The public declaration of what one believes. Biblical confession at its simplest is the cry that Jesus is Lord (Rom 10:9-10): That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. The early church developed brief baptismal confessions that became the Apostles' Creed; conciliar definitions produced the Nicene and Athanasian Creeds; the Reformation produced longer doctrinal confessions: the Augsburg Confession (Lutheran, 1530), the Belgic Confession (Reformed, 1561), the Heidelberg Catechism (Reformed, 1563), the Thirty-Nine Articles (Anglican, 1571), the Westminster Confession (Presbyterian, 1646), the Savoy Declaration (Congregational, 1658), the Second London Baptist Confession (1689). These confessions are not co-equal with Scripture but are faithful summaries of Scripture, providing the church's cumulative confession of biblical doctrine against heresy.
