Salvation, I think one is baptized a Christian, not a Catholic, and I am a baptized Catholic to contradict myself for a second there.
Although not all denominations recognize the baptisms of others, still I think my original point holds.
Hey, at least that’s what my mom told me.
The Catholic Church does recognize other churches baptisms if they are done correctly.
However, the mark on one’s soul from Baptism, Confirmation and Holy Orders, I believe is a Catholic belief. Once a Catholic always a Catholic even if they are inactive.
