TWoY: "--advent --preparation, Christians would spend 40 days in penance, prayer, and fasting to prepare for this celebration; originally, there was little connection between Advent and Christmas.
By the 6th century, however, Roman Christians had tied Advent to the coming of Christ. But the “coming” they had in mind was not Christ’s first coming in the manger
That why the advent of Armageddon, Christ coming again, the 4st time has such an emotional hold on believers. We used to have 4 candles lit in succession to mark the nearness of the judgement, by Santa, aka Christ. Candles on a wreath, a circular counting you did not know whether you were coming or going, dates mattered.
