Christians

[DeistPaladin]

You begin by getting trinitarianism right, but then end by getting it wrong. That is rather curious.

How do you know I got it wrong? Nobody really understands it.

bold emphasis of your post mine:

If God is in three separate persons, as trinitarianism teaches, then Jesus cannot be a separate being from Yahweh;

So three separate persons can't be separate from each other? Jesus is a separate person from Yahweh but can't be separate? I'm so glad you cleared that up.

He was praying to the Father who is God no more or less than Jesus himself is; that is, he was praying to a distinct person, not a distinct god.

So he's a distinct being with a different will but part of the same god and therefore the same being but they're separate and distinct but not?

All of Paul's letters predate both the synoptics and John's gospel, as do other letters in the New Testament, all of which correspond to the rich Christology and soteriology found in John's gospel (e.g., Titus 2:13).

Roughly half the epistles of Paul are of dubious authenticity. Titus is one of the dubious epistles.

That the scriptures, ancient creeds, liturgies, systematics and so forth all confirm that orthodox Christianity has never taught three separate gods.

There was no orthodox Christianity prior to Nicaea. The Marcionites taught there were two separate gods. The Ebionites taught that Jesus was a mortal adopted by God as a son. The Arians taught that Jesus was an angel. Any of these options were at least consistent and clear about what Jesus was.
