read Ephesians 4:5 and then re-read your post and then tell me who is ignorant of the Scriptures.
there is a reason when the Catholic Bishops gathered in Nicea, they said “ we acknowledge ONE baptism for the forgiveness of sins”.
Exactly. And that is why the baptism they acknowledged (water) was completely wrong. As is everything the RCC attempts to do Scripturally. And hence, the need for doctrines, traditions, blah, blah.
