God is a concept by which we measure our pain.

The freedom or immunity from coercion in matters religious, which is the endowment of persons as individuals, is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself.

The most dangerous madmen are those created by religion, and people whose aim is to disrupt society always know how to make good use of them.

One religion is as true as another.

The nature of God is a circle, of which the center is everywhere and the circumference is nowhere.

Talk to me about the truth of religion and I’ll listen gladly. Talk to me about the duty of religion and I’ll listen submissively. But don’t come talking to me about the consolations of religion or I shall suspect that you don’t understand.

God is really only another artist. He invented the giraffe, the elephant, and the cat. He has no real style. He just goes on trying other things.

So long as one believes in God, one has the right to do the Good in order to be moral.

Whatsoever is, is in God.

Religion is by no means a proper subject of conversation in mixed company.

The wrath of the lion is the wisdom of God.

God is a complex of ideas formed by the tribe, the nation, and humanity, which awake and organize social feelings and aim to link the individual to society and to bridle the zoological individualism.

We have just enough religion to make us hate, but not enough to make us love one another.
