One religion is as true as another.

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

The wrath of the lion is the wisdom of God.

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

I believe in an America where the separation of church and state is absolute, where no Catholic prelate would tell the president (should he be a Catholic) how to act and no Protestant minister would tell his parishioners for whom to vote.

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.

Without doubt God is the universal moving force, but each being is moved according to the nature that God has given it. He directs angels, man, animals, brute matter, in sum all created things—but each according to its nature—and man having been created free, he is freely led. This rule is truly the eternal law and in it we must believe.

To doubt everything or to believe everything are two equally convenient solutions; both dispense with the need for thought.

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.

An irreligious man is not one who denies the gods of the majority, but one who applies to the gods the opinions of the majority. For what most men say about the gods are not ideas derived from sensation, but false opinions, according to which the greatest evils come to the wicked, and the greatest blessings come to the good from the gods.

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.

The Church says that the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in the shadow than in the Church.
