And know, it really isn't an answer. I listed the scripture passages, old and new testament, and nowhere does it explain the Trinity as we teach it today.
The answer to the origin of the Son and the Holy Spirit is in the Church's teaching that in God there are two internal divine processions. The word procession is used here to mean the origin of one from another . . . one proceeding from another. He can try and twist it otherwise, but the fact is that it simply isn't explained that way in scripture. Which brings me back to the point that sola scriptura is unbiblical and unreliable as a source to use when debating theology, and gives little to no weight for his arguments on saints.
