Peter was not impeccable, he made human mistakes.
But as Pope when acting on faith and morals, he was guided by the Holy Spirit and thus was in falliable, as is the Magisterium and Pope of today when ruling on major items of faith and morals. Some people don’t realize that.
Some people don’t even know how to spell it.
“But as Pope when acting on faith and morals, he was guided by the Holy Spirit and thus was in falliable,”
Well, he was called out and corrected for acting on faith and morals. Please understand I am not disliking Peter (Cephas), but am asserting he is not a Pope. He was “just” an apostle, a great thing to be sure, but not a Pope.
“When Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he used to eat with the Gentiles. But when they arrived, he began to draw back and separate himself from the Gentiles because he was afraid of those who belonged to the circumcision group. The other Jews joined him in his hypocrisy, so that by their hypocrisy even Barnabas was led astray.”
