The International Conference of Reformed Churches (ICRC) is a federation of Reformed or Calvinist churches across the world. The ICRC is founded in 1981. The ICRC convenes international meetings every four years. Its theology is more conservative than the larger World Communion of Reformed Churches and is similar to that of the World Reformed Fellowship. The participating churches endorse the Reformed confessions (Heidelberg Catechism, Belgic Confession, Canons of Dort and the Westminster Confession of Faith).
