Ecclesiology: The Doctrine of the Church
Ecclesiology, the theological study of the church, examines the nature, purpose, and mission of the Christian community. This foundational doctrine explores how Christ's body functions in the world, its essential characteristics, and its role in God's redemptive plan.
At its core, ecclesiology understands the church as both a divine and human reality—the mystical body of Christ and a historical institution. It encompasses the church's origin, attributes, organization, practices, and mission in the world.
