When Constantine stood out before the world as the patron of the gospel, he felt bound to settle the question of Arianism. In some ways he was well qualified for the task. There can be no doubt of his ability and earnestness, or of his genuine interest in Christianity. In political skill he was an overmatch for Diocletian, and his military successes were unequalled since the triumph of Aurelian. The heathens saw in him the restorer of the Empire, the Christians their deliverer from persecution. Even the feeling of a divine mission, which laid him so open to flattery, gave him also a keen desire to remedy the social misery around him; and in this he looked for help to Christianity. Amidst the horrors of Diocletian's persecution a conviction grew upon him that the power which fought the Empire with success must somehow come from the Supreme. Thus he slowly learned to recognise the God of the Christians in his father's God, and in the Sun-god's cross of light to see the cross of Christ. But in Christianity itself he found little more than a confirmation of natural religion. Therefore, with all his interest in the churches, he could not reach the secret of their inner life. Their imposing monotheism he fully appreciated, but the person of the Lord was surely a minor question. Constantine shared the heathen feelings of his time, so that the gospel to him was only a monotheistic heathenism. Thus Arianism came up to his idea of it, and the whole controversy seemed a mere affair of words. [Sidenote: His view of the controversy.] But if he had no theological interest in the question, he could not overlook its political importance. Egypt was always a difficult province to manage; and if these Arian songs caused a bloody tumult in Alexandria, he could not let the Christians fight out their quarrels in the streets, as the Jews were used to do. The Donatists had given him trouble enough over a disputed election in Africa, and he did not want a worse than Donatist quarrel in Egypt. Nor was the danger confined to Egypt; it had already spread through the East. The unity of Christendom was at peril, and with it the support which the shattered Empire looked for from an undivided church. The state could treat with a definite organisation of churches, but not with miscellaneous gatherings of sectaries. The question must therefore be settled one way or the other, and settled at once. Which way it was decided mattered little, so that an end was made of the disturbance. [Sidenote: His first attempt to settle it.]
