# Confessions and Creeds

During the sixteenth and seventeenth centuries the Reformed churches composed a number of Reformed confessions which distinguished the Reformed faith not only from Roman Catholicism but also from the other branches of the Protestant Reformation churches. Among these confessions are the Confession of Faith or Belgic Confession (1561), the Heidelberg Catechism (1563), and the Canons of Dordrecht (1618-1619). These three, often referred to as the Three Forms of Unity, constitute the doctrinal standards of the Protestant Reformed Churches.
