We will consider one more objection from Taymiyyah. It is that if the Son is begotten, then he must “separate” off from the Father. For everything that is begotten separates off from its source. If it were to remain within the source, it could not be begotten. That is the objection.
The objection works for things material. For everything material involves place, and with regard to things material, distinction of thing entails distinction of place. The child leaves its mother. This is very simple.
However, the question at hand regards God. We should pose a question: If there were begetting in God, would it be material? The answer is obviously “no”. No argument can prove that there is begetting in God. That is, no theological argument on the topic. We could, however, make the case for Christianity as a whole. And if it as a whole bears the indicators of divinity that no other religion bears, then we reasonably give credence to it as a divine religion. And that is a remote argument for the Trinity, since Trinitarian doctrine is part of Christianity.
But we grant that no theological argument can prove that God begets. However, can we observe an order of “emanation” that becomes increasingly more refined, more intimate and interior, the higher we go in nature? Yes, we can. Stay tuned.
