical text the Church received and hands on. That a passage entered the tradition later, and that we can see it happening in the manuscripts, changes nothing about its standing as Scripture. It is a striking case, and an instructive one, of how the Church’s confidence rests not on a reconstructed original but on the living text she has always read.

The Gospel the heretics loved

Here we reach the strangest chapter of John’s story, and the one that makes it a canon-series subject rather than a mere entry in a Gospel harmony. For most of the second century, the Fourth Gospel’s most enthusiastic readers were not the orthodox but the Gnostics. The earliest known commentary on any book of the New Testament — the first sustained, verse-by-verse exposition of a Christian Scripture that we can name — was written on John, and its author was the Valentinian teacher Heracleon, active around the 170s. We know it because Origen, refuting Heracleon two generations later in his own vast Commentary on John, quoted him some forty-eight times.⁠⁴³ The Gnostics did not merely tolerate John; they made him their theologian.

They did so because the Prologue, read a certain way, could be made to speak their language. Ptolemy, another Valentinian, took the opening verses — God, the Beginning, the Word, and the sequence of divine names — and read them as a coded revelation of the aeons, the emanations of the divine fullness in the Valentinian system. Irenaeus preserves the exegesis in order to demolish it: John, the Valentinians claimed, “indicated the first Ogdoad” in his Prologue, distinguishing Father, Grace, Only-Begotten, and Truth.⁠⁴⁴ The Nag Hammadi text called the Gospel of Truth, associated with the Valentinian school, is steeped in the same Johannine vocabulary of Word and Life and Light. John’s very sublimity — the height that made him the “spiritual Gospel” — made him the most useful of the four to those who wanted to spiritualize Christianity out of the flesh entirely.

The Alogi and the orthodox backlash

The reaction was predictable, and it is one of the most curious episodes in the history of the canon. If the heretics loved John so much, a few of the orthodox concluded, perhaps there was something wrong with John. A group in Asia Minor in the later second century rejected the Fourth Gospel outright, and rejected the Book of Revelation with it, and attributed both not to the apostle but to the heretic Cerinthus — the very Cerinthus whom Irenaeus said John had written to refute.⁠⁴⁵ Two centuries later the bishop Epiphanius of Salamis, cataloguing every heresy he could find, mocked this group with a coined nickname that has stuck: the Alogoi, a pun meaning at once “those without the Logos” — the Word they refused to receive — and simply “the irrational ones.”⁠⁴⁶

Irenaeus already knew of such people, though he did not name them. In the same book where he defends the fourfold Gospel he describes those who “do not admit that aspect” of the message presented by John — the promise of the Paraclete, the Spirit — and who therefore “set aside at once both the Gospel and the prophetic Spirit.”⁠⁴⁷ A shadowy parallel figure in the West is Gaius, a Roman presbyter of the early third century, who is reported to have impugned the Johannine writings; but the evidence about Gaius is genuinely murky. What Eusebius actually preserves is Gaius attacking the “revelations” of Cerinthus, which most read as an assault on the Book of Revelation rather than the Gospel, and the claim that he rejected the Gospel too rests on a late and disputed Syriac report of a lost work by Hippolytus.⁠⁴⁸ The orthodox suspicion of John, in other words, was real but small — a minority tremor, not a schism.

Irenaeus and the four pillars

What overwhelmed the tremor was Irenaeus. In the third book of Against Heresies, around 180, he gave the Church the argument that fixed the number of the Gospels at four — no more, no fewer — and it is one of the most famous, and most easily misremembered, passages in patristic literature. “It is not possible,” he wrote, “that the Gospels can be either more or fewer in number than they are. For, since there are four zones of the world… and four principal winds,” the Church, spread over all the earth, must rest on four pillars.⁠⁴⁹ He then matched each Gospel to one of the four living creatures of Ezekiel and Revelation — and this is where nearly everyone gets Irenaeus wrong. In his scheme, John is not the eagle. Irenaeus assigns the lion to John, “symbolizing his effectual working, his leadership, and royal power,” because John relates Christ’s “original, effectual, and glorious generation from the Father”; the eagle he gives to Mark, for the prophetic Spirit descending on the Church.⁠⁵⁰

The pairing everyone remembers — John the eagle, Mark the lion — is not Irenaeus’s but Jerome’s. It was Jerome, writing his commentary on Matthew around 398, who arranged the creatures in the order that became standard in Western art: the man for Matthew, the lion for Mark, the ox for Luke, and the eagle, soaring highest, for John.⁠⁵¹ Augustine offered yet another arrangement, and it is Augustine who gave the eagle its most memorable expression. In his Tractates on John he wrote that the evangelist, “not undeservedly in respect of his spiritual understanding compared to the eagle, has elevated his preaching higher and far more sublimely than the other three,” soaring above the clouds and even above the angels to reach the Word by whom all things were made.⁠⁵² The bird that stands over John’s shoulder in a thousand stained-glass windows is Jerome’s gift, deepened by Augustine, not the assignment of the Church’s first great defender of the four.

