Reformed thought is a theological framework that emerged from the Protestant Reformation in the 16th century, primarily associated with figures like John Calvin and Martin Luther. It emphasizes the sovereignty of God, the authority of Scripture, and the necessity of grace through faith for salvation. Central to Reformed thought is the concept of covenant theology, which views God's relationship with humanity as a series of covenants. This perspective shapes the understanding of the church, sacraments, and the role of believers in society, promoting a holistic approach to faith and life.
