Origin of Christmas

The precise origin of assigning December 25 as the birth date of Jesus is unclear. The New Testament provides no clues in this regard. December 25 was first identified as the date of Jesus’ birth by Sextus Julius Africanus in 221 and later became the universally accepted date. One widespread explanation of the origin of this date is that December 25 was the Christianizing of the dies solis invicti nati (“day of the birth of the unconquered sun”), a popular holiday in the Roman Empire that celebrated the winter solstice as a symbol of the resurgence of the sun, the casting away of winter and the heralding of the rebirth of spring and summer. Indeed, after December 25 had become widely accepted as the date of Jesus’ birth, Christian writers frequently made the connection between the rebirth of the sun and the birth of the Son. One of the difficulties with this view is that it suggests a nonchalant willingness on the part of the Christian church to appropriate a pagan festival when the early church was so intent on distinguishing itself categorically from pagan beliefs and practices.

A second view suggests that December 25 became the date of Jesus’ birth by a priori reasoning that identified the spring equinox as the date of the creation of the world and the fourth day of creation, when the light was created, as the day of Jesus’ conception (i.e., March 25). December 25, nine months later, then became the date of Jesus’ birth. For a long time the celebration of Jesus’ birth was observed in conjunction with his baptism, celebrated January 6.

Christmas began to be widely celebrated with a specific liturgy in the 9th century but did not attain the liturgical importance of either Good Friday or Easter, the other two major Christian holidays. Roman Catholic churches celebrate the first Christmas mass at midnight, and Protestant churches have increasingly held Christmas candlelight services late on the evening of December 24. A special service of “lessons and carols” intertwines Christmas carols with Scripture readings narrating salvation history from the Fall in the Garden of Eden to the coming of Christ. The service, inaugurated by E.W. Benson and adopted at the University of Cambridge, has become widely popular.       Brittanica
