Written in 1525, at the height of the Reformation, Huldrych Zwingli's On True and False Religion is one of the founding documents of Protestant theology. In this clear, faithful modern-English edition, the great Zurich reformer's masterpiece is opened up for today's readers. Zwingli walks through the Apostles' Creed, showing what it means to trust in God the Father, in Christ, and in the Holy Spirit, and he sets out his revolutionary understanding of the church, the sacraments, and the Christian life. His famous teaching on the Lord's Supper — that the bread and wine are signs of Christ's presence, not the body itself — changed the course of Western Christianity. Written with warmth, learning, and pastoral urgency, this is a book that speaks across five centuries. Whether you are a student of history, a seeker, or a believer wanting to understand the roots of Reformed faith, this edition invites you into the heart of the Reformation.
