The Church is an enclosure. If you are within, the wolf does not enter; but if you leave, the beasts will seize you. Do not distance yourself from the Church; there is nothing mightier than the Church. The Church is your hope. The Church is your salvation. The Church is higher than the heavens. The Church is harder than stone. The Church is wider than the world. The Church never grows old but always renews itself.
–Saint John Chrysostom (347-407)
