Again, I disagree. If one claims to be Christian (not talking about Trump here), and yet his life is completely filled with anti-Christian choices and acts–his or her faith comes into doubt. Again, the Lord Himself said those who call on His name might people He never knew.
However, with that said, if it were me or you, I’d tend to agree with you. In this case, we are talking about the Vicar of Christ. Do Catholics understand what that means? He holds the keys and he is the Pastor over the entire universal church on earth.
