While just government protects all in their religious rites, true religion affords government its surest support.

I have never seen the slightest scientific proof of the religious ideas of heaven and hell, of future life for individuals, or of a personal God.

A degree of culture, and assuredly a very high one, is attained when man rises above superstitions and religious notions and fears, and, for instance, no longer believes in guardian angels or in original sin, and has also ceased to talk of the salvation of his soul.

My religious point of view is something I can't talk about. It goes against my belief system to talk publicly about my own spiritual beliefs.

After coming into contact with a religious man I always feel I must wash my hands.

You cannot drag a man's conscience before any tribunal, and no one is answerable for his religious opinions to any power on earth.
