It was a time when new combinations of parties were being formed. Arianism was shewing itself openly, as it had not dared to do since Nicæa. In 357 Hilary’s adversaries, Ursacius and Valens, in a Synod at Sirmium, published a creed which was Arian without concealment; it was, indeed, as serious a blow to the Emperor’s policy of compromise as anything that Athanasius or Hilary had ventured. But it was the work of friends of the Emperor, and shewed that, for the moment at any rate, the Court had been won over to the extreme party. But the forces of Conservatism were still the strongest. Within a few months, early in 358, the great Asiatic prelates, soon to be divided over the question of the Godhead of the Holy Spirit but still at one, Basil of Ancyra, Macedonius and others, met at Ancyra and repudiated Arianism while ignoring, after their manner, the Nicene definition. Then their delegates proceeded to the Court, now at Sirmium, and won Constantius back to his old position. Ursacius and Valens, who had no scruples, signed a Conservative creed, as did the weak Liberius of Rome, anxious to escape from an exile to which he had been consigned soon after the banishment of Hilary. It was a great triumph to have induced so prominent a bishop to minimise—we cannot say that he denied—his own belief and that of the Western churches. And the Asiatic leaders were determined to have the spoils of victory. Liberius, of course, was allowed to return home, for he had proved compliant, and the Conservatives had no quarrel with those who held the homoousion. But the most prominent of the Arian leaders, those who had the courage of their conviction, to the number, it is said, of seventy, were exiled. It is true that Constantius was quickly persuaded by other influences to restore them; but the theological difference was embittered by the sense of personal injury, and further conflicts rendered inevitable between Conservatives and Arians.
