Historia Arianorum

When the Bishops heard this they were utterly amazed, and stretching forth their hands to God, they used great boldness of speech against him teaching him that the kingdom was not his, but God's, who had given it to him, Whom also they bid him fear, lest He should suddenly take it away from him. And they threatened him with the day of judgment, and warned him against infringing Ecclesiastical order, and mingling Roman sovereignty with the constitution of the Church, and against introducing the Arian heresy into the Church of God.

But he would not listen to them, nor permit them to speak further, but threatened them so much the more, and drew his sword against them, and gave orders for some of them to be led to execution; although afterwards, like Pharaoh, he repented. The holy men therefore shaking off the dust, and looking up to God, neither feared the threats of the Emperor, nor betrayed their cause before his drawn sword; but received their banishment, as a service pertaining to their ministry. And as they passed along, they preached the Gospel in every place and city, although they were in bonds, proclaiming the orthodox faith, anathematizing the Arian heresy, and stigmatizing the recantation of Ursacius and Valens.

But this was contrary to the intention of their enemies; for the greater was the distance of their place of banishment, so much the more was the hatred against them increased, while the wanderings of these men were but the heralding of their impiety. For who that saw them as they passed along, did not greatly admire them as Confessors, and renounce and abominate the others, calling them not only impious men, but executioners and murderers, and everything rather than Christians?
