Wesleyan Quadrilateral

The Wesleyan Quadrilateral, or Methodist Quadrilateral, is a methodology for theological reflection that is credited to John Wesley, leader of the Methodist movement in the late 18th Century. The term itself was coined by 20th century American Methodist scholar Albert C. Outler.

This method based its teaching on four sources as the basis of theological and doctrinal development. These four sources are scripture, tradition, reason, and Christian experience.

Upon examination of Wesley's work, Outler theorized that Wesley used four different sources in coming to theological conclusions. Wesley believed, first of all, that the living core of the Christian faith was revealed in "scripture" as the sole foundational source. The centrality of scripture was so important for Wesley that he called himself "a man of one book". However, doctrine had to be in keeping with Christian orthodox "tradition." So, tradition became in his view the second aspect of the so-called Quadrilateral. Furthermore, believing, as he did, that faith is more than merely an acknowledgment of ideas, Wesley as a practical theologian, contended that a part of the theological method would involve "experiential" faith. In other words, truth would be vivified in personal experience of Christians (overall, not individually), if it were really truth. And every doctrine must be able to be defended "rationally." He did not divorce faith from reason. Tradition, experience, and reason, however, are subject always to scripture, which is primary.

Each of the "legs" of the Wesleyan Quadrilateral must be taken in balance, and none of the other three apart from scripture should be viewed as being of equal value or authority with scripture. None of these should be taken in isolation without the balancing effect of the others, and always Scripture should have the central place of authority.

In practice, at least one Christian denomination based on the teaching of Wesley, the United Methodist Church, asserts that "Wesley believed that the living core of the Christian faith was revealed in Scripture, illumined by tradition, vivified in personal experience, and confirmed by reason. Scripture [however] is primary, revealing the Word of God 'so far as it is necessary for our salvation.'"
