The Gospel of Truth.

        For the present one can discuss only these published documents. First came the Gospel of Truth, which may be the Valentinian “gospel” of which Irenaeus spoke. It is certainly not a “gospel” in any conventional sense (indeed, the title may have been invented because of its opening line); instead, it is a mystical meditation or series of meditations on the meaning of salvation as given through Jesus. Its theological outlook is close to heterodox Judaism and heterodox Christianity; perhaps it was actually written by Valentinus toward the middle of the second century, but this hypothesis is most uncertain. W. C. van Unnik has shown that in it there are reflections of most of the New Testament books, including Hebrews and Revelation. If it comes from about 150 or even earlier such usage confirms the existence of a New Testament collection at an early date.
