Paul Tillich Quote

The Great Commandment demands of everyone the total love of God and the love one's neighbour according to the measure of man's natural self-affirmation. If love is emotion, how can it be demanded? Emotions cannot be demanded. We cannot demand them of ourselves. If we try, something artificial is produced which shows the traits of what had to be suppressed in its production. Repentance, intentionally produced, hides self-complacency in perversion. Love, intentionally produced, shows indifference or hostility in perversion. The means: love as an emotion cannot be commanded. Either love is something other than emotion or the Great Commandment is meaningless.
