Sainted Liberius the Confessor, Pope of Rome, entered upon the papal throne in the year 352, after the death of Pope Julius. Saint Liberius was a fervent proponent of Orthodoxy against the Arian heresy and a defender of Saint Athanasias of Alexandria (Comm. 2 May). The emperor Constantius (337-361), inclining to side with the Arians, was not able to compel Saint Liberius to make a judgement against Saint Athanasias nor therefore against Orthodoxy. For such intransigence he was sent off to prison in Beroeia (Thrace), but was soon returned back on the insistent demands of the Roman people. Before his return, they summoned Saint Liberius to the Third Sirmian Semi-Arian Council, where they forced him to undersign the deliberations of the Council. Holy Pope Liberius afterwards deeply repented of this, and toiled much at Rome for the affirmation of Orthodoxy. He died peacefully in the year 366.
