No you can't....you can be baptized in a Lutheran church, an Episcopal church, a Baptist church, in a hospital, in a bedroom right after birth if necessary, on a bus, in an auto....it doesn't matter at all where you were baptized nor by who....I can do it, you can do it, the Pope can do it...it is all the same....If you were validly baptized, you were baptized Catholic....there can be no other way.
They arent getting that it is the act of baptism alone...not the label applied to the act baptism after the fact.
If I were you, I'd ask for a refund on your Theology degree....it's defective.
