I see you flunked basic multiplication.
If you took 1, 1, 1, you think the answer is always a formula "3", eh?
Well, what is 1 x 1 x 1?
One needs to assume 1 = 1 = 1 for that equation to work. That is, they are identical in all respects.
If they were so in the case of the trinity, then why did Jesus pray to God? Being identical would imply that the inherent properties of each entity is identical to the other. There is nothing one of the entities could have possessed, which the other didn’t, which was remedied through one of the entities praying to the other. Each one would have been identical intimately to such an extent, that praying is meaningless.
