The Bible is acknowledged as the ‘ground’ on which any expression of Christian faith must be founded.
The Ancient Creeds
Anglicans, like many other Christians, formally profess their faith in the words of the historic Christian creeds, which were formulated in the early centuries of the Christian Church. (The word ‘creed’ comes from the Latin ‘credo’ = ‘I believe’)
The Apostles’ Creed and the Nicene Creed are used very regularly in Anglican worship, the Athanasian Creed is used in worship less often, but is considered to set out the classic understanding of key Christian doctrines about the nature of God and the person of Jesus Christ.
