I understand that the opening post may appear complicated to those who have not become familiar with the terminology related to the conflict between two series of Christian books - 1) the NTC = NT canonical books, and 2 - the NTA = NT apocryphal books. This conflict involves the study or heretics and heretical writings, is generally called heresiology and is championed by the writings of the orthodoxy AGAINST the writings of the heretics.
Having said this, tangentiation has lead to a discussion of the so-called "Christian house-church" at Dura Europos. Whether Yale Divinity college has arrived at their interpretation of one room in a house at Dura Europos being "Christian" in a legitimate fashion, or whether the identification of its being "Christian" is simply a product of 1930's confirmation bias by the Yale Divinity team and its sponsors.
A further discussion related to the difference between "Christian" and "Chrestian" in the earliest sources is an added element that appears all through the evidence from antiquity and has not been satisfactorily resolved. Recently it was demonstrated that - contrary to all the modern translations - Chrestos and Chrestians appear throughout the Nag Hammadi library for example. What does this mean? Nobody knows at the moment.
Finally people will notice that Huller wants to keep discussing the mountainman theory that Constantine commissioned the invention of the NT canonical literature and the church history of Eusebius in the epoch 312-324 CE. Whereas the OP makes it crystal clear that everyone can retain their pet theories for the NT canonical (NTC) literature as either historical sources from the 1st / 2nd centuries (where Jesus is historical) OR whether the NT canonical material is a fabrication of the 1st / 2nd century (where Jesus is either mythical or fictional).
What the OP outlines is an alternative theory for the NT Apocryphal literature which is independent of the NT canonical literature no matter in which century the NT canonical literature first appeared on planet Earth. I hope this clarification helps.
