Early Christianity - Ecclesiology

Ecclesiology

Rodney Stark estimates that the number of Christians grew by approximately 40% a decade during the first and second centuries. This phenomenal growth rate forced Christian communities to evolve in order to adapt to their changes in the nature of their communities as well as their relationship with their political and socioeconomic environment. As the number of Christians grew, the Christian communities became larger, more numerous and farther apart geographically. The passage of time also moved some Christians farther from the original teachings of the apostles giving rise to teachings that were considered heterodox and sowing controversy and divisiveness within churches and between churches.

Robert Haight posits the development of ecclesiology in the form of "Early Catholicism" as one response to the problem of church unity. Thus, the solution to division arising from heterodox teaching was the development of "tighter and more standardized structures of ministry. One of these structures is the tri-partite form of church leadership consisting of bishops, elders and deacons that Ignatius of Antioch urged churches to adopt, writing that "You cannot have a church without these." Over the course of the second century, this organizational structure became universal and continues to be used in the Catholic, Orthodox and Anglican churches as well as in some Protestant denominations.

Despite its mention of bishops, there is no clear evidence in the New Testament that supports the concepts of dioceses and monepiscopacy (i.e. the rule that all the churches in a geographic area should be ruled by a single bishop). Scholars point to evidence that Christian communities such as Rome had many bishops and that the concept of monepiscopacy was still emerging when Ignatius was urging his tri-partite structure on other churches.

Robert Williams posits that the "origin and earliest development of episcopacy and monepiscopacy and the ecclesiastical concept of (apostolic) succession were associated with crisis situations in the early church."
