TRIVIA: CHRISTMAS STARTED IN 400CE
Rome adopted Christianity around 300CE. The convergence from the Pagan religions to Christianity included inventing Christian Holidays to coincide with Pagan holidays. Christmas was one of these inventions. At first, both holidays were celebrated as one to avert war and civil unrest. The church had Christmas mass and the Saturnalia was celebrated at home.
With the invention of a God man Jesus came the religious invention of his birth day. Because there is no record of his birth day in the two different stories in Mathew and Luke it was decided that the Pagan day of December 25 would be used to over shadow the Pagan Dec. 25 holiday.
With time the church religion through sheer force, violence, threats and death, pushed out the Pagan holidays all together leaving only the Christian holidays. The term “pagan” was adopted to mean “godless” or “heathen” by the Christians and of course they had to convert or be exterminated.
