The Gospel of Thomas and the Platonists on Oneness

The following four chapters focus on the Thomasine notion of perfection. I begin with the notion of “oneness.” Many Thomasine sayings invite the readers to “become one.” This motif was discussed in a seminal article by A.F.J. Klijn, who argued that it comes from the Jewish speculations about Adam being “one.”1 In this chapter, I am going to revisit Klijn’s hypothesis and show that, even though the Thomasine motif of becoming one might have been influenced by certain Jewish traditions, it was to a great extent shaped by Platonist thought. I am also going to discuss whether the Platonist origins of the motif might shed some light on the sayings of the Gospel of Thomas that employ the term μοναχός.
