The Reformed Tradition is a branch of Protestant Christianity that emerged in the 16th century during the Protestant Reformation. It is rooted in the teachings of theologians like John Calvin and Huldrych Zwingli, emphasizing the sovereignty of God, the authority of Scripture, and the necessity of grace through faith. This tradition is characterized by its focus on covenant theology, which views God's relationship with humanity as a series of covenants. Reformed churches often practice infant baptism and celebrate the Lord's Supper, reflecting their beliefs about God's promises and the communal nature of faith.
