Straight from the Bible:
Papacy/infallibility
Mt 16:18-19 ... Jesus gives Peter primacy: rock, keys, binding and loosing.
Is 22:22; Rev 1:18 ... keys as symbol of authority.
Jn 21:17 ... “feed my sheep”
Mt 10:1-4; Mk 3:16-19; Lk 6:14-16; Acts 1:13; Lk 9:32 ... Peter always mentioned first, as foremost apostle.
Mt 18:21; Mk 8:29; Lk 12:41; Jn 6:68-69 ... Peter speaks for the apostles.
Acts 2:14-40 ... Pentecost: Peter who first preached.
Acts 3:6-7 ... Peter worked first healing.
Acts 10:46-48 ... Gentiles to be baptized revealed to Peter.
Jn 1:42 ... Simon is Cephas (Aramaic: Kepha for rock).
Lk 22:31-32 ... “Simon ... strengthen your brethren”.
Lk 10:1-2, 16; Jn 13:20; 2 Cor 5:20; Gal 4:14; Acts 5:1-5 ... “vicars” (substitutes) of Christ.
Mk 6:20; Lk 1:70,2:23;
Rom 12:1; Act 3:21, 1 Cor 7:14; Eph 3:5; Col 1:22 ... humans can be holy (“call no one holy”).
Rather than a machine gun approach, let’s review each and every passage in context to see if it supports your position. Do one at a time. Start with mandatory priestly celibacy. Show me ONE passage in the Bible which requires celibacy as a condition for serving in the priesthood and we’ll take it from there.
