The essence of man is his freedom. Sin is committed in that freedom. Sin can therefore not be attributed to a defect in his essence. It can only be understood as a self-contradiction, made possible by the fact of his freedom but not following necessarily from it.
Reinhold NiebuhrUltimately freedom is necessary for a society, because every despotic society - for instance, the Russian society - lives on the basis of a rather implausible dogma - the Marxist dogma of world redemption through Communism.
Reinhold NiebuhrWhen a church reaches up beyond its group and tries to enforce its standards upon a society that doesn't accept these standards, and perhaps for good reason, perhaps for bad reason, but anyway this is the problem we face in pluralistic society, that not necessarily every standard that every church tries to enforce upon the society is from the society's standpoint a good standard.
