Why Yahweh? (Or Allah, or Zeus, etc.)

[FallentoReason]

But they are considered canonical, hence why the epistles I mentioned are in the Bible. Maybe you meant to say the Gnostic documents? I've read that they weren't accepted because they didn't focus on Jesus' "humanity" enough.

So, as usual, christians cherry pick the good bits from the bible and pretend the rest doesn't exist. Only in this case they literally denied that it was part of the bible, though I doubt it had much to do with whether the documents were accurate or not; in fact they may have been more accurate.

Well, at the time of all these documents being penned there was no "Bible" as such because the documents weren't canonized yet and therefore there was no "NT" yet. It's simply another case of humans using their own judgement to portray this wishful thinking that we are infact special and that some Jew really died for us. It's no different to Christians today using their own moral compass whenever they realise the OT is barbaric and they therefore need to tone it down through mental backflips. In a nutshell, the moral of the story is that there is no "Holy Spirit" guiding any of them.
