Jerome (347-420): (Pope) Liberius Subscribed to Heretical Doctrine

Liberius was ordained the 34th bishop of the Roman church, and when he was driven into exile for the faith, all the clergy took an oath that they would not recognize any other bishop. But when Felix was put in his place by the Arians, a great many foreswore themselves; but at the end of the year they were banished, and Felix too; for Liberius, giving in to the irksomeness of exile and subscribing to the heretical and false doctrine, made a triumphal entry into Rome.
