Would you mind explicitly stating (perhaps again) what you believe and where it has been officially condemned? That may be a beneficial starting point, for me anyways.
Sure. What I believe is that there is no
real distinction between God the Father, God the Son and The Holy Spirit. The same way that God’s omnipresence, omnipotence, omniscience, etc. are not
really distinct in God. They are only
logically distinct.
Real distinctions are distinctions that exist outside of the mind, or outside of ways of thinking. Logical distinctions are only distinctions in ways to think about the same thing. For example, the distinction between an unmarried man and a bachelor is not a
real distinction, because all unmarried men are bachelors and vice versa. There is, however, a *logical distinction, in that the term “unmarried man” emphasizes certain things that couldn’t otherwise be emphasized by the term “bachelor.”
This is how God’s attributes are viewed. When we speak of God’s omnipresence as opposed to his Existence, we are emphasizing certain things about him, or analyzing him through a specific lense, even though in reality there is no distinction between God’s omnipresence and his Existence.
My reasoning is that if the Father, the Son, and the Holy Spirit are
really distinct, it would mean that there is a distinction in God that doesn’t only exist in the mind. It would be some kind of metaphysical/ontological distinction that exists in God. This can only be possible if God is a composite of act/potency (since distinctions are due to differences in potency). But this obviously can’t be since God is Pure Act and thus has no potency whatsoever.
This view (the view that I’m arguing for) is condemned by the Church. The Catechism says
The divine persons are really distinct from one another . "God is one but not solitary."86 “Father”, “Son”, “Holy Spirit” are not simply names designating modalities of the divine being, for they are really distinct from one another: "He is not the Father who is the Son, nor is the Son he who is the Father, nor is the Holy Spirit he who is the Father or the Son."87 They are distinct from one another in their relations of origin: "It is the Father who generates, the Son who is begotten, and the Holy Spirit who proceeds."88 The divine Unity is Triune.
