The religious people need to know that Christmas is a pagan holiday and has nothing to do with jesus. Santa Claus is a pagan legend. The choice of 25 December for the celebration of the birth of Jesus is that the purpose was to Christianize the pagan festival in Rome of the Dies Natalis Solis Invicti means "the birthday of the Unconquered Sun", a festival inaugurated by the Roman emperor Aurelian (270–275) to celebrate the sun god
Prior to Christianization, the Germanic peoples (including the English) celebrated a midwinter event called Yule (Old English geola or guili).[14] With the Christianization of Germanic Europe, numerous traditions were absorbed from Yuletide celebrations into modern Christmas.[15] During this period, supernatural and ghostly occurrences were said to increase in frequency, such as the Wild Hunt, a ghostly procession through the sky. The leader of the wild hunt is frequently attested as the god Odin and he bears the Old Norse names Jólnir, meaning "yule figure" and the name Langbarðr, meaning "long-beard" (see list of names of Odin).[16]
The god Odin's role during the Yuletide period has been theorized as having influenced concepts of St. Nicholas in a variety of facets, including his long white beard and his gray horse for nightly rides (see Odin's horse Sleipnir), which was traded for reindeer in North America.[17] Margaret Baker comments that "The appearance of Santa Claus or Father Christmas, whose day is 25th of December, owes much to Odin, the old blue-hooded, cloaked, white-bearded Giftbringer of the north, who rode the midwinter sky on his eight-footed steedSleipnir, visiting his people with gifts. … Odin, transformed into Father Christmas, then Santa Claus, prospered with St Nicholas and the Christchild became a leading player on the Christmas stage."[18]
