and you know that if Constantine had lost that military battle, he would not have been emperor and would not have been in a position to legalize Christianity.
And then the church would have been in a weaker position in its fight against arianism. Much weaker.
It was 312 AD that Constantine won the military battle.
It was 318 AD that Arius began his heretical movement.
One of my points is that all of that was happening at the same time.
The Church would not have been in a position to convene a council if she remained underground. But military battles of Constantine had nothing to do with the Nicaean Council’s decisions. In fact, Arianism was the prevalent teaching in the church after Christianity was legalized, so you can just as easily claim that Constantine’s military victories spurred Arianism.
