Mark Goodacre makes the case that the author of The Gospel of Thomas is, after all, familiar with the Synoptic Gospels. He shows that the arguments for independence are inadequate and that the degree of agreement between Thomas and the Synoptics is far too great to be mediated by oral tradition.

The Gospel of Thomas is the most controversial of the non-canonical gospels and the most important source outside the Gospels for our understanding of the historical Jesus and Christianity's origins. Mark Goodacre makes a detailed and compelling case that the author of The Gospel of Thomas is, after all, familiar with the Synoptic Gospels. He shows that the arguments for independence are inadequate and that the degree of agreement between Thomas and the Synoptics is far too great to be mediated by oral tradition. He suggests that Thomas features tell-tale signs of Matthew's and Luke's redactions and that the Gospel should be dated to the early to middle second century, when its author was looking for a means of lending the voice of his enigmatic Jesus an authoritative, Synopic-sounding legitimacy.