Firm canonical status

For all the Gnostic enthusiasm and the small orthodox recoil, John’s place in the canon was, in the end, never in serious doubt. Eusebius, drawing up his careful inventory of the New Testament writings in the early fourth century, put the Gospel of John at the very head of the “acknowledged” books — the homologoumena, received everywhere and questioned nowhere. His Gospel, Eusebius wrote, “is known to all the churches under heaven,” and among the writings of John “not only his Gospel, but also the former of his epistles, has been accepted without dispute both now and in ancient times.”⁠⁵³ John appears in every early canon list without hesitation: in Irenaeus’s fourfold argument, in the Muratorian Fragment, in Origen, in Athanasius’s Festal Letter of 367, and in the African councils of Hippo (393) and Carthage (397). Unlike the Book of Revelation, which shared John’s name and endured centuries of Eastern doubt, the Fourth Gospel never faced a regional rejection that stuck.⁠⁵⁴

A word is in order about how scholars now tell this story, because the older textbooks overstated it. An earlier generation of critics, following J. N. Sanders and T. W. Manson, spoke of an “orthodox Johannophobia” — the theory that the mainstream Church shied away from John for most of the second century precisely because the heretics had seized it, and embraced it only when Irenaeus made it safe. That picture has been powerfully challenged, most thoroughly by Charles E. Hill, who argued that orthodox writers in fact used John early and widely, and that the “phobia” is largely a modern construction.⁠⁵⁵ The fair verdict lies between the extremes: the Gnostic love and the Alogi’s fear were both real, but so was the steady orthodox use of John from the beginning. The Church’s confidence in her fourth Gospel was tested; it was never broken.

The theology of the Word made flesh

To read John after tracing his troubled reception is to understand why he was worth fighting over. His theology is the deepest in the New Testament, and it begins where the Nicene Creed begins, with the eternal generation of the Son. The Prologue’s Logos — the Word who was “in the beginning,” who was “with God,” and who “was God” — draws on more than one stream: the creative word of Genesis, by which God speaks the world into being; the personified Wisdom of the Old Testament, present with God at creation; and, at the edges, the logos of Hellenistic philosophy, the rational principle that orders all things.⁠⁵⁶ John gathers these and does something none of them had done: he says the Word “became flesh.” The Catechism folds the verse directly into its doctrine of creation, quoting John that “all things were made through him,” and into its doctrine of the Incarnation, from which the Church takes the very word: “Taking up St. John’s expression, ‘The Word became flesh,’ the Church calls ‘Incarnation’ the fact that the Son of God assumed a human nature in order to accomplish our salvation in it.”⁠⁵⁷

The Gospel that follows is organized, on the framework standardized by Raymond Brown’s great commentary, into two movements. The Book of Signs (chapters 1 through 12) unfolds Jesus’ public ministry through the seven signs and the discourses that interpret them; the Book of Glory (chapters 13 through 20, with chapter 21 as epilogue) turns inward to the disciples, moving through the foot-washing, the farewell discourse, the Passion, and the Resurrection.⁠⁵⁸ Across both, John’s Christology stays at full altitude, and his eschatology takes a distinctive turn. C. H. Dodd famously called it a “realized” eschatology: in John, eternal life and judgment are not merely future events but present realities, entered now through faith — “whoever hears my word and believes… has passed from death to life.” The description is apt, provided one remembers that John also keeps the future hope of resurrection “on the last day,” so that his eschatology is better called both-and than simply realized.⁠⁵⁹ The farewell discourse adds what no other Gospel gives at such length: the promise of the Paraclete, the Advocate and Spirit of truth whom the Father will send in the Son’s name to abide with the Church.⁠⁶⁰

John and the Catholic faith

No Gospel has fed Catholic theology and worship more richly than John, and the debt runs from the highest doctrine to the ordinary rhythm of the liturgical year. The Church’s dogma of the Incarnation is stated in John’s words; her understanding of the Eucharist leans on the Bread of Life discourse of chapter 6; her image of Christ as the Good Shepherd who lays down his life for the sheep, and as the true vine in whom the branches abide, comes from John’s “I am” sayings. The Second Vatican Council’s Dei Verbum set the seal on how Catholics read all four Gospels, John included: the Church “has always and everywhere held… that the four Gospels are of apostolic origin,” and she “unhesitatingly asserts” their historical character, while recognizing that the evangelists wrote as theologians, “selecting some things, reducing others to a synthesis, explaining still others” for the good of the churches they served.⁠⁶¹ That last clause is precisely what lets a Catholic read John’s high discourses and distinctive chronology as inspired theology rather than as a problem to be explained away.

