I'll leave the Mohammed stuff aside for now. I'm not convinced, especially when you're still using their talking points about the trinity being polytheism. Nobody, I mean nobody, attacks Christianity from a unitarian perspective, not even the most militant atheists.

You didn't answer why, of all people on this conspiracy theory board, you're asking deep theological questions of me, and moreover not taking the answers very seriously.

Honestly, though, if you expect a systematic theology from the bible like geometry or Newtonian physics, you won't get it. There is a limit to human reason, which is why certain things are revealed by divine revelation.

To your comment: Jesus as the 2nd person of the Trinity had two natures, a human nature and his nature as God. That's what consubstantial mean, of two essences but the same identity. Outside of time, God always existed, but inside of time he became incarnate of the virgin Mary and became man while still God. This, of course, is the divine revelation I'm referring too.
