They are not here to say what they preferred. Suffer death as a martyr or cede to a similar but apostate religion. Honestly, I do not see how some here look at this person as some kind of savior of religion. He forced his beliefs on his subjects and some people here praise him. This is not what Jesus preached. To praise fascism because you believe in some of its tenets is still wrong. It is still a sin.
I am not celebrating Constantine. What he really was or wasn’t I can’t say. I know from Eusebius (Christian historian) terrible suffering was occurring up to this point and then persecution was ended. BTW, Eusebius was an Arian not a Trinitarian. Problem was not Constantine per se, but as Christianity became stronger and influential it brings in wolves with false motives. Happens in any point in time.
