Johannine literature
Johannine literature is a modern collective term for five New Testament writings that early Christian tradition linked in various ways with John the Apostle or a related circle of teachers: the Gospel of John, the three Johannine epistles (1 John, 2 John, and 3 John), and the Book of Revelation. The designation identifies a literary family with shared vocabulary and theology without implying single authorship, and it reflects how ancient readers grouped the texts while acknowledging distinct voices within them.
