alen, i think you're just gonna have to enlighten us on this
Haha, ok.
Well, the ruler is God's representative on Earth while the church comes from Jesus of Nazareth.
It means.... The Ruler=God (the Father) while the Church= The Son.
If the father and the son are of the same substance (they are equal) then the church and the emperor are equal. But if they aren't of the same substance and if the father is above the son then it means that The Emperor is above the Church.
This is where the Church saw the danger if Arianism was to be accepted. It would mean that the emperor is above the church.
Logically, Arianism is good for the Emperor. If Arianism was accepted by the church then the church would have accepted that the emperor is the main guy.
But the Emperor Constantine the First didn't interfere and he didn't support Arius.
There are many debates why he didn't do it, but he was an extremely smart guy (he wasn't a Christian yet when these things were being decided) and he saw the failure of Diocletian's religious persecutions. He knew that he must work together with the christian church and he supported it.
The future proved him right because the co-operation of the Byzantine state and the Ortodox church is what made Byzantine exsist as a power for +1100 years.
Now, what if Constantine supported Arius on the council of Nicaea ? What if Arianism won back then ?
Were we going to talk about the trinity today ?
I was just trying to show you how the decision of one single man influenced the beliefs of some people today, 1700 years later.
