The Reformed Church is a branch of Protestant Christianity that emerged during the 16th century Reformation. It emphasizes the sovereignty of God, the authority of Scripture, and the necessity of grace through faith. The movement is rooted in the teachings of reformers like John Calvin and Huldrych Zwingli, who sought to reform the practices and beliefs of the Roman Catholic Church. Reformed Churches are known for their distinct theological principles, including the Five Points of Calvinism, which outline beliefs about salvation. They often practice infant baptism and celebrate the Lord's Supper, viewing these sacraments as means of grace. The Reformed tradition has influenced various denominations worldwide, including the Presbyterian Church.
