This course will provide an introduction to the theology of the Church and the Church's understanding of itself as a principal mediator of the mystery and grace of God in the world. The approach of the course will be threefold: 1) a study of the historical development of ecclesial structures with special emphasis on understanding the ecclesiology of the second Vatican Council. This will include, a discussion of some pertinent issues arising from the Council such as the magisterium, collegiality, and ministry; 2) an understanding of the diverse theologies of Church through some of the primary images and models in which it understands itself; and 3) an attempt to understand the ecumenical emphasis of Vatican II that has given rise to a renewed interest in interdenominational interreligious dialogue, mission and inculturation, and the emergence of contextual approaches such as the feminist and liberationist methodologies.
