Athanasian Creed

The Athanasian Creed — also called the Pseudo-Athanasian Creed or Quicunque Vult (or Quicumque Vult), which is both its Latin name and its opening words, meaning "Whosoever wishes" — is a Christian statement of belief focused on Trinitarian doctrine and Christology. Used by Christian churches since the early sixth century, it was the first creed to explicitly state the equality of the three hypostases of the Trinity. It differs from the Nicene-Constantinopolitan Creed and the Apostles' Creed in that it includes anathemas condemning those who disagree with its statements (as does the original Nicene Creed).

Widely accepted in Western Christianity, including by the Roman Catholic Church, Lutheran Churches (it is part of the Lutheran confessions set out in the Book of Concord), Anglican Churches, Reformed Churches, and ancient liturgical churches, the Athanasian Creed has been used in public worship less frequently, with exception of Trinity Sunday.^[1] However, part of it can be found as an "Authorized Affirmation of Faith" in the main volume of the Common Worship liturgy of the Church of England published in 2000.^[2][3] Despite falling out of liturgical use, the creed's influence on current Protestant understanding of trinitarian doctrine is clear.

Designed to distinguish Nicene Christianity from Arianism, the Athanasian Creed traditionally was recited at the Sunday Office of Prime in the Western Church. It has not been commonly used in the Eastern Church.
