BBC article on Christmas being a pagan holiday:
The Gospels do not mention the date of Jesus' birth. It was not until the 4th century AD that Pope Julius I set 25th December as the date for Christmas. This was an attempt to Christianise the Pagan celebrations that already took place at this time of year. By 529, 25th December had become a civil holiday and by 567 the twelve days from 25th December to the Epiphany were public holidays.
Christmas is not only a Christian festival. The celebration has roots in the Jewish holiday of Hanukkah, the festivals of the ancient Greeks, the beliefs of the Druids and the folk customs of Europe.
Midwinter celebrations
Christmas comes just after the middle of winter. The sun is strengthening and the days are beginning to grow longer. For people throughout history this has been a time of feasting and celebration.
Ancient people were hunters and spent most of their time outdoors. The seasons and weather played a very important part in their lives and because of this they had a great reverence for, and even worshipped, the sun. The Norsemen of Northern Europe saw the sun as a wheel that changed the seasons. It was from the word for this wheel, houl, that the word yule (another name for Christmas) is thought to have come. At Winter Solstice the Norsemen lit bonfires, told stories and drank sweet ale.
The Romans also held a festival to mark the Winter Solstice. Saturnalia (from the God Saturn) ran for seven days from 17th December. It was a time when the ordinary rules were turned upside down. Men dressed as women and masters dressed as servants. The festival also involved processions, decorating houses with greenery, lighting candles and giving presents.
Holly is one of the symbols most associated with Christmas. Its religious significance pre-dates Christianity. It was previously associated with the Sun God and was important in Pagan customs. Some ancient religions used holly for protection. They decorated doors and windows with it in the belief it would ward off evil spirits.
Before Christianity came to the British Isles the Winter Solstice was held on the shortest day of the year (21st December). The Druids (Celtic priests) would cut the mistletoe that grew on the oak tree and give it as a blessing. Oaks were seen as sacred and the winter fruit of the mistletoe was a symbol of life in the dark winter months.
Judaism was the main religion of Israel at the time of Jesus' birth. The Jewish midwinter festival of Hanukkah marks an important part of Jewish history. It is eight days long and on each day a candle is lit. It is a time of remembrance, celebration of light, a time to give gifts and have fun.
