Millennium

The episode's title is taken from 1 Corinthians 13: "When I was a child, I spoke as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass darkly; but then face to face. Now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity." The Biblical passage references man's knowledge of God, expressing the idea that mortal man can know only an obscured reflection of God and that in paradise the two can at last be brought face to face.
