You Are a Delegate at the Council of Nicea

What are the mainissues facing you? Christianity has been well established for several centuies, yet there is substantial disagreement over issues such as:
-the nature of sin
-is salvation earned or given?
-Christ’s nature
-what should religious services/mass consist of?
Since this was a major church council, no doubt the delegates engaged in quite a bit of argument. My question: how much would you have known about Christ, apart from what was written in the four gospel accounts?
