In early Christianity, there was much diversity in beliefs and practices. This separation in Christianity had to deal with the different cultures and their own specific society. For example, the church of Jerusalem took on a very Hebrew character, focusing on the transition from the Mosaic covenant to the Christian covenant and emphasizing ritualistic religious practice, whereas the Roman church focused more on forgiveness and salvation. Eventually integrating Greco-roman style of philosophy with Christian thought in theology. (The Christian Theology Traditions p.89) While being separated in peripheral qualities, the entire Christian church attempted to remain united in one faith. After Arius raised questions concerning essential doctrines of the Christian faith, the leaders of the church, with the help of Constantine, the political leader of the Roman Empire, called the council of Nicaea, which outlined a basic creed, the essential elements of the Christian faith, and also codified the canon of scripture.
(The Christian Theology Traditions p.125) The calling of the council itself was important to unification of Christianity because all of the religious leaders came together to discuss matters of faith. The creed and the canon of scripture offered a standard for the unification of faith regardless of geographic location.
The early Christian church was a conglomeration of various cultures, ideas and ways of thinking, which were bound together through one unifying faith. "The church is the community of believers bound together in one faith and love of Christ."Ã¯Â¿Â½ (Vatican 1)
