"Worldly society has flowered from a selfish love which dared to despise even God, whereas the communion of saints is rooted in a love of God....This latter relies on the Lord, whereas the other boasts that it can get along by itself. The city of man seeks the praise of men, whereas the height of glory for the other is to hear God in the witness of conscience. The one lifts up its head in its own boasting; the other says to God: 'Thou art my glory, thou liftest up my head' (Ps. 3:4)."
--St. Augustine, The City of God, Book 14, Chapter 28.
