The Creeds of Christendom

The Creeds of Christendom, with a History and Critical Notes is a three volume set written by Philip Schaff. The book classifiers and explains many different statements of belief and articles of faith throughout the Christian history. Schaff deals with the history of the creeds, starting with the Ecumenical creeds, and moving to Greek and Roman creeds, then Old Catholic Union creeds, and finally to the Evangelical creeds and Modern Protestant creeds.

Philip Schaff (1819-1893) was a Swiss-born, German-educated Protestant theologian and ecclesiastical historian who spent most of his adult life living and teaching in the United States. Schaff's broad views strongly influenced the German Reformed Church, through his teaching at Mercersburg, Pennsylvania, through his championship of English in German Reformed churches and schools in America, by his edition of the Heidelberg Catechism, and much more. His History of the Christian Church opened a new period in American study of ecclesiastical history.
