“There are in the sight of God only two classes of people; the once-born and the twice-born; those who are born of woman, and those who are born of the spirit of God.  The first are just men; the second are children of God; the first are humanists, the second are Christians; the first are of the world, the second are of the kingdom of God.”  Archbishop Fulton Sheen (The Mystical Body of Christ)
