Furthermore, it is commonplace in the scholarly community to ascribe GosPhil to the Valentinian School, but I wish to propose the following: given the number of allusions to ApJohn included therein, I would go as far as to claim this very work for the Sethians/Johannine secessionists. Some of the treatise does stray from the Word stochastically, perhaps due to geographic penmanship, perhaps due to some Valentinian influence given the date of composition (sometime around the 3rd century.) However, the Sethian/Johannine secessionist Verses justify including this treatise in My Personal Canon. Furthermore, a member of the Immovable Race will be able to determine those that are salient.
Support for this position comes from Dr. Larry Hurtado in Lord Jesus Christ, p. 534: “In the fluid and varied world of early Christianity, it is quite likely that Christians of various orientations experimented with appropriating this or that feature of belief and practice without buying into the whole version of Christianity from which the belief of practice derived. Thus vocabulary and themes that may have originated from Valentinian discourse could easily have been appropriated by Christians who did not imagine themselves to be Valentinians. We have to allow for the strong possibility of considerable eclecticism in the religious vocabulary and conceptual categories of Christians in the early period. Some early Christians were concerned for tradition and conventionalization of beliefs and practices (e.g. Clement of Rome,) but others seem to have been more eclectic (e.g. Clement of Alexandria,) more ready to appropriate religious terminology and ideas that they perceived as interesting and useful, and less apprehensive as to its derivation.”
