Note 5 — Chapter VII · POST-CHRISTIAN GNOSTICS
Reading edition
The Canonical Apocalypse was probably written after the siege of Jerusalem by Titus in 70 A.D., while the first unmistakable mention we have of St John’s Gospel is by Theophilus of Antioch a hundred years later. Earlier quotations from it are anonymous, i.e. they give the words of the Gospel as in the A.V. but without referring them to any specified author. See Duchesne, Early Christian Church, Eng. ed. pp. 102, 192.
