Islam has, moreover, been represented as a reaction against that Byzantine ecclesiasticism, [159] which looked upon the emperor and his court as a copy of the Divine Majesty on high, and the emperor himself as not only the supreme earthly ruler of Christendom, but as High-priest also. [160] Under Justinian this system had been hardened into a despotism that pressed like an iron weight upon clergy and laity alike. In 532 the widespread dissatisfaction in Constantinople with both church and state, burst out into a revolt against the government of Justinian, which was only suppressed after a massacre of 35,000 persons. The Greens, as the party of the malcontents was termed, had made open and violent protest in the circus against the oppression of the emperor, crying out, “Justice has vanished from the world and is no more to be found. But we will become Jews, or rather we will return again to Grecian paganism.” [161] The lapse of a century had removed none of the grounds for the dissatisfaction that here found such violent expression, but the heavy hand of the Byzantine government prevented the renewal of such an outbreak as that of 532 and compelled the malcontents to dissemble, though in 560 some secret heathens were detected in Constantinople and punished. [162] On the borders of the empire, however, at a distance from the capital, such malcontents were safer, and the persecuted heretics, and others dissatisfied with the Byzantine state-church, took refuge in the East, and here the Muslim armies would be welcomed by the spiritual children of those who a hundred years before had desired to exchange the Christian religion for another faith. Further, the general adoption of the Arabic language throughout the empire of the caliphate, especially in the towns and the great centres of population, and the gradual assimilation in manners and customs that in the course of about two centuries caused the numerous conquered races to be largely merged in the national life of the ruling race, had no doubt a counterpart in the religious and intellectual life of many members of the protected religions. The rationalistic movement that so powerfully influenced Muslim theology from the second to the fifth century of the Hijrah may very possibly have influenced Christian thinkers, and turned them from a religion, the prevailing tone of whose theology seems at this time to have been Credo quia impossibile. A Muhammadan writer of the fourth century of the Hijrah has preserved for us a conversation with a Coptic Christian which may safely be taken as characteristic of the general mental attitude of the rest of the Eastern Churches at this period:—
