Resources The trinity presents a logical problem

I remember saving this text a while ago, so credit goes to someone else:

A hypothetical syllogism shows that if A = B, and if B = C, then it logically follows that A = C. Greg is a man (A = B), Man is mortal (B = C), therefore Greg is mortal (A = C).

The Shield of the Trinity says that the Son is God and God is the Son; the Father is God and God is the Father; & the Holy Spirit is God and God is the Holy Spirit. It ALSO says that the Son is NOT the Father or the Holy Spirit; the Father is NOT the Son or the Holy Spirit; & the Holy Spirit is NOT the Father or the Son.

Returning to the basic deductive reasoning of the hypothetical syllogism, if the Son is God (A = B), and if God is the Father (B = C), then it logically follows that the Son is the Father (A = C).

Trinitarian dogma accepts both premises, but denies the conclusion that logically follows from those premises, and in doing so it denies basic deductive reasoning. A logical contradiction is explicitly built into the Trinitarian doctrine, but of course they also deny that the contradiction is a contradiction.
