While the Reformed tradition originated with Huldrych Zwingli and was more fully developed with John Calvin, it was John Knox who made significant contributions to this movement as it unfolded in Scotland. John Knox: An Introduction to His Life and Works traces the life and thought of John Knox in a succinct and readable way. While a number of biographies tell the story of the famous Scottish reformer, professors Kyle and Johnson take the reader in a different direction, offering an interpretation of his writings. They take a chronological approach to his works—leading the reader through his early years, his exile, and his return to Scotland—allowing them to speak for themselves, an approach that also tells the story of Knox's life and ideas.
