Church Authority

Lutheran ecclesiology defines the church (in its essential, invisible form) as the assembly of all believers among whom the Gospel is rightly preached and the sacraments are rightly administered, according to the Gospel. This definition, from the Augsburg Confession Article VII, deliberately grounds ecclesial identity in theological content rather than institutional hierarchy. The visible church includes both true believers and hypocrites; only God knows the true church.

Lutheran churches reject the jurisdictional authority of the papacy, which the Smalcald Articles and Treatise on the Power and Primacy of the Pope (1537) repudiate at length. Bishops or superintendents are accepted as legitimate offices of oversight, but their authority is functional and ministerial rather than ontological. Church polity varies significantly across global Lutheranism: European state churches often retain episcopal structures in apostolic succession, while American Lutheran bodies use more synodical or congregational governance. The ultimate authority in the church is Scripture, interpreted through the confessional documents of the Book of Concord.
