The case of Galatians 2:11-14…
The “St. Paul resisted St. Peter to his Face” Objection
Time and again we hear from those we call Semi-Traditionalists the argument that a Pope can lead the faithful astray into errors against the Faith through the exercise of his non-infallible Magisterium; and when that happens, it is then the right and the duty of the victim faithful to resist him, clinging to “Tradition”.
Those who defend this position often point to an incident that occurred between St. Paul and St. Peter recorded in Galatians 2:11-14, as supposed historical precedent for an error-teaching Pope being corrected and resisted by his inferiors.
