Paul quoting from Isaiah two non Trinitarian verses prove the Nicene Trinitarian formula?

No. I can quote Isaiah myself, but that does not make my pronouncements any more true than they are unto themselves.

Paul quoting from Isaiah two non Trinitarian verses prove the Nicene Trinitarian formula?

I wasn't attempting to prove the Nicene Trinitarian formula, I was merely refuting your false assertion Paul does not quote God except for the three introductory verses in Acts 9.

Here's another example among many of Paul quoting God:

Three times I pleaded with the Lord to take it away from me. But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness."
2 Corinthians 12:8-9

To whom was Paul praying, and who was talking back to him?

No. I can quote Isaiah myself, but that does not make my pronouncements any more true than they are unto themselves.

Now, you do not have to answer my questions, but you did not answer my fill-in-the-blank question as to who is speaking in Isaiah 28:17.

Cordially,
