We have to consider how, in the first three centuries, all this was actually carried out; and we shall best do so by placing ourselves at the remarkable point of history, the convocation of the Nicene Council in the year 325, and by summing up the result of the long conflict which preceded that event, as regards these three particulars. The Nicene Council was convoked to terminate the question which Arius had raised as to the Godhead of our Lord. It was the remedy of the Emperor Constantine for the malady which had broken out in the Church. He had just become, by the death of Licinius, sole ruler of the Roman world. Though not yet a Christian by the reception of baptism, he had conceived the highest veneration for the Christian Church. There can be no doubt that he trusted, by means of its spiritual unity, to weld together on a firmer basis the shaken fabric of imperial Rome. Thus he looked with much sorrow and no little perplexity upon the rise of a heresy in the important Church of Alexandria; and when its bishop, in spite of his great authority, as the head of the second Church in the world, which by a most powerful organisation governed the three secular provinces of Egypt, Libya, and Pentapolis, was unable to expel the mischief, he urged the convocation of a General Council. He convoked it, so far as a secular prince could do so, by giving all the assistance which the public authority could render in a State politically absolute; for he not only invited the bishops to attend, but ordered that they should travel free of cost at the public expense. Pope Sylvester, on his side, assented; he sent his legates to the Council, where they alone represented the whole West, and so by his assent and by the mission of his legates gave the Council its œcumenical character. By this act the Emperor, who, it should be borne in mind, was still the Pontifex Maximus of heathen worship, and the official head of the old State religion, recognised the Church of Christ as a spiritual kingdom, possessing a doctrine of which it was the sole judge and bearer; recognised in its bishops the representatives of the various powers placed by Christ, its Founder, therein, as those who bore throughout his empire a priesthood, and exercised a spiritual rule and jurisdiction, and preached a doctrine all bound together in one whole; who, moreover, in virtue of this triple character, which came upon them from above, by the institution of Christ and through the medium of consecration, which is to say, by the force of a divine unction, and not by any human authority, represented a people which likewise was spread everywhere, while it was one likewise in virtue of a divine consecration, baptism in the threefold name of God.
