My personal attitude toward atheists is the same attitude that I have toward Christians, and would be governed by a very orthodox text: "By their fruits shall ye know them." I wouldn't judge a man by the presuppositions of his life, but only by the fruits of his life. And the fruits - the relevant fruits - are, I'd say, a sense of charity, a sense of proportion, a sense of justice. And whether the man is an atheist or a Christian, I would judge him by his fruits, and I have therefore many agnostic friends.
Reinhold NiebuhrThe tendency to claim God as an ally for our partisan value and ends is the source of all religious fanaticism.
Reinhold NiebuhrThe final test of religious faith... is whether it will enable men to endure insecurity without complacency or despair, whether it can so interpret the ancient verities that they will not become mere escape hatches from responsibilities but instruments of insights into what civilization means.
