I could use some help here with the origins of Christians celebrating Christmas. I began teaching a community-wide Bible study in September and we have about 10 or so people coming and it is wonderful beyond words what God is doing - that's another story. Anyway, my plans are to teach everything about the Christmas story beginning this Thursday (three nights in November and three night in December). I want to cover everything: Jesus is God's Son and Jesus is God. Why he had to come to earth in the first place and why he alone, was the only choice. All the Old Testament prophecies concerning his birth and how they came true. The 400 years between the Old and New Testament and what was going on leading up to the birth of Christ. The announcement to Zechariah and Elizabeth and the birth of John the Baptist and his purpose. The two lineages of Christ in Matthew and Luke. I want to go into explicit detail about Herod, the Wise Men, the shepherds, the angel, Mary, Joseph, Anna and Simeon and present them and their stories realistically. OK, I've got all of that down. But I need some help in finding accurate information about the church's first acknowledgement and celebration of Christmas. Why the 25th of December? Why the traditions attached? I've got the basics of all that, BUT everywhere I look give slightly conflicting information and I do not want to teach anything incorrectly. Does anybody know of any resources that to the best of your knowledge is 100% accurate about the origins of the Church and Christmas as a religious holiday?