The liturgy loves John most of all. Alone among the evangelists, John is not assigned a “year” in the three-year Sunday cycle — Matthew has Year A, Mark Year B, Luke Year C — because John is read across all three, and above all in the holiest seasons. In Lent, the great baptismal Gospels that accompany the scrutinies of those preparing for Easter are all Johannine: the Samaritan woman at the well, who receives the living water; the man born blind, healed by the light of the world; and the raising of Lazarus, who hears the voice of the resurrection and the life.⁠⁶² On Good Friday, the Passion proclaimed in every Roman-rite church in the world is always John’s — his account of the trial, the crucifixion, and the pierced side from which blood and water flowed.⁠⁶³ And on Christmas Day itself, at the Mass during the day, the Gospel is not a nativity scene but the Prologue: “In the beginning was the Word… and the Word became flesh.” The Church ends the year’s greatest feast where John began his Gospel — in eternity, with the Word who was God. It is fitting that the Fathers gave this evangelist the eagle, and the East gave him a title it reserves for almost no one else: John the Theologian.

What we know and what remains open

Some things about the Fourth Gospel are as secure as anything in the study of the New Testament. It is the latest of the four, written toward the close of the first century; it is the most theologically ambitious, the one that states most plainly that Jesus is God; it grew in stages, with an epilogue and visible seams, and its most famous story entered the text later than the rest. It was the darling of the second-century Gnostics and the object of a small orthodox suspicion, and it emerged from both to stand unshaken among the four acknowledged Gospels. Its theology gave the Church the language of the Incarnation, and its scenes fill the holiest days of her calendar.

Other things remain genuinely open, and a careful writer leaves them open. Whether the Beloved Disciple was John the son of Zebedee, or the mysterious “presbyter John” of Ephesus, or an unnamed disciple whose community preserved his witness, rests on evidence that is early and consistent in its broad outline but ambiguous in its detail. The place of composition is uncertain; the precise process by which the Gospel reached its final form can only be reconstructed. On these questions the Catholic Church leaves the historical work to scholarship, holding fast only to what is not open: that whoever held the pen, the Church receives the Gospel of John as the inspired word of God — the book in which the Word who was in the beginning, through whom all things were made, is seen and heard and touched, full of grace and truth.

Frequently Asked Questions

Who wrote the Gospel of John?

The Gospel is formally anonymous; the author never names himself, identifying his source only as “the disciple whom Jesus loved.” From the late second century a consistent tradition — Theophilus of Antioch, Irenaeus, the Muratorian Fragment, and Polycrates of Ephesus — assigned it to John, who was said to have written at Ephesus. The difficulty is which John: an ambiguity in Papias, as read by Eusebius, points to both an apostle John and a separate “presbyter John” at Ephesus, and modern scholars divide among the apostle (Morris, Carson), an unnamed disciple whose Johannine community produced the Gospel (Raymond Brown), and the “presbyter John” as an eyewitness who was not one of the Twelve (Hengel, Bauckham). The Catholic Church receives the Gospel as apostolic and inspired and leaves the historical question to scholarship.

Why is the Gospel of John so different from Matthew, Mark, and Luke?

John shares almost none of the Synoptic outline. He has no parables, no exorcisms, no transfiguration, and no institution of the Eucharist at the Last Supper; in their place stand the cosmic Prologue, seven “signs,” long discourses, the seven “I am” sayings, and the highest explicit Christology in the New Testament. John also differs in chronology, placing the Temple cleansing at the start of the ministry, spreading that ministry over three Passovers, and dating the crucifixion to the eve of Passover, so that Jesus dies as the Passover lambs are slain. Clement of Alexandria called John the “spiritual Gospel” because it presses past the outward facts to their meaning. The Catholic Church reads the four Gospels as complementary witnesses rather than as a single flattened account.

Why did some in the early Church reject the Gospel of John?

Because the Gnostics loved it. The Valentinian Heracleon wrote the earliest known commentary on any New Testament book — a commentary on John — and Valentinians such as Ptolemy read the Prologue as a map of their own divine hierarchy. In reaction, a group in Asia Minor in the later second century rejected both John’s Gospel and the Book of Revelation and attributed them to the heretic Cerinthus; the fourth-century bishop Epiphanius mocked them as the “Alogi,” a pun on their refusal of the divine Word. The suspicion was real but small, and it was overwhelmed by Irenaeus’s argument for a fourfold Gospel. By Eusebius’s day John’s Gospel stood among the undisputed books.

