Saint Cyprian on the Unity of the Catholic Church

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.

— St. Cyprian
