Part 1. History of the Councils
Reason why two Councils were called. Inconsistency and folly of calling any; and of the style of the Arian formularies; occasion of the Nicene Council; proceedings at Ariminum; Letter of the Council to Constantius; its decree. Proceedings at Seleucia; reflections on the conduct of the Arians.
1. Perhaps news has reached even yourselves concerning the Council, which is at this time the subject of general conversation; for letters both from the Emperor and the Prefects were circulated far and wide for its convocation. However, you take that interest in the events which have occurred, that I have determined upon giving you an account of what I have seen myself, and accurately ascertained, which may save you from the suspense attendant on the reports of others; and this the more, because there are parties who are in the habit of misrepresenting what has happened. At Nicæa then, which had been fixed upon, the Council has not met, but a second edict was issued, convening the Western Bishops at Ariminum in Italy, and the Eastern at Seleucia the Rugged, as it is called, in Isauria. The professed reason of such a meeting was to treat of the faith touching our Lord Jesus Christ; and those who alleged it, were Ursacius, Valens, and one Germinius from Pannonia; and from Syria, Acacius, Eudoxius, and Patrophilus of Scythopolis. These men who had always been of the Arian party, and 'understood neither how they believe or whereof they affirm,' and were silently deceiving first one and then another, and scattering the second sowing of their heresy, influenced some who seemed to be somewhat, and the Emperor Constantius among them, being a heretic, on some pretence about the Faith, to call a Council; under the idea that they should be able to put into the shade the Nicene Council, and prevail upon all to turn round, and to establish irreligion everywhere instead of the Truth.
2. Now here I marvel first, and think that I shall carry every sensible man whatever with me, that, whereas a General Council had been fixed, and all were looking forward to it, it was all of a sudden divided into two, so that one part met here, and the other there. However, this was surely the doing of Providence, in order in the respective Councils to exhibit the faith without guile or corruption of the one party, and to expose the dishonesty and duplicity of the other. Next, this too was on the mind of myself and my true brethren here, and made us anxious, the impropriety of this great gathering which we saw in progress; for what pressed so much, that the whole world was to be put in confusion, and those who at the time bore the profession of clergy, should run about far and near, seeking how best to learn to believe in our Lord Jesus Christ? Certainly if they were believers already, they would not have been seeking, as though they were not. And to the catechumens, this was no small scandal; but to the heathen, it was something more than common, and even furnished broad merriment, that Christians, as if waking out of sleep at this time of day, should be enquiring how they were to believe concerning Christ; while their professed clergy, though claiming deference from their flocks, as teachers, were unbelievers on their own showing, in that they were seeking what they had not. And the party of Ursacius, who were at the bottom of all this, did not understand what wrath they were storing up against themselves, as our Lord says by His saints, 'Woe unto them, through whom My Name is blasphemed among the Gentiles'; and by His own mouth in the Gospels, 'Whoso shall offend one of these little ones, it were better for him that a millstone were hanged about his neck and that he were drowned in the depth of the sea, than,' as Luke adds, 'that he should offend one of these little ones'.
3. What defect of teaching was there for religious truth in the Catholic Church, that they should enquire concerning faith now, and should prefix this year's Consulate to their profession of faith? For Ursacius and Valens and Germinius and their friends have done what never took place, never was heard of among Christians. After putting into writing what it pleased them to believe, they prefix to it the Consulate, and the month and the day of the current year; thereby to show all sensible men, that their faith dates, not from of old, but now, from the reign of Constantius; for whatever they write has a view to their own heresy. Moreover, though pretending to write about the Lord, they nominate another master for themselves, Constantius, who has bestowed on them this reign of irreligion; and they who deny that the Son is everlasting, have called him Eternal Emperor; such foes of Christ are they in addition to irreligion. But perhaps the dates in the holy Prophets form their excuse for the Consulate; so bold a pretence, however, will serve but to publish more fully their ignorance of the subject. For the prophecies of the saints do indeed specify their times (for instance, Isaiah and Hosea lived in the days of Uzziah, Jotham, Ahaz, and Hezekiah; Jeremiah in the days of Josiah; Ezekiel and Daniel prophesied under Cyrus and Darius; and others in other times); yet they were not laying the foundations of divine religion; it was before them, and was always, for before the foundation of the world God prepared it for us in Christ. Nor were they signifying the respective dates of their own faith; for they had been believers before these dates. But the dates did but belong to their own preaching. And this preaching spoke beforehand of the Saviour's coming, but directly of what was to happen to Israel and the nations; and the dates denoted not the commencement of faith, as I said before, but of the prophets themselves, that is, when it was they thus prophesied. But our modern sages, not in historical narration, nor in prediction of the future, but, after writing, 'The Catholic Faith was published,' immediately add the Consulate and the month and the day, that, as the saints specified the dates of their histories, and of their own ministries, so these may mark the date of their own faith. And would that they had written, touching 'their own ' (for it does date from today); and had not made their essay as touching 'the Catholic,' for they did not write, 'Thus we believe,' but 'the Catholic Faith was published.'
4. The boldness then of their design shows how little they understand the subject; while the novelty of their phrase matches the Arian heresy. For thus they show, when it was they began their own faith, and that from that same time present they would have it proclaimed. And as according to the Evangelist Luke, there 'was made a decree' concerning the taxing, and this decree before was not, but began from those days in which it was made by its framer, they also in like manner, by writing, 'The Faith is now published,' showed that the sentiments of their heresy are novel, and were not before. But if they add 'of the Catholic Faith,' they fall before they know it into the extravagance of the Phrygians, and say with them, 'To us first was revealed,' and 'from us dates the Faith of Christians.' And as those inscribe it with the names of Maximilla and Montanus, so do these with 'Constantius, Master,' instead of Christ. If, however, as they would have it, the faith dates from the present Consulate, what will the Fathers do, and the blessed Martyrs? Nay, what will they themselves do with their own catechumens, who departed to rest before this Consulate? How will they wake them up, that so they may obliterate their former lessons, and may sow in turn the seeming discoveries which they have now put into writing? So ignorant they are on the subject; with no knowledge but that of making excuses, and those unbecoming and unplausible, and carrying with them their own refutation.