What is the oldest manuscript of the Gospel of John?

The oldest surviving fragment of any New Testament text is a scrap of John known as P52 (Rylands Greek Papyrus 457), which preserves a few verses of John 18 on both sides. Its editor C. H. Roberts dated it in 1935 to the first half of the second century, often rounded to “about 125,” but paleographic dating is imprecise, and the honest range extends into the later second century (roughly 125–175). Even on the cautious dating, P52 disproves the old theory that John was composed as late as 160–170, since a copy was already circulating in Egypt by mid-century. Slightly later papyri, P66 (c. 200) and P75 (c. 175–225), preserve most of the Gospel.

Is the story of the woman caught in adultery really part of John’s Gospel?

Textually, no; canonically, yes. The account of the woman caught in adultery (John 7:53–8:11) is absent from the earliest and best manuscripts, including the papyri P66 and P75 and the codices Sinaiticus and Vaticanus, and no Greek Father comments on it until the twelfth century; in the manuscripts that do contain it, it even “floats” to different locations. It was known and loved in the Latin West much earlier and stood in Jerome’s Vulgate. The Catholic Church, which at the Council of Trent received the Scriptures “with all their parts” as found in the Vulgate, accepts the passage as canonical and inspired. Catholic inspiration is a claim about the received canonical text, not about a reconstructed original.

How does the Catholic Church use the Gospel of John today?

Extensively, and in the holiest seasons. John is not assigned a single “year” in the three-year Sunday lectionary but is read across all three, especially in Lent and Easter. The great baptismal Gospels of the Lenten scrutinies — the Samaritan woman (John 4), the man born blind (John 9), and the raising of Lazarus (John 11) — are all Johannine; the Passion proclaimed on Good Friday is always John’s (18:1–19:42); and the Gospel of the Christmas Mass during the day is John’s Prologue. The Catechism draws on John for its teaching on the Incarnation and the Eucharist, and the patristic tradition honored John as “the Theologian,” the eagle among the evangelists.

Footnotes

1. 1. John 8:58 (NABRE): “Amen, amen, I say to you, before Abraham came to be, I AM.” The New American Bible prints “I AM” in capitals to signal the allusion to the divine name of Exodus 3:14. See bible.usccb.org/bible/john/8.

2. 2. Clement of Alexandria, quoted in Eusebius, *Ecclesiastical History* 6.14.7 (NPNF, 2nd ser., vol. 1, trans. Arthur Cushman McGiffert): “But, last of all, John, perceiving that the external facts had been made plain in the Gospel, being urged by his friends, and inspired by the Spirit, composed a spiritual Gospel.” See newadvent.org/fathers/250106.htm.

3. 3. On the Alogi, see Epiphanius, *Panarion* 51, and note 46 below. The name is Epiphanius's own coinage, a pun on the group's rejection of the *Logos* (Word) of John's Prologue.

4. 4. Eusebius, *Ecclesiastical History* 3.24.1–2 and 3.25.1 (NPNF, 2nd ser., vol. 1). See note 53 below.

5. 5. Eusebius, *Ecclesiastical History* 6.14.5–7 (NPNF, 2nd ser., vol. 1, trans. McGiffert). Clement's fuller account holds that the Gospels with the genealogies (Matthew and Luke) were written first and that Mark recorded Peter's preaching. See newadvent.org/fathers/250106.htm.

6. 6. John 20:31 (NABRE). The evangelist's stated purpose stands at the end of what most scholars regard as the original conclusion of the Gospel (20:30–31); see note 36 below. A well-attested textual variant reads “continue to believe” in place of “come to believe.”

7. 7. John 1:1, 1:14 (NABRE). See bible.usccb.org/bible/john/1.

8. 8. The traditional enumeration of seven signs is Cana (2:1–11), the official's son (4:46–54), the paralytic at Bethesda (5:1–9), the feeding of the five thousand (6:1–15), the walking on the water (6:16–21), the man born blind (9:1–7), and the raising of Lazarus (11:1–44). The list is debated: some scholars exclude the walking on the water, which lacks the “sign” vocabulary and public witness, and treat the Resurrection as the climactic sign.

9. 9. The seven predicated “I am” sayings: the bread of life (6:35), the light of the world (8:12), the gate for the sheep (10:7, 9), the good shepherd (10:11), the resurrection and the life (11:25), the way and the truth and the life (14:6), and the true vine (15:1). The NABRE renders 10:7 “I am the gate for the sheep” (not “door”).

