Of old, throughout all countries, religion possessed certain things in common, which belonged to the rites and creeds of all nations, and were evidently derived from the primitive traditions of mankind, and, consequently, from a true and Divine revelation. Such were the belief in a golden age, in the fall from a happy beginning, in the penalty imposed on sin, which gave a reason for great mundane calamities--the Deluge chiefly-- the memory of which lived in the traditions of almost every nation; in the necessity of prayer and expiatory sacrifice; in the transmission of guilt from father to son, expressed in all primitive legislations, and to this day preserved in the Chinese laws and customs; in the existence of good and bad spirits, whence, most probably, arose polytheism; in the hope of the future regeneration of man, represented in Greece by the beautiful myth of Pandora's box; and, finally, in the doctrine of eternal rewards and punishments. Each one of these strictly true dogmas underwent more or less of alteration in its passage through the various nations of antiquity, but was, nevertheless, everywhere preserved in some shape or form. At what precise epoch did mankind begin wrongfully to interpret these primitive traditions? When did the worship of idols arise and become universal? No one can tell precisely. All we know for certain is, that a thousand years before Christ idolatry prevailed everywhere, and that even the Jewish people often fell into this sin, and were only brought back by means of punishment to the worship of the true God. But if error tainted the whole system of worship among nations, it differed in the various races of men according to the variety of their character. Ferocity or mildness of manners, acuteness or obtuseness of understanding, activity or indolence of disposition, a burning, a cold, or a temperate climate, a smiling or dreary country, but chiefly the thousand differences of temper which are as marked among mankind as the almost in- finite variety of forms visible in creation, gave to each individual religion its proper and characteristic types, which in after-times, when truth was brought down from heaven for all, imparted to the universal Christian spirit a peculiar outward form in each people, an interior adaptation to its peculiar dispositions, destined in the Divine plan to introduce into the future Catholic Church the beautiful variety requisite to make its very universality possible among mankind.
