A group of Swiss, Dutch, and some German churches, which were the direct outcome of the Protestant Reformation. There are three bodies in the United States. They are generally Calvinistic in doctrine. Their Heidelberg Catechism emphasizes the general comfort of redemption in Christ, while besides this the Westminster Catechism emphasizes the sovereignty of God. In government they differ from Presbyterian churches only in the names of church offices and some minor details. There is a web site with a list of Reformed Church groups.