10. 10. John 8:58 (NABRE); cf. the other absolute “I am” sayings at 8:24, 8:28, 13:19, and 18:5–6, where the soldiers who come to arrest Jesus “turned away and fell to the ground” at his “I AM.”

11. 11. John 20:28 (NABRE). Thomas's confession forms the Christological climax of the Gospel, immediately before its original conclusion at 20:30–31.

12. 12. John 6:51 (NABRE); *Catechism of the Catholic Church* 1338: “The three synoptic Gospels and St. Paul have handed on to us the account of the institution of the Eucharist; St. John, for his part, reports the words of Jesus in the synagogue of Capernaum that prepare for the institution of the Eucharist: Christ calls himself the bread of life, come down from heaven.” See vatican.va.

13. 13. The cleansing of the Temple: John 2:13–22; contrast Mark 11:15–19 and parallels, where it falls in Jesus' final week. Whether John and the Synoptics record the same event placed differently for theological reasons, or two distinct events, is disputed.

14. 14. The three Passovers are named at John 2:13, 6:4, and 11:55 (with 12:1 and 13:1). The Synoptic outline mentions only the final Passover, which is why the “three-year ministry” derives from John.

15. 15. John 18:28 and 19:14 (NABRE): “It was preparation day for Passover, and it was about noon.” The NABRE note on 19:14 observes that noon was “the hour at which the priests began to slaughter the Passover lambs in the temple.” Cf. 19:31, 36. See bible.usccb.org/bible/john/19.

16. 16. On the crucifixion chronology and the proposed harmonizations — a deliberate Johannine theology of the Passover Lamb, competing calendars (including the solar-calendar hypothesis of Annie Jaubert), or John's greater accuracy — see Raymond E. Brown, *The Gospel According to John (XIII–XXI)*, Anchor Bible 29A (Doubleday, 1970), and *The Death of the Messiah* (Doubleday, 1994).

17. 17. John 21:24 (NABRE); cf. 19:35. The shift to the first-person plural — “we know that his testimony is true” — is the standard evidence that the Gospel reached its final form through a community or redactor vouching for the Beloved Disciple's witness. The Beloved Disciple appears at 13:23, 19:26–27, 20:2–8, and 21:7, 20.

18. 18. Theophilus of Antioch, *To Autolycus* 2.22 (ANF, vol. 2, trans. Marcus Dods): “the holy writings teach us, and all the spirit-bearing men, one of whom, John, says, ‘In the beginning was the Word, and the Word was with God.’” Theophilus wrote c. 180. See newadvent.org/fathers/02042.htm.

19. 19. Irenaeus, *Against Heresies* 3.1.1 (ANF, vol. 1, trans. Alexander Roberts and William Rambaut). See newadvent.org/fathers/0103301.htm. On Irenaeus's link to Polycarp, see his *Letter to Florinus*, quoted in Eusebius, *HE* 5.20.

20. 20. Irenaeus, *Against Heresies* 3.11.1 (ANF, vol. 1): John “seeks, by the proclamation of the Gospel, to remove that error which by Cerinthus had been disseminated among men, and a long time previously by those termed Nicolaitans.” See newadvent.org/fathers/0103311.htm.

21. 21. The Muratorian Fragment, lines on the Fourth Gospel (Roberts-Donaldson translation, ANF, vol. 5). The fragment is usually dated to the later second century, though a revisionist minority (A. C. Sundberg, G. M. Hahneman) argues for a fourth-century date, a proposal contested by Charles E. Hill and others. See earlychristianwritings.com/text/muratorian.html.

22. 22. Polycrates of Ephesus, quoted in Eusebius, *Ecclesiastical History* 5.24.2–3 (NPNF, 2nd ser., vol. 1, trans. McGiffert); cf. 3.31.3. Polycrates wrote c. 190 during the Quartodeciman controversy. The “sacerdotal plate” (the high-priestly *petalon*, Exodus 28:36) is a much-discussed detail. See newadvent.org/fathers/250105.htm.

23. 23. Papias of Hierapolis, quoted in Eusebius, *Ecclesiastical History* 3.39.4 (NPNF, 2nd ser., vol. 1). Papias asks after what “Andrew or… Peter… or John or Matthew” had said, and then, separately, what “Aristion and the presbyter John, the disciples of the Lord, say.” See newadvent.org/fathers/250103.htm.

24. 24. Eusebius, *Ecclesiastical History* 3.39.5–6 (NPNF, 2nd ser., vol. 1): “the name John is twice enumerated by him… there were two persons in Asia that bore the same name, and… there were two tombs in Ephesus, each of which, even to the present day, is called John's.” The distinction is Eusebius's inference from Papias's double naming, not a statement of Papias himself; Eusebius had a motive, since he wished to assign the Book of Revelation to the second John.

