Whether God is one?

Objections

Objection 1 : It seems that God is not one. For it is written "For there be many gods and many lords" (1 Cor. 8:5).
Objection 2 : Further, "One," as the principle of number, cannot be predicated of God, since quantity is not predicated of God; likewise, neither can "one" which is convertible with "being" be predicated of God, because it imports privation, and every privation is an imperfection, which cannot apply to God. Therefore God is not one.
