form of Astarte.(917) Now Mithra was regularly identified by his worshippers with the Sun, the Unconquered Sun, as they called him;(918) hence his nativity also fell on the twenty-fifth of December.(919) The Gospels say nothing as to the day of Christ’s birth, and accordingly the early Church did not celebrate it. In time, however, the Christians of Egypt came to regard the sixth of January as the date of the Nativity, and the custom of commemorating the birth of the Saviour on that day gradually spread until by the fourth century it was universally established in the East. But at the end of the third or the beginning of the fourth century the Western Church, which had never recognized the sixth of January as the day of the Nativity, adopted the twenty-fifth of December as the true date, and in time its decision was accepted also by the Eastern Church. At Antioch the change was not introduced till about the year 375 A.D.(920) (M220) What considerations led the ecclesiastical authorities to institute the festival of Christmas? The motives for the innovation are stated with great frankness by a Syrian writer, himself a Christian. “The reason,” he tells us, “why the fathers transferred the celebration of the sixth of January to the twenty-fifth of December was this. It was a custom of the heathen to celebrate on the same twenty-fifth of December the birthday of the Sun, at which they kindled lights in token of festivity. In these solemnities and festivities the Christians also took part. Accordingly when the doctors of the Church perceived that the Christians had a leaning to this festival, they took counsel and resolved that the true Nativity should be solemnized on that day and the festival of the Epiphany on the sixth of January. Accordingly, along with this custom, the practice has prevailed of kindling fires till the sixth.”(921) The heathen origin of Christmas is plainly hinted at, if not tacitly admitted, by Augustine when he exhorts his Christian brethren not to celebrate that solemn day like the heathen on account of the sun, but on account of him who made the sun.(922) In like manner Leo the Great rebuked the pestilent belief that Christmas was solemnized because of the birth of the new sun, as it was called, and not because of the nativity of Christ.(923)