25. 25. Leon Morris, *The Gospel According to John*, NICNT, rev. ed. (Eerdmans, 1995); D. A. Carson, *The Gospel According to John*, Pillar New Testament Commentary (Eerdmans, 1991); Craig L. Blomberg, *The Historical Reliability of John's Gospel* (InterVarsity Press, 2001). All defend authorship by John the son of Zebedee, building on the cumulative internal argument of B. F. Westcott.

26. 26. Raymond E. Brown, *The Gospel According to John*, Anchor Bible 29 and 29A (Doubleday, 1966–1970); *The Community of the Beloved Disciple* (Paulist, 1979); and, for his revised view, *An Introduction to the Gospel of John*, ed. Francis J. Moloney (Doubleday, 2003), in which Brown records his inclination to regard the Beloved Disciple as an unknown minor disciple rather than John of Zebedee, with the Gospel written by a follower.

27. 27. Martin Hengel, *The Johannine Question* (SCM / Trinity Press International, 1989); Richard Bauckham, *The Testimony of the Beloved Disciple* (Baker Academic, 2007) and *Jesus and the Eyewitnesses* (Eerdmans, 2006; 2nd ed. 2017). Both identify the author with the “presbyter John” of Papias, an eyewitness disciple who was not one of the Twelve.

28. 28. Rudolf Bultmann, *The Gospel of John: A Commentary*, trans. G. R. Beasley-Murray et al. (Blackwell / Westminster, 1971; German original 1941). Bultmann posited a written “signs source,” a revelation-discourse source, and an ecclesiastical redactor, and read John against a Gnostic-Mandaean redeemer myth — a background now widely regarded as anachronistic.

29. 29. Second Vatican Council, *Dei Verbum* (1965), §§18–19. See note 61 below and vatican.va.

30. 30. New American Bible (Revised Edition), Introduction to the Gospel According to John: “It was probably written in the 90s of the first century,” with “the final editing of the gospel and arrangement in its present form” dating “probably… between A.D. 90 and 100.” See bible.usccb.org/bible/john/0.

31. 31. John A. T. Robinson, *Redating the New Testament* (SCM / Westminster, 1976), which argued for a pre-70 date across the New Testament; and, posthumously, *The Priority of John* (SCM, 1985).

32. 32. Ferdinand Christian Baur and the Tübingen school dated the Fourth Gospel to c. 160–170, reading it as a second-century synthesis rather than an apostolic composition. The position is now abandoned, in significant part because of the papyrus evidence discussed below.

33. 33. Rylands Library Papyrus P52 (P.Ryl. Gr. 457) preserves John 18:31–33 on the recto and 18:37–38 on the verso. It was published by C. H. Roberts, *An Unpublished Fragment of the Fourth Gospel in the John Rylands Library* (Manchester University Press, 1935), who judged “the first half of the second century” the most probable period of writing.

34. 34. Brent Nongbri, “The Use and Abuse of P52: Papyrological Pitfalls in the Dating of the Fourth Gospel,” *Harvard Theological Review* 98, no. 1 (2005): 23–48, argued that “the window of possible dates for P52 must include dates in the later second and early third centuries.” The bracket “125–175” is the proposal of Pasquale Orsini and Willy Clarysse, “Early New Testament Manuscripts and Their Dates,” *Ephemerides Theologicae Lovanienses* 88 (2012): 443–474, not Nongbri's or Roberts's.

35. 35. New American Bible (Revised Edition), Introduction to John: “Traditionally, Ephesus has been favored as the place of composition, though many support a location in Syria, perhaps the city of Antioch, while some have suggested other places, including Alexandria.”

36. 36. John 20:30–31 (NABRE). The NABRE note observes that “these verses are clearly a conclusion to the gospel and express its purpose,” and the introduction states that the author's purpose “is clearly expressed in what must have been the original ending of the gospel at the end of Jn 20.”

37. 37. On chapter 21 as an epilogue, the NABRE introduction notes that it “seems to have been added after the gospel was completed; it exhibits a Greek style somewhat different from that of the rest of the work.” The NABRE note on 21:1–23 adds that “even if a later addition, the chapter was added before publication of the gospel, for it appears in all manuscripts.”

38. 38. John 14:31 (“Get up, let us go”), followed by chapters 15–17 before the departure is narrated at 18:1 — the classic “double ending” of the farewell discourse. A comparable seam is the abrupt geographic jump between chapters 5 (Jerusalem) and 6 (“the other side of the Sea of Galilee”), which some scholars would smooth by reversing the order of the two chapters.

