My own research on the peer reviewed research on the mythology of a historical Jesus, in addition to the questions of the accuracy of translations, I'm not even clear whether Thomas existed as a historical person.
Indeed, the line of thought that the Jesus narrative of the early Christian narrative copies so many concepts of various regional religions, I would not be surprised that the early Greek and Roman Christians took Epicurus into account before they settled on an agreeable account narrative of Jesus up to and at the Council of Nicea and continuing for the millennia that followed.
