If the Bible taught only these two facts, there would be no logical problem at all in fitting them together, for the obvious solution would be that there are three Gods. The Father is fully God, the Son is fully God, and the Holy Spirit is fully God. We would have a system where there are three equally divine beings. Such a system of belief would be called “polytheism”—or more specifically “tritheism,” belief in three Gods. But that is far from what the Bible teaches.
