The Institutes of the Christian Religion

"The Institutes of the Christian Religion," written by John Calvin in the 16th century, is a foundational text of Protestant theology. It lays out Calvin's views on God, human nature, and salvation, emphasizing God's sovereignty and grace. The work is structured into four main books covering topics such as the nature of God, the role of Christ, the Holy Spirit, and the church. Calvin's ideas significantly influenced Reformed churches and shaped Protestant thought, advocating for a faith rooted in scripture and personal understanding of God, which contrasted with Catholic practices of the time.
