"Ecumenical creeds" is an umbrella term used in the western church to refer to the Nicene Creed, the Apostles' Creed, and the Athanasian Creed. The ecumenical creeds are also known as the universal creeds. These creeds are accepted by almost all mainstream Christian denominations in the western church, including the Roman Catholic Church, Anglican churches and Lutheran churches. A creed by definition is a summary or statement of what one believes it originates from the Latin credo meaning "I Believe." (Introduction by Wikipedia)
