You cannot have God for your Father if you do not have the Church for your mother…. God is one and Christ is one, and his Church is one; one is the faith, and one is the people cemented together by harmony into the strong unity of a body…. If we are the heirs of Christ, let us abide in the peace of Christ; if we are the sons of God, let us be lovers of peace.
-- Saint Cyprian of Carthage, from "The Unity of the Catholic Church"
