Before speaking of Theodoric's relations with the Church, which were a matter of politics, and had to be considered by him on general grounds of policy, it is necessary to speak of the relations between the Church and the Emperor, for the latter affected the former. There were always difficulties, active or latent, between the Roman Church and the Empire. There was jealousy between old Rome and new Constantinople. There was misunderstanding between the Latin and Greek mind. There was friction between Papal and Imperial authority. These troubles will appear more clearly as we proceed. At this time it is only necessary to say that during the first thirty years of Theodoric's reign, his period of success and prosperity, there was discord between Pope and Emperor, a kind of schism. The Byzantine Emperors, often men of cultivation, living in the most civilized city of the world, interested themselves in theology, and liked nothing better than to tinker with the Faith. To this, also, they were pushed by political needs. Their subjects were divided into the orthodox and the heterodox; and this diversity of belief was always a menace to political unity. To heal the breach, the reigning Emperor devised a scheme of compromise, a _via media_, on which he hoped all would unite. The Papacy, incensed by this trifling with orthodoxy, and by the assumption of an Imperial right to interfere in matters of faith, denounced the compromise. A schism was the consequence, which lasted until the reign of the Emperor Justin (518-527), when the crafty statesman who guided Justin's policy, his nephew, the famous Justinian, effected a reconciliation. For Justinian already cherished an ambition to win back Italy for the Empire; and he knew that that could not be done without the support of the Papacy. In 519 a papal embassy bearing the olive branch was warmly welcomed at Constantinople; both Emperor and nephew condemned the compromise and accepted the orthodox Catholic faith. Thus the breach was healed.
