Calvinist / Reformed
The Reformed tradition is a branch of Protestant Christianity originating in the Swiss Reformation under Ulrich Zwingli and developed systematically by John Calvin in Geneva. It is defined by its confessional standards — principally the Heidelberg Catechism (1563), the Belgic Confession (1561), the Canons of Dort (1619), and the Second Helvetic Confession (1566) — as well as the Westminster Standards (1647) in the Presbyterian tradition. Reformed theology is characterized by the absolute sovereignty of God in all things, a robust doctrine of double predestination, covenant theology as the organizing framework of Scripture, the spiritual (not bodily) presence of Christ in the Lord's Supper, the regulative principle of worship, and the TULIP doctrines of grace. Reformed churches are found worldwide, from the Dutch Reformed tradition in the Netherlands and North America to Reformed churches in Korea, Hungary, and sub-Saharan Africa.
