St. Augustine: "The two cities"

“WE see then that the two cities were created by two kinds of love: the earthly city was created by self-love reaching the point of contempt for God, the Heavenly City by the love of God carried as far as contempt of self. In fact, the earthly city glories in itself, the Heavenly City glories in the Lord. The former looks for glory from men, the latter finds its highest glories in the Lord. The former looks for glory from men, the latter finds its highest glory in God, the witness of a good conscience. The earthly lifts up its head in its own glory, the Heavenly City says to its God: “My glory; you lift up my head.” In the former, the lust for domination lords it over its princes as over the nations it subjugates; in the other both those put in authority and those subject to them serve one another in love, the rulers by their counsel, the subjects by obedience. The one city loves its own strength shown in its powerful leaders; the other says to its God, “I will love you, my Lord, my strength.””
