In Christian theology, ecclesiology is the study of doctrine about the Church itself as a community and about the churches own view of its mission and role.
That neans that ecclesiology looks at the role of the church in salvation, at its origin, its relationship to the historical Christ, its discipline, its destiny (see Eschatology) and its leadership.
In addition to describing a broad discipline of theology, ecclesiology may be used in the specific sense of a particular church or denomination’s character, self-described or otherwise. This is the sense of the word in such phrases as Roman Catholic ecclesiology, Lutheran ecclesiology, and ecumenical ecclesiology.
Questions asked by ecclesiology
Ecclesiology asks the questions:
- Who is the Church? Is it a visible or earthly corporation -- a "church" in the sense of a specific denomination or institution, for instance? Or is it the body of all believing Christians regardless of their denominational differences and disunity? What is the relationship between living Christians and departed Christians (the "cloud of witnesses" Epistle to the Hebrews 12:1)-- do they (those on Earth and those in Heaven) constitute together the Church?
- Must one join a church? That is, what is the role of corporate worship in the spiritual lives of believers? Is it in fact necessary? Can salvation be found outside of formal membership in a given faith community, and what constitutes "membership?" (Baptism? Formal acceptance of a creed? Regular participation?)
- What is the authority of the Christian church? Who gets to interpret the doctrines of the Church? Is the organizational structure itself, either in a single corporate body, or generally within the range of formal church structures, an independent vehicle of revelation or of God's grace?
- What does the Church do? What are the sacraments, divine ordinances, and liturgies, in the context of the Church, and are they part of the Church's mission to preach the Gospel?
- How should the Church be governed? What was the mission and authority of the Apostles, and is this handed down through the sacraments today? What are the proper methods of choosing clergy such as bishops and priests, and what is their role within the context of the Church?
- What is the ultimate destiny of the Church in Christian eschatology?
