So, how do you know that, my arrogant friend? I’m going by the catechism 1257.
You just can't help yourself can you?
But yet, proving once again my observation of Roman Catholics....they are usually, though not always, the first to resort to the personal attack and/or profanity when things go against them.
Your CCC is trying to have it both ways....either baptism is a requirement of salvation or it isn't.
Further, if it's going to be baptism then it must be baptism by immersion....something not always practiced in Roman Catholicism.
