In this course, students will explore the historical debates and the doctrinal formulations of the seven ecumenical councils (325-787 AD). This course will address the development of fundamental themes in trinity, Christology, ecclesiology, sacramental theology, and the theology of iconography. Students will be introduced to the historical context of these debates and attend to the relationship between the early church and its relationship to secular authority. The course will further examine the theological method of early and late antique Christian thinkers that gave rise to these doctrines as well explore the enduring contribution of these conciliar debates for ecumenical dialogue and contemporary theology.
