What really happened at the council of Nicea?

In class, we talked about the council in Nicea, and how Constantine ruled on matters that were causing controversy in the Christian church and it got me thinking what exactly were those matters that Constantine had to decide on. One thing that they decided on was the trinity, and for those of you who have no idea what that is, which is saying that the God the Father, Jesus Christ the Son and the Holy Spirit are three leader who are equal and they are one Godhead. The most heated issue was the "Who is Christ?" question, people had a hard time understanding who he was and what he was. Constantine made the 300 bishops who attended the council create a doctrine that was later called the Nicene Creed. This creed was adopted by the Church and enforced by the Emperor (Constantine). This creed is similar the Apostle's Creed which is widely used in churches today. It is important to note that the bishops did not invent the doctrine but affirmed the teaching of the Apostles in the Bible. To see some sited passages they used visit this site: http://www.gotquestions.org/council-of-Nicea.html The council came at a time when Constantine's empire was beginning to crumble and he knew that he needed his people to unite and not be fighting against each other but rather uniting against a common enemy.

The Nicene Creed

I believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible.

And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds; God of God, Light of Light, very God of very God; begotten, not made, being of one substance with the Father, by whom all things were made.

Who, for us men and for our salvation, came down from heaven, and was incarnate by the Holy Spirit of the virgin Mary, and was made man; and was crucified also for us under Pontius Pilate; He suffered and was buried; and the third day He rose again, according to the Scriptures; and ascended into heaven, and sits on the right hand of the Father; and He shall come again, with glory, to judge the quick and the dead; whose kingdom shall have no end.

And I believe in the Holy Ghost, the Lord and Giver of Life; who proceeds from the Father and the Son; who with the Father and the Son together is worshipped and glorified; who spoke by the prophets.

And I believe in one holy catholic and apostolic Church. I acknowledge one baptism for the remission of sins; and I look for the resurrection of the dead, and the life of the world to come. Amen.
