Original sin is that thing about man which makes him capable of conceiving of his own perfection and incapable of achieving it.
Reinhold NiebuhrWe take, and must continue to take, morally hazardous actions to preserve our civilization. We must exercise our power. But we ought neither to believe that a nation is capable of perfect disinterestedness in its exercise, nor become complacent about a particular degree of interest and passion which corrupt the justice by which the exercise of power is legitimatized.
Reinhold NiebuhrNow the ordinary Protestant, Jew or Secularist has a stereotype about Catholicism. It consists of Spanish Catholicism, Latin-American Catholicism and, let us say, a Catholicism of O'Connor's "Great Hurrah." Now there are types of Catholicism like that but this doesn't - this doesn't do justice to the genuine relation that Catholicism has had to Democratic Society.
