We remember that the Christmas festival of to-day is a gradual evolution from times that long antedated the Christian period. We remember that though it celebrates the mightiest event in the history of Christendom, it was overlaid upon heathen festivals, and many of its observances are only adaptations of pagan to Christian ceremonial. [Illustration: Christmas presents. Painting by F. Defregger.] This was no mere accident. It was a necessary measure at a time when the new religion was forcing itself upon a deeply superstitious people. In order to reconcile fresh converts to the new faith, and to make the breaking of old ties as painless as possible, these relics of paganism were retained under modified forms, in the same way that antique columns, transferred from pagan temples, became parts of the new churches built by Christians in honor of their God and his saints. Thus we find that when Pope Gregory sent Saint Augustine as a missionary to convert Anglo-Saxon England he directed that so far as possible the saint should accommodate the new and strange Christian rites to the heathen ones with which the natives had been familiar from their birth. For example, he advised Saint Augustine to allow his converts on certain festivals to eat and kill a great number of oxen to the glory of God the Father, as formerly they had done this in honor of the devil. All pagan gods, it should be explained, were looked upon as devils by the early Christians. On the very Christmas after his arrival in England Saint Augustine baptized many thousands of converts and permitted their usual December celebration under the new name and with the new meaning. He forbade only the mingling together of Christians and pagans in the dances. From these early pagan-Christian ceremonies are derived many of the English holiday customs that have survived to our day. Now get clearly into your head one very important fact. Although at the time when Augustine visited England the date of Christmas had been fixed upon as December 25 there is no biblical reason why this should be so. The gospels say nothing about the season of the year when Christ was born. On the other hand they do tell us that shepherds were then guarding their flocks in the open air. Hence many of the early fathers of the Church considered it most likely that the Nativity took place either in the late summer or the early fall. The point was of no great moment to them, as the early Church made more fuss over the death day of a great or holy person than over his birthday. The birthday is only the day when man is born into mortality, the death day chronicles his birth into immortality. The important fact then which I have asked you to get clearly into your head is that the fixing of the date as December 25th was a compromise with paganism.
