His gospel, the "Tao Teh King," was written by him. "Tao" means "the way." Christ was called "the Way." Man, according to this gospel, is both a material and a spiritual being. By the renunciation of riches and worldly enjoyments the soul attains to immortality. The most divine of mortals are, like Enoch and Elijah, translated to heaven without suffering death. Laou-tsze taught that men to be righteous must become "as little children." Christ said: "Except ye be converted and become as little children, ye shall not enter into the kingdom of heaven" (Matt. xviii, 3). The more ignorant followers of Laou-tsze, like the more ignorant followers of Christ, believe that many diseases are caused by evil spirits, and their priests, like Christ, practice exorcism to expel them. Like the Catholics, they have monasteries and convents. Of Laou-tsze's writings Prof. Montuci, the Italian philologist, says: "Many things about a triune God are so clearly expressed that no one who has read this book can doubt that the mystery of the Holy Trinity was revealed to the Chinese five centuries before the coming of Christ." There is one element in Christianity which was not borrowed from Paganism--religious intolerance. Referring to Buddhism, Confucianism, and Taouism, a writer on China says: "Between the followers of the three national religions there is not only a total absence of persecution and bitter feeling, but a very great indifference as to which of them a man may belong.... Among the politer classes, when strangers meet, the question is asked: 'To what sublime religion do you belong?' and each one pronounces a eulogium, not on his own religion, but on that professed by the others, and concludes with the oft-repeated formula: 'Religions are many; reason is one; we are all brothers.'" Zoroaster. The Persian prophet Zoroaster lived and wrote at least 1200 years before the Christian era. From his teachings some of the most important doctrines of Christianity, as well as of Judaism, were derived. According to the Persian theology the universe is ruled by two great powers, Ormuzd (God) and Ahrimanes (Satan). The one represents light, the other darkness; the one is good, the other evil. Between these two powers there is perpetual war. The center of battle is man, each striving for his soul. God created man with a free will to choose between good and evil. Those who choose the good are rewarded with everlasting life in heaven; those who choose the evil are punished with endless misery in hell; while those in whom the good and evil are balanced pass into an intermediate state (purgatory), to remain until the last judgment.
