Institute of the Christian Religion

*The Institutes of the Christian Religion*, written by John Calvin, is a foundational theological work that systematically explains Christian beliefs and doctrine. First published in 1536, it aims to clarify the principles of the Protestant Reformation, emphasizing God's sovereignty, human sinfulness, and salvation through faith. The book serves as a guide for understanding Christian faith, church practices, and moral living, shaping Reformed theology. Its clear, structured approach has had a lasting influence on Protestant thought, especially within Calvinism, and remains a significant theological reference for Christians worldwide.
