Yes, and it’s whoever follows the teachings of Jesus and the Apostles. The Popes in the 14 and 1500s and Pope Frank are NOT recipients of the authority of Christ.
Should anyone claim authority that he doesn’t have, specifically by contradicting Jesus and the Apostles... well Paul in Galatians was rather graphic about what they should do to themselves.
What about good Popes like Benedict XVI?
The Catholic Church has had bad Popes before and is still here.
The Church will survive.
