“Go to a local Catholic Church and be baptized by a real priest or better yet, a Franciscan monk.”
A real priest? So, would you have us to believe that Protestant ministers aren’t qualified to perform valid baptisms?
The validity of a baptism depends on the believer’s faith in God and his need to obey God’s commands (such as baptism as a requisite for salvation), not the “realness” of the person doing the baptism.
Just suppose that a “real” priest performed a baptism, and then later that day did some heinous act; was the baptism of the believer invalidated by the priest’s sinful act? No, of course not! The validity of baptism comes from the believer’s faith, not the priest’s authority.
The mandate was given not to any “pastor” but to Peter and his successors and the Church founded on the rock “Petrus” whose name was changed by Christ Himself.
