In his office of supreme pontiff in the old pagan religion, which he held by virtue of being emperor of Rome, Constantine may naturally have supposed that the supreme headship of the religion he had protected and the Church he had elevated fell to him for the same reason; and with it the right to reconcile differences, compose factions, and determine what should be the orthodox faith. At any rate we find him acting somewhat in this capacity. When contending church parties appealed to him, he at first was indifferent to their disputes, and tried to shame them into harmony by referring to the conduct of the Greek philosophers, who never discussed difficult questions before ignorant multitudes; who could "maintain their arguments without losing their temper; and assert their freedom without violating any friendship." [127] His efforts at reconciling the differences that arose among Christians over what is known as the Arian controversy were of no avail; and after six years of bitter strife, the emperor summoned the bishops of the Church to Nicea in Bithynia. After long deliberation Arianism was condemned, and orthodox Christianity was established by decree of the council, ratified by the emperor, to which all Christians must conform. Those who resisted the divine judgment of the synod must prepare themselves for immediate exile. [128] How effectual the argument, "belief or banishment," even among the bishops at the council, was, may be determined from the fact that "the opposition to the decision of the council was almost {LXVIII} instantly reduced from seventeen to two." [129] In his zeal to enforce orthodoxy the emperor forgot his former moderation, and in 326 A.D.--the year following the council of Nicea--he issued a general edict against heretics, in which, after condemning his own past forbearance as occasioning men's being seduced, he says to the various heretical parties: Wherefore, since this your pernicious wickedness is no longer to be endured, we by this present law command you, that you no more presume to meet together. And we have given orders that all those places where you are wont to hold assemblies should be taken away. Yea, our concern for this matter is such, that we not only forbid you to assemble to any public place; but we likewise forbid all assemblies of your foolish superstition in private houses, and in all private places whatever. All of you, therefore, who have any sincere love of truth, come to the Catholic church. And that this remedy may have its full effect, we ordain that all your superstitious conventicles, I mean oratories of all heretics, if it be fit to call such houses oratories, be forthwith taken away, and without any opposition delivered to the Catholic church: and that the rest of your places be adjudged to the public.
