The document discusses creeds and their purpose and history. It explains that creeds are statements of basic Christian beliefs meant to unite churches and protect against heresy. The Apostles' Creed originated in the 2nd century and the Nicene Creed was formulated in the 4th century in response to the Arian heresy, which denied the divinity of Christ. The Nicene Creed used the term "homoousios" or "consubstantial" to affirm Christ's oneness in being with God the Father. Creeds were meant to standardize doctrine but some argue they now hinder the mission of the church in a postmodern age.
