This attack by Hilary and his friends was, according to him, the attempt of a handful of men to break up the unity attained by the labours of that great assembly of six hundred bishops. He declared his firm assent to all its decisions; every heresy that it had condemned he condemned. He sent with his address a copy of the Acts of the Council, and begged the Emperor to have them read to him. Its language would convince him that Hilary and Eusebius, bishops long deposed, were merely plotting universal schism. This, with his own account of the proceedings before the commission and a short statement of his belief, forms his appeal to the Emperor. It was composed with great skill, and was quite unanswerable. His actual possession of the see, the circumstances of the time, the very doctrine of the Church—for only a Council could undo what a Council had done—rendered his position unassailable. And if he was in the right, Hilary and his colleague were in the wrong. Nothing but success could have saved them from the humiliation to which they were now subjected, of being expelled from Milan and bidden to return to their homes, while the Emperor publicly recognised Auxentius by receiving the Communion at his hands. Yet morally they had been in the right throughout.
The strong legal position of Auxentius and the canons of that imposing Council of six hundred bishops behind which he screened himself had been obtained by deliberate fraud and oppression. He and his creed could not have, and did not deserve to have, any stability. Yet Valentinian was probably in the right, even in the interests of truth, in refusing to make a martyr of Auxentius. There would have been reprisals in the East, where the Catholic cause had far more to lose than had Arianism in the West; and general considerations of equity and policy must have inclined him to allow the Arian to pass the remainder of his days in peace. But we cannot wonder that Hilary failed to appreciate such reasons. He had thrown himself with all his heart into the attack, and risked in it his public credit as bishop and confessor and first of Western theologians. Hence his published account of the transaction is tinged with a pardonable shade of personal resentment. It was, indeed, necessary that he should issue a statement. The assault and the repulse were rendered conspicuous by time and place, and by the eminence of the persons engaged; and it was Hilary’s duty to see that the defeat which he had incurred brought no injury upon his cause. He therefore addressed a public letter ‘to the beloved brethren who abide in the Faith of the fathers and repudiate the Arian heresy, the bishops and all their flocks.’ He begins by speaking of the blessings of peace, which the Christians of that day could neither enjoy nor promote, beset as they were by the forerunners of Antichrist, who boasted of the peace, in other words of the harmonious concurrence in blasphemy, which they had brought about.
They bear themselves not as bishops of Christ but as priests of Antichrist. This is not random abuse, but sober recognition of the fact, stated by St. John, that there are many Antichrists. For these men assume the cloak of piety, and pretend to preach the Gospel, with the one object of inducing others to deny Christ. It was the misery and folly of the day that men endeavoured to promote the cause of God by human means and the favour of the world. Hilary asks bishops, who believe in their office, whether the Apostles had secular support when by their preaching they converted the greater part of mankind. They were not adorned with palace dignities; scourged and fettered, they sang their hymns. It was in obedience to no royal edict that Paul gathered a Church for Christ; he was exposed to public view in the theatre. Nero and Vespasian and Decius were no patrons of the Church; it was through their hatred that the truth had thriven. The Apostles laboured with their hands and worshipped in garrets and secret places, and in defiance of senate or monarch visited, it might be said, every village and every tribe. Yet it was these rebels who had the keys of the Kingdom of Heaven; the more they were forbidden, the more they preached, and the power of God was made manifest. But now the Faith finds favour with men.
The Church seeks for secular support, and in so doing insults Christ by the implication that his support is insufficient. She in her turn holds out the threat of exile and prison. It was her endurance of these that drew men to her; now she imposes her faith by violence. She craves for favours at the hands of her communicants; once it was her consecration that she braved the threatenings of persecutors. Bishops in exile spread the Faith; now it is she that exiles bishops. She boasts that the world loves her; the world’s hatred was the evidence that she was Christ’s. The ruin is obvious which has fallen upon the Church. The time of Antichrist, disguised as an angel of light, has come. The true Christ is hidden from almost every mind and heart. Antichrist is now obscuring the truth that he may assert falsehood hereafter. Hence the conflicting opinions of the time, the doctrine of Arius and of his heirs, Valens, Ursacius, Auxentius and their fellows. Their preaching of novelties concerning Christ is the work of Antichrist, who is using them to introduce his own worship. This is proved by a statement of their minimising and prevaricating doctrine, which has, however, made no impression upon the guileless and well-meaning laity. Then comes Hilary’s account of his proceedings at Milan, strongly coloured by the intensity of his feelings.
