I remember we had this discussion on the PB a little while ago only the roles were reversed and Mr Manata was defending TAG against Binity / Quadinity.
I can't pretend to understand half the issues going on in this debate and I tend to lean towards the anti-TAG side on this but I think a word can be said for TAG in the area of the doctrine of the necessity of the Trinity according to the scriptures. The number of persons constituting the Godhead is something hidden from the light of nature. Believing God is three in one is entirely a matter of faith known only by special revelation. In the Bible God reveals himself as Father, Son and Spirit. To believe this and more is to add to God's revelation and commit idolatry (Deut 4:2; 12:32; Rev 22:18). I think Sola Scriptura and the RPW makes a quadinity impossible.
