Can then Catholics then acknowledge this verse from the same John:
30 Many other signs also did Jesus in the sight of his disciples, which are not written in this book. 31 But these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name. Douay-Rheims 1899 American Edition (DRA) Public Doman
All the latter day proclamations of Rome that require belief for salvation fall outside this admonition from John. PV/IC/Papal infallibility etc are all additions to the salvation message. As such they are another Gospel, just like Paul indicated.
30 Many other signs also did Jesus in the sight of his disciples, which are not written in this book. 31 But these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name. Douay-Rheims 1899 American Edition (DRA) Public Doman
I don't think that one is included on the list - Rome's 50 Approved Scriptures For Minions. As best as I can tell from these threads, most of the OT and all of Paul's writing is also verboten to the RC masses.
On a more serious note, I think verse 30 is just as important as 31. God inspired the writers to ONLY record specific miracles, events, teaching, and the Word of God (Jesus only spoke what the Father said - John 12:49-50). We can be assured everything needful to our Salvation is included in the Gospels. Once you BELIEVE, turn to Romans through Thessalonians to see who you are IN CHRIST.
