I was a Confessor at the first, when a persecution arose in the time of your grandfather Maximian; and if you shall persecute me, I am ready now, too, to endure anything rather than to shed innocent blood and to betray the truth. But I cannot approve of your conduct in writing after this threatening manner. Cease to write thus; adopt not the cause of Arius, nor listen to those in the East, nor give credit to Ursacius, Valens and their fellows. For whatever they assert, it is not on account of Athanasius, but for the sake of their own heresy. Believe my statement, O Constantius, who am of an age to be your grandfather. I was present at the Council of Sardica, when you and your brother Constans of blessed memory assembled us all together; and on my own account I challenged the enemies of Athanasius, when they came to the church where I abode, that if they had anything against him they might declare it; desiring them to have confidence, and not to expect otherwise than that a right judgment would be passed in all things. This I did once and again, requesting them, if they were unwilling to appear before the whole Council, yet to appear before me alone; promising them also, that if he should be proved guilty, he should certainly be rejected by us; but if he should be found to be blameless, and should prove them to be calumniators, that if they should then refuse to hold communion with him, I would persuade him to go with me into the Spains. Athanasius was willing to comply with these conditions, and made no objection to my proposal; but they, altogether distrusting their cause, would not consent. And on another occasion Athanasius came to your Court, when you wrote for him, and his enemies being at the time in Antioch, he requested that they might be summoned either altogether or separately, in order that they might either convict him, or be convicted, and might either in his presence prove him to be what they represented, or cease to accuse him when absent. To this proposal also you would not listen, and they equally rejected it. Why then do you still give ear to them that speak evil of him? How can you endure Valens and Ursacius, although they have retracted and made a written confession of their calumnies? For it is not true, as they pretend, that they were forced to confess; there were no soldiers at hand to influence them; your brother was not cognizant of the matter. No, such things were not done under his government, as are done now; God forbid. But they voluntarily went up to Rome, and in the presence of the Bishop and Presbyters wrote their recantation, having previously addressed to Athanasius a friendly and peaceable letter. And if they pretend that force was employed towards them, and acknowledge that this is an evil thing, which you also disapprove of; then do you cease to use force; write no letters, send no Counts; but release those that have been banished, lest while you are complaining of violence, they do but exercise greater violence. When was any such thing done by Constans? What Bishop suffered banishment? When did he appear as arbiter of an Ecclesiastical trial? When did any Palatine of his compel men to subscribe against any one, that Valens and his fellows should be able to affirm this? Cease these proceedings, I beseech you, and remember that you are a mortal man. Be afraid of the day of judgment, and keep yourself pure thereunto. Intrude not yourself into Ecclesiastical matters, neither give commands unto us concerning them; but learn them from us. God has put into your hands the kingdom; to us He has entrusted the affairs of His Church; and as he who would steal the empire from you would resist the ordinance of God, so likewise fear on your part lest by taking upon yourself the government of the Church, you become guilty of a great offence. It is written, “Render unto Cæsar the things that are Cæsar’s, and unto God the things that are God’s.” Neither therefore is it permitted unto us to exercise an earthly rule, nor have you, Sire, any authority to burn incense. These things I write unto you out of a concern for your salvation. With regard to the subject of your letters, this is my determination; I will not unite myself to the Arians; I anathematize their heresy. Neither will I subscribe against Athanasius, whom both we and the Church of the Romans and the whole Council pronounced to be guiltless. And yourself also, when you understood this, sent for the man, and gave him permission to return with honour to his country and his Church. What reason then can there be for so great a change in your conduct? The same persons who were his enemies before, are so now also; and the things they now whisper to his prejudice (for they do not declare them openly in his presence), the same they spoke against him, before you sent for him; the same they spread abroad concerning him when they come to the Council. And when I required them to come forward, as I have before said, they were unable to produce their proofs; had they possessed any, they would not have fled so disgracefully. Who then persuaded you so long after to forget your own letters and declarations? Forbear, and be not influenced by evil men, lest while you act for the mutual advantage of yourself and them, you render yourself responsible. For here you comply with their desires, hereafter in the judgment you will have to answer for doing so alone. These men desire by your means to injure their enemy, and wish to make you the minister of their wickedness, in order that through your help they may sow the seeds of their accursed heresy in the Church. Now it is not a prudent thing to cast one’s self into manifest danger for the pleasure of others. Cease then, I beseech you, O Constantius, and be persuaded by me. These things it becomes me to write, and you not to despise.’
