I know this is not orthodox, and might be heretical, but it is just a question. Is it theologically plausible, acceptable to call God the Father, the Father of God. I do not do this in prayer, but am just curious.
It’s theologically plausible, but it’s not conventional.
We call Mary the “Mother of God,” (Theotokos) when we strictly mean that she is the mother of the Second Person of the Trinity who shares in the divine Godhead. We do not mean, by that title, that Mary is the mother of the fullness of the Trinity (the fullness of the Trinity is also properly called “God”).
When we say that “Jesus is God” we do not mean that “Jesus is the Trinity,” although it is a challenge to clearly differentiate these expressions in our limited human language or thought.
The Church defended the title “Theotokos” against those (Arians) who would argue, “Mary is the mother of Jesus, but not the mother of God.” This was an attempt to deny the divinity of Jesus.
So, I suppose, if we can call Mary the “Mother of God” (with a certain understanding) then we can call God the Father the “Father of God” (with the same understanding). But it would be a highly unconventional extension of this reasoning. After all, nobody (not even the Arians) questions the divinity of the Father.
George Bush senior, the father of George W. Bush, is still a Bush. Now, does it make sense to call George Bush senior “The father of Bush” when he himself is a Bush? However you feel about that answer, is the same regarding calling God the Father, “The Father of God”. If it makes sense to you in one instance, than it is equally correct in the other and vice versa.
