Context of Christianity

Christianity arose in the 1st century in the region of Palestine. It grew out of Judaism, but also came in contact with pagan mystery religions, Greek philosophy, and the cult of the Roman state.
The Council of Nicea

In 325, Constantine called the Council of Nicea in the hopes that Christian leaders could work out their differences over Arianism, a controversial belief about Christ's relation to God.
Jesus of Nazareth

Christianity was founded by Jesus Christ. Christians believe, and most scholars agree, that Jesus was an actual historical figure and a quite intriguing person.
The Apostles

Within 20 years of Jesus' death, his followers had spread the Christian faith as far as Rome. Most of the original 12 disciples of Jesus met violent deaths.

Persecution of the Church

In its first three centuries, the Christian church endured persistent and often severe persecution at the hands of the Roman authorities. This would have significant historical and theological consequences for the developing faith.
The Church Fathers

The time between Christ and Constantine was an especially fertile period of doctrinal development. Some of the most learned minds in Christianity set out to explain the faith to outsiders, develop it for believers, and distinguish "orthodoxy" from "heresy."
