In other words, you cannot prove it. Your flailing is only increasing evidence that when it comes down to it, the OPC is a man made construction; a splinter of a splinter of a splinter of a splinter of a group that rejected Christianity.
The OPC is not Christian; it does not hold Christian beliefs except by accident; it cannot abide Christianity and it posts all bizarre manner of beliefs on its official web pages which include an encouragement to believe that your pets will join you in Calvinist heaven.
You also imply Paul could err in the Scriptures which is a bizarre statement for a "Christian" to make. The Scriptures were written by inspiration of the Holy Spirit, and as such, they are infallible in matters of faith and practice.
I never said 'err'. If Paul was human, he could have left out the Trinitarian doctrine, which he did. You have been challenged to prove otherwise, since I showed his non Trinitarian formula.
Since the historic, orthodox Christian church considers Paul a Trinitarian, it is up to apostates like you to support your opinion that Paul is not Trinitarian.
We do not worship Paul. We consider Paul one of the greatest apostles. You say that Paul is Trinitarian. You prove it. Go ahead. Feel free to put your proofs where your mouth is.
You, OTOH, had only your goofy opinion that Paul was not Trinitarian.
So this time you jump through the hoops, Mark. You disprove 2,000 years of Christianity. You labeled Paul anti-Trinitarian, a slander denied by the Christian world, so you prove your opinion which swims and sinks against the current.
