A creed is the set of beliefs that defines a person's religion, and can therefore be used as a synonym for religion in general (e.g. 'Membership is open to people of all creeds').
In Christianity, the creed is a part of the service liturgy where the congregation recites a list of their beliefs. There are several different creeds, including the Apostles' Creed and the Nicene Creed, although all include the basic tenets of Christianity such as belief in God the Father, God the Son and the Holy Spirit.[1]
