In 1523, the Swiss reformer Huldrych Zwingli set down sixty-seven short theses that would reshape the church in Zurich and far beyond. Written for public debate, they are startling in their clarity: Christ alone is the way to salvation, Scripture is the church's true authority, and worship must be stripped of everything that obscures the Gospel. This modern-English edition renders Zwingli's classic in clear, inviting prose while remaining faithful to the meaning and spirit of the original. Each chapter follows the structure of the Sixty-Seven Articles, with introductions that place the theses in their historical context. Whether you are a student of church history, a seeker after spiritual classics, or simply curious about the voices that shaped the modern world, this edition offers a direct encounter with one of the Reformation's founding texts.
