Constantine Imposed an Imposter Jesus
Constantine's Pagan Christianity (You Tube video 11 minutes or 44 minute version) - same Christian ministry professional documentary- says at 8:20 mark that Constantine thought to change the times and days (Sabbath). Also, contends that in Bible hell fire meant destruction, not torment, but pagans thought it was torment. It cites Jesus spoke of fearing God who can "destroy both body and soul in hell." (Matt 10:28.) But this ignores Jesus spoke about their "worm dieth not."
Deception of Constantine - You Tube. Are we worshipping a version of Jesus created by a die-hard pagan? Excellent documentary showing the Arch of Constantine disproves that Constantine at the Battle of Milvan reported the battle was given by Jesus. That was made up more than a decade later.
