GOD speaks infallibly through HIS WORD ALONE - He would never use man to speak infallible for Him - because man is INCAPABLE of it!
You are under compulsive to believe what the Vatican says - so you can't entertain that the pope's 'self proclaimed' infallibility is bogus. You are stuck - so discussing it with you is equivalent as discussing it with a stone wall.
But it shows those of us who know they Truth, there will be gnashing of teeth when those who believe in man's infallibility are presented with 'Why did you believe man could every be infallible? Clearly you never KNEW ME'.
But it's written down now, you were told the Truth and believed it not. And guess what - it wasn't from the one 'claiming infallibility' because he still has his hooks in you - he has no plans on letting you go. However, many have escaped. 'Man's infallibility' is the height of pride - so we know who is behind that.
Yes, he does. But the WORD is much more that Scripture. God has always chosen men to speak through and continues to do so.
