This commentary on the Gospel of Thomas discovered in Nag Hammadi in 1945 consists of an introduction, criteria for the study of historical Jesus and a detailed commentary on all 114 logies of the Gospel of Thomas. He contradicts the claim of a Gnostic origin of the logies and also contradicts the dependence of the Gospel of Thomas on the Synoptic or the Gospel of John. Rather, the Gospel of Thomas contains traditions that are independent of the Synoptics and the Gospel of John and belongs to the area of early Jewish Christianity.
