Regardless, papal infallibility means he cannot issue a teaching which is incorrect.
Peter, by his actions, already issued a teaching which was incorrect.
I am not saying that the RCC is corrupt, but that this word of yours has no place in the Kingdom of Heaven.
How can you separate an action from a teaching ? Peter followed a spirit which was not the spirit of God through the Judaizing believers’ words, and thereby went astray, which then led the believers astray as well. Peter, your first pope, erred in thought and action, and led others to err in thought and action - and none of the “magisterium” John and James and who ever else was there - corrected him!!!
What man could say that he is inerrant? Even Paul said,
“For I am conscious of nothing against myself, yet I am not by this acquitted; but the one who examines me is the Lord.” meaning, he is capable of committing errors - even error in doctrine, if he was to get into the flesh, since ALL doctrinal error issues either from ignorance of from the flesh desiring to have attention and receive praise Gal 6:13.
But, if after this, you choose to keep your thoughts the same, that is not my issue; in the end, you belong to God - not me - and I need to move on.
God bless.
