When messengers went through the various countries bearing tidings of a new religion and of the birth of a Son who brought light and new life into the whole world, they endeavored to retain as many of the established customs as possible, but gave to the old-time festivals a finer character and significance.
As the fact of Christ's birth was not recorded and there was no certainty as to its date, the early Christian Fathers very wisely ascribed it to Yule-tide, changing the occasion from the birthday of the sun to that of the Son. For a while the birth of Christ was celebrated on dates varying from the first to the sixth of January; on the dates of certain religious festivals such as the Jewish Passover or the Feast of Tabernacles; but the twenty-fifth of December, the birthday of the sun, was ever the favorite date.
Pope Julius, who reigned from 337 to 352 A. D., after a careful investigation, considered it settled beyond doubt that Christ was born on or about the twenty-fifth of December, and by the end of the fifth century that date was very generally accepted by Christians. The transition from the old to the new significance of Yule-tide was brought about so quietly and naturally that it made no great impression on the mind of the masses, so nothing authentic can be learned of the early observance of Christmas.
The holly, laurel, mistletoe, and other greens used by the Druids still served as decorations of the season, not as a shelter for fairies, as in former days, but as emblems of resurrection and of immortal hope.
The glorious luminary of day, whether known as Balder, Baal, Sol, or any other of the innumerable names by which it was called by the primitive peoples, still gladdens the hearts of mortals at Yule-tide by "turning-back" as of old; only to-day it yields its place to a Superior Power, in whose honor Yule-tide is observed.
All Christendom owes a debt of gratitude to its pagan forbears for the pleasant features of many of its holidays and especially for those of Yule-tide. The Fathers of the early church showed rare wisdom in retaining the customs of these ante-Christian festivals, imbuing them with the spirit of the new faith and making them emblematic of a purer love and hope.
New Year's Day as a feast day is one of the oldest, if not the oldest, on record. It is mentioned by Tacitus in the First Century, but first referred to as a Christian festival about the year 567.
In Rome the day was dedicated by Numa to the honor of god Janus, for whom Julius Cæsar named the month of January. Numa ordained that it should be observed as a day of good-humor and good-fellowship. All grudges and hard feelings were to be forgotten. Sacrifices of cake, wine, and incense were to be made to the two-faced god who looked forward and backward. Men of letters, mechanics, and others were expected to give to the god the best they had to offer of their respective arts. It was the great occasion of the entire year, as it is now in many countries.
The date of New Year's Day has varied among different nations. Among the Egyptians, Chinese, Jews, and Romans it has been observed on dates varying from March first to December twenty-fifth. It was as late as the Sixteenth Century before the date of January first was universally accepted as the New Year by the Romans. Nations retaining the Gregorian calendar, such as Russia and Greece, observe it thirteen days later than those who reckon time by the Julian calendar.
