Authority in Religion

Authority in religion addresses the question of what ultimate norm governs Christian belief and practice — what or who has the right to determine what Christians must believe and how they must live. The major positions correspond to the great divisions of Christendom. Roman Catholicism holds to a dual-source authority: Scripture and Sacred Tradition as interpreted by the Magisterium (the teaching authority of the church, centered in the papacy, with infallibility defined by Vatican I, 1870, and Vatican II, 1962–65). Eastern Orthodoxy grounds authority in Scripture, tradition, and the consensus of the seven ecumenical councils, without a single papal head. Protestantism's Reformation principle is sola scriptura (Scripture alone as the supreme norm of faith and practice), though tradition (creeds, confessions, church councils) serves as a subordinate authority. Scripture's own claim to authority is grounded in divine inspiration: "All Scripture is God-breathed" (2 Tim. 3:16–17; cf. 2 Pet. 1:20–21). Jesus consistently appealed to Scripture as final authority (Matt. 5:17–18; John 10:35: "Scripture cannot be broken"). The challenge of sola scriptura is the interpretive question — who interprets Scripture? — which Protestant ecclesiology addresses through the hermeneutical community of the church under the Spirit's guidance, creeds, and confessions as secondary authorities.
