Reinhold Niebuhr
Man's capacity for justice makes democracy possible, but man's inclination to injustice makes democracy necessary.
Family life is too intimate to be preserved by the spirit of justice. It can be sustained by a spirit of love which goes beyond justice.
Life is a battle between faith and reason in which each feeds upon the other, drawing sustenance from it and destroying it.
The final wisdom of life requires not the annulment of incongruity but the achievement of serenity within and above it.
There are historic situations in which refusal to defend the inheritance of a civilization, however imperfect, against tyranny and aggression may result in consequences even worse than war.
God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed and the wisdom to distinguish the one from the other.
God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.
