Athanasian Creed

The Athanasian Creed, or Quicunque Vult (also Quicumque Vult), is a Christian statement of belief focused on Trinitarian doctrine and Christology. The Latin name of the creed, Quicumque vult, is taken from the opening words, "Whosoever wishes". The creed has been used by Christian churches since the sixth century. It is the first creed in which the equality of the three persons of the Trinity is explicitly stated. It differs from the Nicene-Constantinopolitan and Apostles' Creeds in the inclusion of anathemas, or condemnations of those who disagree with the creed (like the original Nicene Creed).

Widely accepted among Western Christians, including the Roman Catholic Church, the Anglican Communion, the Lutheran Churches and most liturgical Protestant denominations, the Athanasian Creed has been used in public worship less and less frequently. The creed has never gained much acceptance in liturgy among Eastern Christians.
