On the one hand Christianity, in its later and more developed form, had insensibly cast off the rigid formalism and exclusiveness of Mosaism, and, on the other, had stamped with the brand of heresy the Greek infusion of philosophy and liberalism. Unfortunately, unable clearly to distinguish between the true and the false--between the accidental and fanciful and the permanent and real--timidly cautious of approving anything which seemed connected with heresy--the leaders of the dominant body were prone to seek refuge in a middle course, in regard to the question of flesh-eating, scarcely consistent with strict logic or strict reason. While advocating abstinence as the highest spiritual exercise or aspiration, they seem to have been unduly anxious to disclaim any motives other than _ascetic_--to disclaim, in fine, humanitarian or “secular” reason, such as that of the Pythagoreans. Such was the feeling, apparently, of the later orthodox church, at least in the West. While, however, we thus find, occasionally, a certain constraint and even contradiction in the _theory_ of the first great teachers of the Church, the _practice_ was much more consistent. That, in fact, during the first three or four centuries the most esteemed of the Christian heroes and saints were not only non-flesh-eaters but Vegetarians of the extremest kind (far surpassing, if we give any credit to the accounts we have of them, the _most frugal_ of modern abstainers) is well known to everyone at all acquainted with ecclesiastical and, especially, eremitical history--and it is unnecessary to further insist upon a notorious fact.[64] Titus Flavius Clemens, the founder of the famous Alexandrian school of Christian theology, and at once the most learned and most philosophic of all the Christian Fathers, is generally supposed to have been a native of Athens. His Latin name suggests some connexion with the family of Clemens, cousin of the emperor Domitian, who is said to have been put to death for the crime of _atheism_, as the new religion was commonly termed by the orthodox pagans. He travelled and studied the various philosophies in the East and West. On accepting the Christian faith he sought information in the schools of its most reputed teachers, of whom the name of Pantænus is the only one known to us. At the death of Pantænus, in 190, Clement succeeded to the chair of theology in Alexandria, and at the same time, perhaps, he became a presbyter. He continued to lecture with great reputation till the year 202, when the persecution under Severus forced him to retire from the Egyptian capital. He then took refuge in Palestine, and appears not to have returned to Alexandria. The time and manner of his death are alike unknown. He is supposed to have died in the year 220. Amongst his pupils by far the most famous, hardly second to himself in learning and ability, was Origen, his successor in the Alexandrian professorship.
