About this episode

This episode discusses Liberius, the first pope not recognized as a saint and his controversial legacy regarding papal infallibility.

Liberius (352-366) is not only the first pope in history not to be considered a saint in the Catholic Church, but is also often used by anti-Catholic critics to argue against papal infallibility - since he allegedly signed documents in favor of Arianism under duress from the emperor.
