John Calvin's Institutes of the Christian Religion is a defining book of the Reformation and a pillar of Protestant theology. First published in Latin in 1536 and in Calvin's native French in 1541, the Institutes argues for the majesty of God and for justification by faith alone. Here, Bruce Gordon provides an essential biography of Calvin's influential and enduring theological masterpiece, tracing the diverse ways it has been read and interpreted from Calvin's time to today.