39. 39. New American Bible (Revised Edition), Introduction to John, on the internal “inconsistencies” and their probable origin “by subsequent editing in which homogeneous materials were added to a shorter original.”

40. 40. John 8:7 (NABRE). The pericope adulterae (7:53–8:11) is absent from P66, P75, Codex Sinaiticus, and Codex Vaticanus, among many other witnesses; the earliest Greek manuscript to contain it is the fifth-century Codex Bezae. It “floats” in the manuscript tradition, appearing after John 7:52, after 7:36, at the end of John, and after Luke 21:38.

41. 41. New American Bible (Revised Edition), note on John 7:53–8:11: “The story of the woman caught in adultery is a later insertion here, missing from all early Greek manuscripts. A Western text-type insertion, attested mainly in Old Latin translations… The Catholic Church accepts this passage as canonical scripture.” See bible.usccb.org/bible/john/8.

42. 42. Council of Trent, Fourth Session (8 April 1546), *Decree Concerning the Canonical Scriptures*, which receives the sacred books “with all their parts, as they have been used to be read in the Catholic Church, and as they are contained in the old Latin vulgate edition.”

43. 43. On Heracleon (fl. c. 170s), the Valentinian whose commentary on John survives only in the roughly forty-eight fragments quoted by Origen in his *Commentary on the Gospel of John*, see A. E. Brooke, *The Fragments of Heracleon* (Cambridge University Press, 1891); Elaine Pagels, *The Johannine Gospel in Gnostic Exegesis* (Abingdon, 1973); and Carl Johan Berglund, *Origen's References to Heracleon* (Mohr Siebeck, 2020). It is best described as the earliest known commentary on any book of the New Testament.

44. 44. Ptolemy's reading of the Prologue is preserved and refuted in Irenaeus, *Against Heresies* 1.8.5 (ANF, vol. 1): the Valentinians held that John “indicated the first Ogdoad” in distinguishing God, the Beginning, and the Word. See newadvent.org/fathers/0103108.htm. The Nag Hammadi *Gospel of Truth* (Codex I,3), associated with the Valentinian school, echoes Johannine language without being a formal commentary.

45. 45. The attribution of both the Gospel and Revelation to Cerinthus is reported by Epiphanius, *Panarion* 51.3 (see note 46). On Cerinthus as the target of John's Gospel in the tradition, see Irenaeus, *Against Heresies* 3.11.1 (note 20).

46. 46. Epiphanius of Salamis, *Panarion* 51 (trans. Frank Williams, Nag Hammadi and Manichaean Studies 35–36; Brill, 1987–1994), writing c. 375, coins the mocking name “Alogi” for the group that rejected John's Gospel and the Apocalypse, punning on their refusal of the *Logos*. The placement of the group in later-second-century Asia Minor is the reconstruction of modern scholars, not a date given by Epiphanius.

47. 47. Irenaeus, *Against Heresies* 3.11.9 (ANF, vol. 1): those who “do not admit that aspect [of the evangelical dispensation] presented by John's Gospel, in which the Lord promised that He would send the Paraclete; but set aside at once both the Gospel and the prophetic Spirit.” The Ante-Nicene Fathers editors gloss the group as Montanists, but the identification is an editorial insertion, not Irenaeus's word, and is likely mistaken, since these John-rejecters appear to have been opponents of the Montanists.

48. 48. Eusebius, *Ecclesiastical History* 3.28.1–2, preserves Gaius attacking the “revelations” ascribed to Cerinthus, which most read as bearing on the Book of Revelation rather than the Gospel. The further claim that Gaius rejected the Gospel of John rests on the twelfth-century Syriac writer Dionysius bar Salibi, reporting a lost work of Hippolytus (*Heads Against Gaius*), and is disputed.

49. 49. Irenaeus, *Against Heresies* 3.11.8 (ANF, vol. 1). See newadvent.org/fathers/0103311.htm.

50. 50. Irenaeus, *Against Heresies* 3.11.8 (ANF, vol. 1). In Irenaeus's scheme the lion (royal power) belongs to John, the calf or ox (sacrifice) to Luke, the man to Matthew, and the eagle (“the winged aspect of the Gospel,” the prophetic Spirit) to Mark — the reverse of the later Western pairing of John with the eagle and Mark with the lion.

51. 51. Jerome, Preface to his *Commentary on Matthew* (c. 398), gives the scheme that became standard in the West: the man to Matthew, the lion to Mark, the ox to Luke, and the eagle to John. Augustine, *De consensu evangelistarum* 1.6.9, offers yet another arrangement (the lion to Matthew, the man to Mark, the ox to Luke, the eagle to John).

