I think you misinterpreted the article.
The article is an explanation of one of St. Thomas Aquinas’ proofs. It is not that God is impersonal, or some being that is disconnected. The article and proof just explain what God is in basic common and logical terms…that is, not yet arriving at the complexity of the Truth, which logically formulates that Christ is God.
God says I AM. God is eternal being. He has no beginning nor end, for He is eternal.
Now, Christians can use this if they could just get someone to sit through the whole proof. The problem is that atheists typically don’t define God. First, they try and define a Christian God which, to them, must be a myth. I know this is a problem, but they don’t see it.
See, back when we were but Jesus’ plan (medieval times) “proofs” were logical proofs. Now “proofs” are physical proofs. Whereas before reason prevailed, now sense prevailed when it comes to the science of God. The problem is that Jesus’ kingdom is not of this world, and atheists apply the physics of this world to Jesus’ extra-terrestial (not of this world) kingdom, and to Jesus Himself.
So the proof is correct logically, and rationally; even if one is not Christian one can see that. Unfortunately atheists want to see or taste or touch or smell God, and this is only possible if they accept He exists, because then they can go through some catechism and receive the Body of Our Lord.
I don’t know if this all makes sense. God bless,
