In this narrativeThe claim that he was a Mithraic priest
In this narrative, Constantine was a devoted follower of Mithraism1.He was, further, a priest of Mithraism himself1.A former Roman soldier, he first encountered the Mithraic faith that spread widely through the army1.Even after legalizing Christianity in 313, he did not erase the traces of sun worship1.This picture draws him as a man straddling two faiths.
In this narrativeThe hand that set Sunday and December 25
Constantine issued a decree to observe "the day of the sun god" (Sunday) in place of the Sabbath (Saturday)1.From then on, Rome's administration, military, and culture settled into resting on Sunday1.December 25, once a Mithraic festival day, also shifted to become the birth date of Christ1.These two decisions built the skeleton of today's Christian calendar.
In this narrativeWhere the word "heresy" began
Emperor Theodosius, who succeeded Constantine, made Christianity Rome's state religion1.He suppressed and executed clergy of other religions1.From this point, anyone who taught something different from the clergy the emperor recognized was called a "heretic"1.The emperor's administrative and military power was mobilized for that suppression1.Even the name Mithramas was, around this time, simply changed to Christmas1.
