Institutes of the Christian Religion
Institutes of the Christian Religion () is John Calvin's seminal work of systematic theology. Regarded as one of the most influential works of Protestant theology, it was published in Latin in 1536 (at the same time as Henry VIII of England's Dissolution of the Monasteries) and in his native French language in 1541, with the definitive editions appearing in 1559 (Latin) and in 1560 (French).
