One religion is as true as another.

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

The various modes of religion which prevailed in the Roman world were all considered by the people as equally true, by the philosophers equally false, and by the magistrate as equally useful.

Whatsoever is, is in God.

If God did not exist, it would be necessary to invent him.

Educate people without religion and you make them but clever devils.

Reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.

Religion! How it dominates man’s mind, how it humiliates and degrades his soul. God is everything, man is nothing, says religion. But out of that nothing God has created a kingdom so despotic, so tyrannical, so cruel, so terribly exacting that naught but gloom and tears and blood have ruled the world since gods began.

The important thing, I think, is not to be bitter. You know, if it turns out that there is a God, I don’t think that he’s evil. I think that the worst thing you could say about him is that basically he’s an underachiever. After all, you know, there are worse things in life than death.

I can’t see (or feel) the conflict between love and religion. To me they’re the same thing.

Among all nations, through the darkest polytheism glimmer some faint sparks of monotheism.

God is a concept by which we measure our pain.
