Did you know Constantine didn't invent the trinity at the council of Nicaea?
I stumbled upon his letter to Alexander of Alexandria and Arius that has been preserved. Alexander and Arius were fighting concerning the divinity of Jesus. Arius didn't believe in it.
They split up into sects.
In his letter to both of them, Constantine describes their differences โto be of a truly insignificant character, and quite unworthy of such fierce contentionโ (actual quote).
There are at least 10 places in the short letter where he describes their split as โinsignificantโ or as โslight differencesโ. He calls on them to accept their differences because they have the same religion.
That didn't work and so they did the council of Nicaea. It's actually the bishops who decided to exile Arius and his followers. And now, we have sects of Islam and sects of Christianity fighting over truly insignificant differences. ๐๐ป๐๐ป๐๐ป
