If you're looking for a scholarly book on the NT I can recommend Bart Ehrman. As for Constantine, you put a lot on his shoulders. He supported the Roman Church against the others for purely political reasons, he wanted them close to be able to control them.IMHO----the BIGGEST fluke of history was Constantine. I am not sure all that much is actually KNOWN about James or if
there really was a James. " Q " is only a conjecture. I have no doubt that SOME of the story that appears in the NT is true-----bits and pieces only. Constantine created a perversion that inspired islam and shariah, the Inquisition
and adolf. Hussein bin ali and his idiot wife Fartimah
(something like lady Macbeth) run a close second. Iran
is Fartimah's fault
Constantine's "support" was far more than mere support.
HE CREATED THE 'holy' roman empire----aka REICH.
centered in rome. He did not merely ALLOW the religion
to flourish------he outlawed all others and established its
IMPERIALIST agenda. I have seen Ehrman--long ago.
Constantine legalized Christianity. It was Theodosius who made it the only legal religion and who imposed severe penalties on Jews
yes---all part of the same CORPORATION-----constantine INC with dozens of subsidiaries with varying business
connections ----kinda like the "FAMILIES" of the New York
Mafia