52. 52. Augustine, *Tractates on the Gospel of John* 36.1 (NPNF, 1st ser., vol. 7, trans. John Gibb): John “not undeservedly in respect of his spiritual understanding compared to the eagle, has elevated his preaching higher and far more sublimely than the other three.” See newadvent.org/fathers/1701036.htm.

53. 53. Eusebius, *Ecclesiastical History* 3.24.1–2 (“his Gospel… is known to all the churches under heaven, must be acknowledged as genuine”), 3.24.17 (“of the writings of John, not only his Gospel, but also the former of his epistles, has been accepted without dispute”), and 3.25.1 (“First then must be put the holy quaternion of the Gospels”). NPNF, 2nd ser., vol. 1. See newadvent.org/fathers/250103.htm.

54. 54. On the sustained Eastern doubt over the Book of Revelation, which shared John's name but not his easy passage into the canon, see the companion post on [the Book of Revelation](/book-of-revelation/). John's Gospel appears without dispute in Athanasius, *Festal Letter* 39 (367), and in the canons of the councils of Hippo (393) and Carthage (397).

55. 55. Charles E. Hill, *The Johannine Corpus in the Early Church* (Oxford University Press, 2004), which names and challenges the “orthodox Johannophobia” paradigm associated with J. N. Sanders, *The Fourth Gospel in the Early Church* (Cambridge University Press, 1943), and T. W. Manson. Hill argues that orthodox use of John was in fact early and widespread.

56. 56. On the background of the Johannine *Logos*, see the NABRE note on John 1:1–18, which relates the Word to the creative word of Genesis 1, to personified Wisdom (Proverbs 8; Wisdom; Sirach), and to the Hellenistic *logos*. The Wisdom tradition is generally regarded as primary, with the philosophical resonance secondary; on Philo's Logos as a parallel rather than a source, see C. H. Dodd, *The Interpretation of the Fourth Gospel* (Cambridge University Press, 1953).

57. 57. *Catechism of the Catholic Church* 291 (creation through the Word, quoting John 1:1–3; see vatican.va) and 461 (“Taking up St. John's expression, ‘The Word became flesh,’ the Church calls ‘Incarnation’ the fact that the Son of God assumed a human nature”; see vatican.va).

58. 58. The “Book of Signs” (chapters 1–12) and “Book of Glory” (chapters 13–20, with chapter 21 as epilogue) is the framework standardized by Raymond E. Brown in his Anchor Bible commentary; C. H. Dodd had earlier used “Book of Signs” for a similar block.

59. 59. C. H. Dodd, *The Interpretation of the Fourth Gospel* (Cambridge University Press, 1953), and *Historical Tradition in the Fourth Gospel* (Cambridge University Press, 1963), on “realized eschatology” (e.g., John 5:24). John also retains future-eschatological language (“I will raise him on the last day,” 6:39–40, 54; 5:28–29), so scholars often speak of an “inaugurated” rather than purely realized eschatology.

60. 60. The Paraclete sayings: John 14:16–17, 14:26, 15:26, 16:7–15; the “high-priestly prayer” of John 17. On the influential but contested reading of the synagogue-expulsion passages (9:22; 12:42; 16:2) as reflecting a later community conflict, see J. Louis Martyn, *History and Theology in the Fourth Gospel* (Harper & Row, 1968; rev. ed. Westminster John Knox, 2003).

61. 61. Second Vatican Council, *Dogmatic Constitution on Divine Revelation (Dei Verbum)* (18 November 1965), §§18–19. Section 18 affirms “that the four Gospels are of apostolic origin… the fourfold Gospel, according to Matthew, Mark, Luke and John”; section 19 states that the Church “unhesitatingly asserts” their historical character while noting that the evangelists wrote “selecting some things… reducing some of them to a synthesis, explaining some things in view of the situation of their churches.” See vatican.va. On the freedom of Catholic critical scholarship, see also the shift in the Pontifical Biblical Commission's posture after 1955.

62. 62. The three great baptismal Gospels of the Lenten scrutinies (Third, Fourth, and Fifth Sundays of Lent) are the Samaritan woman (John 4), the man born blind (John 9), and the raising of Lazarus (John 11). The Roman Missal appoints these Johannine readings for use with the scrutinies of the elect, and they may be read in any year when the scrutinies are celebrated.

63. 63. The Passion according to John (18:1–19:42) is proclaimed at the Good Friday liturgy of the Lord's Passion every year in the Roman Rite; the Prologue of John (1:1–18) is the Gospel of the Mass during the Day on the Nativity of the Lord, and historically served as the “Last Gospel” read at the end of every Tridentine Mass.
