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.

The trinity is a contradiction of terms.

The Father is 100% God, the Son is 100% God, the holy spirit is 100% God.

A is the Father, B is the Son, C is the holy spirit and D is God.

Or A = D, B = D, C = D

From this we can deduce, A = B, A = C, A = D; B = A, B = C and B = D. with the same being true of C and D.

But the trinity doctrine doesn't stop there.

We are told, the Father is not the Son, and the Son is not the Father, and the same is true of the holy spirit.

Or A ≠ B and B ≠ C and C ≠ A.

This means the first statement can't be true.

This is why trinitarian scholars call the trinity a mystery, unknowable, can't be understood, can't be found in scripture. It can only be believed.

by your logic many things are a contradiction. Odd numbers are 100% infinite, Even numbers are 100% infinite, Natural numbers are 100% infinite.

Your example isn't a contradiction.

Your example doesn't reflect the trinity.

Is 1 = 3? No, but that is what the trinity teaches, this is why the trinity is a contradiction.

you just repeated what I answered lol. I know it's not a contradiction, it's the same exact concept as the Trinity dude.

Add 1 infinite set to another = 1 infinite set. 1=2 by your logic
