A.S.K. your way to proof.

In short the gospel is bunk because the oldest copy was written after the rest of the bible was written and compiled into a singular book. then sometime later (100 year or so) the gospel of thomas supposedly hits the scene but is never used or spoken of till 1945?!?!

is you stuped?

Drich,

This is why I have difficulty continuing to "dialogue" with you (emphasis mine):

The earliest surviving written references to the Gospel of Thomas are found in the writings of Hippolytus of Rome (c. 222–235) and Origen of Alexandria (c. 233).[22] Hippolytus wrote in his Refutation of All Heresies 5.7.20:

[The Naassenes] speak...of a nature which is both hidden and revealed at the same time and which they call the thought-for kingdom of heaven which is in a human being. They transmit a tradition concerning this in the Gospel entitled "According to Thomas," which states expressly, "The one who seeks me will find me in children of seven years and older, for there, hidden in the fourteenth aeon, I am revealed."

This appears to be a reference to saying 4 of Thomas, although the wording differs significantly.
Origen listed the "Gospel according to Thomas" as being among the heterodox apocryphal gospels known to him (Hom. in Luc. 1).
In the 4th and 5th centuries, various Church Fathers wrote that the Gospel of Thomas was highly valued by Mani. In the 4th century, Cyril of Jerusalem mentioned a "Gospel of Thomas" twice in his Catechesis: "The Manichæans also wrote a Gospel according to Thomas, which being tinctured with the fragrance of the evangelic title corrupts the souls of the simple sort."[23] and "Let none read the Gospel according to Thomas: for it is the work not of one of the twelve Apostles, but of one of the three wicked disciples of Manes."[24] The 5th-century Decretum Gelasianum includes "A Gospel attributed to Thomas which the Manichaean use" in its list of heretical books.[25]
