This council was the first of the Ecumenical Councils. This council produced the first official doctrine of the Catholic Church, the Nicene Creed. Also, they debated the proper date to celebrate Easter. They decided that 40 days after Ash Wednesday would be the proper date. Also, the Aryans thought that Jesus was divine, but a step below God. The council then restated that Jesus is in fact on the same level as God and that Jesus and God are the same person.
