John

The Gospel of John stands apart from the other three Gospels (the "Synoptics") in structure, style, and theology. It opens not with a birth narrative or baptism but with a cosmic prologue identifying Jesus as the Logos — the Word that was with God and was God from the beginning. Its Jesus speaks in extended theological discourses rather than pithy parables, performs "signs" rather than miracles, and is conscious of his divine identity from the outset.

Traditional attribution identifies the author as John the son of Zebedee, one of the twelve apostles, writing in Ephesus in extreme old age. The Gospel itself refers to an unnamed "Beloved Disciple" as its source (21:24). Whether this figure is John the apostle, another John (the "Elder" mentioned by Papias), or a literary construct remains one of the great unsolved questions of New Testament scholarship.

The three Johannine epistles (1, 2, and 3 John) are closely related in style and theology to the Gospel but may be by a different author within the same community. They address internal conflicts about Christology and ethics that suggest a community under pressure.

The Revelation of John (the Apocalypse) is attributed to a "John" who was on the island of Patmos, but its Greek style is so different from the Gospel that most scholars consider it a separate author — traditionally distinguished as "John of Patmos."

The Gospel is generally dated to the 90s CE, making it the last of the four canonical Gospels. Its influence on Christian theology has been immense — it gave Christianity the language of incarnation, light, truth, and eternal life that shaped centuries of doctrine and devotion.
