The demarcation between monotheism and polytheism is not as clear as most of us imagine. Polytheists maintain that each and every god is a manifestation of a unity, and monotheists discern distinct loci of behaviour within their one God. In the Christian tradition, the Bible is understood to present God as manifesting Himself in three persons: the Father, the Son and the Holy Spirit, and at the same time affirming that God is One.
Mainstream Christianity has alway wrestled with these two views on God. How can God be One and yet Three? The best it has been able to come up with is the hope that there is an explanation, known and knowable only to God. This gap must involve at least one explanatory element. That gives an Occam score of 0100, relative to QO.
QO has a natural explanation for the Trinity, with an Occam score of 0000, relative to QO.
