Part 1. History of the Councils
Matters at Ariminum then had this speedy issue; for there was no disagreement there, but all of them with one accord both put into writing what they decided upon, and deposed the Arians.
12. Meanwhile the transactions in Seleucia the Rugged were as follows: it was in the month called by the Romans September, by the Egyptians Thoth, and by the Macedonians Gorpiæus, and the day of the month according to the Egyptians the 16th, upon which all the members of the Council assembled together. And there were present about a hundred and sixty; and whereas there were many who were accused among them, and their accusers were crying out against them, Acacius, and Patrophilus, and Uranius of Tyre, and Eudoxius, who usurped the Church of Antioch, and Leontius, and Theodotus, and Evagrius, and Theodulus, and George who has been driven from the whole world, adopt an unprincipled course. Fearing the proofs which their accusers had to show against them, they coalesced with the rest of the Arian party (who were mercenaries in the cause of irreligion for this purpose, and were ordained by Secundus, who had been deposed by the great Council), the Libyan Stephen, and Seras, and Polydeuces, who were under accusation upon various charges, next Pancratius, and one Ptolemy a Meletian. And they made a pretence of entering upon the question of faith, but it was clear they were doing so from fear of their accusers; and they took the part of the heresy, till at length they were divided among themselves. For, whereas those with Acacius and his fellows lay under suspicion and were very few, the others were the majority; therefore Acacius and his fellows, acting with the boldness of desperation, altogether denied the Nicene formula, and censured the Council, while the others, who were the majority, accepted the whole proceedings of the Council, except that they complained of the word 'Coessential,' as obscure and so open to suspicion. When then time passed, and the accusers pressed, and the accused put in pleas, and thereby were led on further by their irreligion and blasphemed the Lord, thereupon the majority of Bishops became indignant, and deposed Acacius, Patrophilus, Uranius, Eudoxius, and George the contractor, and others from Asia, Leontius, and Theodosius, Evagrius and Theodulus, and excommunicated Asterius, Eusebius, Augarus, Basilicus, Phœbus, Fidelius, Eutychius, and Magnus. And this they did on their non-appearance, when summoned to defend themselves on charges which numbers preferred against them. And they decreed that so they should remain, until they made their defence and cleared themselves of the offenses imputed to them. And after dispatching the sentence pronounced against them to the diocese of each, they proceeded to Constantius, the most irreligious Augustus, to report to him their proceedings, as they had been ordered. And this was the termination of the Council in Seleucia.
13. Who then but must approve of the conscientious conduct of the Bishops at Ariminum? Who endured such labour of journey and perils of sea, that by a sacred and canonical resolution they might depose the Arians, and guard inviolate the definitions of the Fathers. For each of them deemed that, if they undid the acts of their predecessors, they were affording a pretext to their successors to undo what they themselves then were enacting. And who but must condemn the fickleness of Eudoxius, Acacius, and their fellows, who sacrifice the honour due to their own fathers to partizanship and patronage of the Ario-maniacs? For what confidence can be placed in their acts, if the acts of their fathers be undone? Or how call they them fathers and themselves successors, if they set about impeaching their judgment? And especially what can Acacius say of his own master, Eusebius, who not only gave his subscription in the Nicene Council, but even in a letter signified to his flock, that that was true faith, which the Council had declared? For, if he explained himself in that letter in his own way, yet he did not contradict the Council's terms, but even charged it upon the Arians, that their position that the Son was not before His generation, was not even consistent with His being before Mary. What then will they proceed to teach the people who are under their teaching? That the Fathers erred? And how are they themselves to be trusted by those, whom they teach to disobey their Teachers? And with what eyes too will they look upon the sepulchres of the Fathers whom they now name heretics? And why do they defame the Valentinians, Phrygians, and Manichees, yet give the name of saint to those whom they themselves suspect of making parallel statements? Or how can they any longer be Bishops, if they were ordained by persons whom they accuse of heresy? But if their sentiments were wrong and their writings seduced the world, then let their memory perish altogether; when, however, you cast out their books, go and cast out their remains too from the cemeteries, so that one and all may know that they are seducers, and that you are parricides.
14. The blessed Apostle approves of the Corinthians because, he says, 'ye remember me in all things, and keep the traditions as I delivered them to you'; but they, as entertaining such views of their predecessors, will have the daring to say just the reverse to their flocks: 'We praise you not for remembering your fathers, but rather we make much of you, when you hold not their traditions.' And let them go on to accuse their own unfortunate birth, and say, 'We are sprung not of religious men but of heretics.' For such language, as I said before, is consistent in those who barter their Father.' fame and their own salvation for Arianism, and fear not the words of the divine proverb, 'There is a generation that curses their father', and the threat lying in the Law against such. They then, from zeal for the heresy, are of this obstinate temper; you, however, be not troubled at it, nor take their audacity for truth. For they dissent from each other, and, whereas they have revolted from their Fathers, are not of one and the same mind, but float about with various and discordant changes. And, as quarrelling with the Council of Nicæa, they have held many Councils themselves, and have published a faith in each of them, and have stood to none, nay, they will never do otherwise, for perversely seeking, they will never find that Wisdom which they hate. I have accordingly subjoined portions both of Arius's writings and of whatever else I could collect, of their publications in different Councils; whereby you will learn to your surprise with what object they stand out against an Ecumenical Council and their own Fathers without blushing.
