In Seek to See Him April DeConick argues that the Gospel of Thomas, contrary to the way Thomas is normally understood, does not originate from gnostic traditions. Instead, she proposes that Thomas is best explained by Hermetic and Second Temple Jewish mystical traditions.

DeConick substantiates her proposal by first examining the developmental stages of the Gospel of Thomas, questioning the classification of Thomas as gnostic on the basis of Thomas' dualism and his speculation about original sin. DeConick carefully delineates the difference between Thomas' and gnostic views of the world and of salvation before going on to demonstrate the crucial role of purification, heavenly ascent, and visio dei - final transformation through an experience of seeing God - in this Gospel. In the end, DeConick shows that Thomas is best explained as arising from the fusion of Jewish Mysticism and Hermetic praxis and not as being shaped by gnostic traditions.
