Volume 3 of The Annotated Luther series presents five key writings that focus on Martin Luther’s understanding of the gospel as it relates to church, sacraments, and worship. Included in the volume are: The Babylonian Captivity of the Church (1520); The German Mass and Order of the Liturgy (1526); That These Words of Christ, “This is my Body,” etc., Still Stand Firm Against the Fanatics (1527); Concerning Rebaptism (1528), and On the Councils and the Church (1539). Luther refused to tolerate a church built on human works, whether it was the pope’s authority or the faith or decision of individual believers. This is the thread that runs through all the texts in this volume: the church and sacraments belong to Christ, who founded and instituted them. Each volume in The Annotated Luther series contains new introductions, as well as annotations, illustrations, and notes to help shed light on Luther’s context and interpret his writings for today. The translations of Luther’s writings include updates of Luther’s Works American Edition, or entirely new translations of Luther’s German or Latin writings.
