Why not dismiss the trinitarian belief outright

[Vicki Q]

Yeah, right Trinity is so original and the resemblance to trinities in other religions is just... what exactly? A coincidence? Just like turning Jesus' mother into Magna Mater is a coincidence, Jesus's passion being like the passion of Tammuz and the passions of other Gods. Jesus' resurrection is just like resurrections of other gods, and so on.

Especially since Trinity doesn't make sense in Christianity so it's obviously forced since Jesus is his own father, and Mary is his daughter, sister, mother, and whatnot.

Firstly, as has already been noted by others, groups of divinities can be found in pretty much any integer value, repeatedly for some integers. That some of them are in threes is pretty much a coincidence, yes.

Secondly, the NT is clear and non-negotiable on the Oneness of God. In what sense are the groups of three you name one single entity in the same sense?

Finally, you have still not produced any actual evidence that Early Christianity got a Trinity from anywhere.

There was no singular community portrayed by the nt, either.  In fact, the thrust of whomever wrote Paul was precisely this.  That Christianity had become fractured and unchristian, Christians themselves a minority in the community of Christian faith.  Beset on all sides by heresy and division.

You’d have to excise history -and- the actual contents of the nt to think otherwise.

Paul didn’t disagree with himself, and that’s about it, if that’s what you mean………

I absolutely disagree, but don't need to argue the point, because even if it were correct that's still no evidence of a belief in multiple Gods.
