Chistmas in Chistian church

BUT HOW DID CHRISTMAS GET INTO THE CHRISTIAN CHURCH?
The day for this worship had been selected in honor of Mithra, the sun god. December 25 was dedicated to the keeping
of his birthday. Therefore sincere Christians considered it to be a form of sun worship. The sun had reached its lowest angle in the sky on December 21 (the winter solstice), and the 25th was the first observable day in which it began rising in the noon sky. So December 25 had, for centuries, been celebrated as the “birth of the sun god.” But, back in those earlier centuries, earnest believers recognized that Christians dare not accept pagan practices or pagan holidays. These heathen customs are not found in the Bible as being used by Christians, so they ought to be shunned by conscientious Christians.
“A feast was established in memory of this event [Christ’s birth] in the fourth century. In the fifth century the Western Church ordered it to be celebrated forever on the day of the old Roman feast of the birth
of Sol [the Latin word for ‘sun’], as no certain knowledge of the day of Christ’s birth existed.”—Encyclopedia Americana (1944 edition), “Christmas.”
