Citations from the Gospel of Philip

But if, (it says) it (sc. the soul) is found to have begotten a son, it is kept down below, until it is able to bring up its own children and draw them up to itself."
(Translation from Greek by S.J Gathercole)

The Four Gospels and the One Gospel of Jesus Christ
by Martin Hengel
How could the word, 'gospel', be used both by Paul for a proclamation which seems to include no narrative about the earthly Jesus, and by the author of the Gospel according to Mark and his successors, as a title works, which adopt an essentially narrative form? Why did the church, in forming its canon of scripture, choose to include four different and sometimes contradictory accounts of the life of Jesus, when others, like Tatian and Marcion, opted for a harmony, for one account? more
