Many Christian theologians [153] have supposed that the debased condition—moral and spiritual—of the Eastern Church of that period must have alienated the hearts of many and driven them to seek a healthier spiritual atmosphere in the faith of Islam which had come to them in all the vigour of new-born zeal. [154] For example, Dean Milman [155] asks, “What was the state of the Christian world in the provinces exposed to the first invasion of Mohammedanism? Sect opposed to sect, clergy wrangling with clergy upon the most abstruse and metaphysical points of doctrine. The orthodox, the Nestorians, the Eutychians, the Jacobites were persecuting each other with unexhausted animosity; and it is not judging too severely the evils of religious controversy to suppose that many would rejoice in the degradation of their adversaries under the yoke of the unbeliever, rather than make common cause with them in defence of the common Christianity. In how many must this incessant disputation have shaken the foundations of their faith! It had been wonderful if thousands had not, in their weariness and perplexity, sought refuge from these interminable and implacable controversies in the simple, intelligible truth of the Divine Unity, though purchased by the acknowledgment of the prophetic mission of Mohammed.” Similarly, Caetani sees in the spread of Islam, among the Christians of the Eastern Churches, a revulsion of feeling from the dogmatic subtleties introduced into Christian theology by the Hellenistic spirit. “For the East, with its love of clear and simple concepts, Hellenic culture was, from the religious point of view, a misfortune, because it changed the sublime and simple teachings of Christ into a creed bristling with incomprehensible dogmas, full of doubts and uncertainties; these ended with producing a feeling of deep dismay and shook the very foundations of religious belief; so that when at last there appeared, coming out suddenly from the desert, the news of the new revelation, this bastard oriental Christianity, torn asunder by internal discords, wavering in its fundamental dogmas, dismayed by such incertitudes, could no longer resist the temptations of a new faith, which swept away at one single stroke all miserable doubts, and offered, along with simple, clear and undisputed doctrines, great material advantages also. The East then abandoned Christ and threw itself into the arms of the Prophet of Arabia.” [156]
