The Trinity is the logical consequence of divine revelation in the Bible.

God reveals himself in three personalities. He is Father because a Son was born.

The Son carries the DNA of the Father and is not an inferior being because of his sonship, but voluntarily subordinates himself to the Father because of his sonship.

God is present because he is spirit and can be and act everywhere at the same time. God is not human and is therefore beyond our imagination.

No one does anything that the other would not do.

We cannot grasp this unity with our minds. When the Holy Spirit comes, Jesus promises: “In that day you will know that I am in my Father, and you in me, and I in you” (John 14:20). “And we will come to him and make our home with him” (Johnn 14:23). This unity is ultimately a divine mystery. For God cannot be grasped by our thinking. Otherwise we would be divine. Because we cannot grasp it does not mean that it is not so.

Anyone who wants to explain God with human logic cannot believe that God is one and not one (achad and not jachid). Jesus already had the problem that people did not understand. He encourages them to believe (John 14:11).
