Among Methodists the Wesleyan Quadrilateral, provides a useful tool for understanding the Christian faith. Derived from John Wesley's theological approach, the Quadrilateral refers to Scripture, Tradition, Reason, and Experience. For Wesley scripture was the primary source, but the Christian tradition, reason, and experience added depth of discernment.

In our exploration of the theology of peace and war we take up the Quadrilateral and consider (1) the biblical perspective and how it is illuminated by (2) tradition found in Christian history, (3) reason expressed through different theological perspectives, and (4) practical experience in dealing with conflict.
