Indeed because it wasn't some show orchestrated by Constantine but a Council convened by the church.
Protestant propaganda is laughable when one actually does the reaserch.
I'm sure there's a handful of impressionable 13 year old who'd buy this nonsense at some 'bible study' but the facts are Constantine never made any tate religions, wasn't baptised till his deathbed, and held arian views up till then. He deffered to the church to do what it liked, and the 'great contribution' he made? He made a big speech that folks shouldn't resort to violence over religious differences.
I gather you were there to observe Constantine personally?
. . . given the emphatic nature of your comment . . . Oh, right, knee-jerk SOP.
