the proper name for it is ontology

relates to set theory as well, you could use set concepts to explain it

God is the infinite set

all things are members of the God set

equality in set theory means the identical set, obviously this means no subset of the God set can be God

The trinity itself is a subset of the God set, the Father, the Son and the Holy Ghost are subsets of God

ah yes and the last one that makes it all the best fun

Any infinite set can contain another infinite set

i was reading about this a few weeks ago, how there is many kinds of infinity... i suppose there must be infinite kinds of infinity, ultimately

in my opinion, to know mathematics, arithmetic, set theory, algebra, physics, and to not have an inkling of the God set is wanton blindness
