Constantius, ordered Liberius into exile in 356 giving him, then, three days to comply. He was ordered into banishment to Beroea, in Thrace; Beroea (Thrace). He sent expensive presents, too, if he were to accept the Arian position but were refused. He sent him, indeed, five hundred pieces of gold "to bear his charges" but Liberius refused them, saying, he might bestow them on his flatters; as he did also a like present from the empress, bidding the messenger learn to believe in Christ, and not to persecute the Church of God. Attempts were made to leave the presents in The Church, but Liberius threw them out. Constantius hereupon sent for him under a strict guard to Milan, where, in a conference recorded by Theodoret, he boldly told Constantius that Athanasius had been acquitted at Sardica, and his enemies proved calumniators (see: "calumny") and impostors, and that it was unjust to condemn a person who could not be legally convicted of any crime. The emperor was reduced to silence on every article, but being the more out of patience, ordered him into banishment. Liberius went into exile. Constantius, after two years went to Rome to celebrate the twentieth year of his reign. The ladies joined in a petition to him that he would restore Liberius. He assented, upon condition that he should comply with the bishops, then, at court. He subscribed the condemnation of Athanasius, and a confession or creed which had been framed by the Arians at Sirmium. And he no sooner had recovered his see that he declared himself for the Creed of Niceae, as Theodoret testifies. (Theodoret, Hist. lib. ii. c. 17.). The Emperor knew what he wanted people to believe. So did the bishops at his court. Athanasius stuck by the orthodox creed. Constantius was an avowed Arian, became sole ruler in 350, at the death of his brother, Constans.
How much warning was Liberius given before his freedom?
