We can now see why no definite cause for the monastic institution can be given and no date assigned for its origin. It did not commence at any fixed time and definite place. Various philosophies and religious customs traveled for centuries from country to country, resulting in singular resemblances and differences between different ascetic or monastic sects. Christian monasticism was slowly evolved, and gradually assumed definite organization as a product of a curious medley of Heathen-Jewish-Christian influences. A few words should be said here concerning the influence of the Bible upon monasticism. Naturally the Christian hermits and early fathers appealed to the Bible in support of their teachings and practices. It is not necessary, at this point, to discuss the correctness of their interpretations. The simple fact is that many passages of scripture were considered as commands to attain perfection by extraordinary sacrifices, and certain Biblical characters were reverenced as shining monastic models. In the light of the difficulties of Biblical criticism it is easy to forgive them if they were mistaken, a question to be discussed farther on. They read of those Jewish prophets described in Hebrews: "They went about in sheepskins, in goatskins; ... wandering in deserts and mountains and caves, and the holes of the earth." They pointed to Elijah and his school of prophets; to John the Baptist, with his raiment of camel's hair and a leathern girdle about his loins, whose meat was locusts and wild honey. They recalled the commandment of Jesus to the rich young man to sell all his possessions and give to the poor. They quoted the words, "Take no thought for the morrow what ye shall eat and what ye shall drink or wherewithal ye shall be clothed." They construed following Christ to mean in His own words, "forsaking father, mother, brethren, wife, children, houses and lands." They pointed triumphantly to the Master himself, unmarried and poor, who had not "where to lay his head." They appealed to Paul's doctrine of marriage. They remembered that the Church at Jerusalem was composed of those who sold their possessions and had all things in common. Whatever these and numerous other passages may truly mean, they interpreted them in favor of a monastic mode of life; they understood them to teach isolation, fastings, severities, and other forms of rigorous self-denial. Accepting Scripture in this sense, they trampled upon human affection and gave away their property, that they might please God and save their souls.
