I’d say that is why a mormon baptism is invalid, to anyone, mormonism is all based on lies and something based on a lie has no truth in it. I could baptize my dog and have about the same effect.
The revoked baptism is from the POV of a mormon, so that was a response to Zerinus. His church would excommunicate me the minute any mormon ratted out that I had indeed done such a thing. So, my mormon baptism would be revoked in their eyes anyway, so what is it to them if I am baptized somewhere else and whether or not that somewhere else sees my revoked baptism as valid? From their POV I would no longer be baptized anyway.
In short, Zerinus is complaining about a Catholic POV that has no bearing whatsoever to his own beliefs. I don’t even know WHY he would even bother posting about it. it is no problem to him.
From a Catholic POV I understand the “issues”, and were I to join the Catholic church I would want to be baptized as a Catholic, because as it is, the only thing that I find valuable in my mormon baptism is that it was done by my father. But that doesn’t have anything to do with theology, more just a strong sentiment re: someone I love.
But thanks for your prayers. I think I seem more lost than I am. Or maybe was. lol. I am headed into RCIA, and went to a pre-RCIA where Mass was explained and a theological tour of the Cathedral. It was intensely beautiful.

And I have good conversations with a Catholic friend who will be my RCIA sponsor (hi).

Life is good and getting better and I am smiling.
