Well, for one thing, during the first two centuries of Christianity there was strong opposition to recognizing birthdays of martyrs or, for that matter, of Jesus,” states the Encyclopedia Britannica. Why? Christians viewed birthday celebrations as a pagan custom, something to be avoided altogether. In fact, no mention of the date of Jesus’ birth can be found in the Bible.
Further, in the fourth century C.E., despite the stand taken by the early Christians against the custom of celebrating birthdays, the Catholic Church instituted Christmas. The church wanted to strengthen its position by removing one of the main obstacles in its way—the popularity of the pagan Roman religions and their winter solstice festivals. Each year, from December 17 through January 1, “most Romans feasted, gamed, reveled, paraded, and joined in other festivities as they paid homage to their deities,” says Christmas in America, by Penne L. Restad. And on December 25, the Romans celebrated the birth of the Invincible Sun. Instituting Christmas on that day, the church cajoled many Romans into celebrating the birth of Jesus instead of the birth of the sun. Romans “were still able to enjoy the trappings of these midwinter festivals,” says Santa Claus, a Biography, by Gerry Bowler. In reality, they “continued to mark the new days with old ways.”
