“To believe that God created a plurality of worlds, at least as numerous as what we call stars, renders the Christian faith at once little and ridiculous; and scatters it in the mind like feathers in the air.”

“It is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing, or in disbelieving, it consists in professing to believe what he does not believe.”

“But the resurrection of a dead person from the grave, and his ascension through the air, is a thing very different, as to the evidence it admits of, to the invisible conception of a child in the womb. The resurrection and ascension, supposing them to have taken place, admitted of public and ocular demonstration, like that of the ascension of a balloon, or the sun at noon day, to all Jerusalem at least. A thing which everybody is required to believe, requires that the proof and evidence of it should be equal to all, and universal; and as the public visibility of this last related act was the only evidence that could give sanction to the former part, the whole of it falls to the ground, because that evidence never was given. Instead of this, a small number of persons, not more than eight or nine, are introduced as proxies for the whole world, to say they saw it, and all the rest of the world are called upon to believe it. But it appears that Thomas did not believe the resurrection; and, as they say, would not believe without having ocular and manual demonstration himself. So neither will I; and the reason is equally as good for me, and for every other person, as for Thomas.”

“Of all the systems of religion that ever were invented, there is no more derogatory to the Almighty, more unedifying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity. Too absurd for belief, too impossible to convince, and too inconsistent for practice, it renders the heart torpid or produces only atheists or fanatics. As an engine of power, it serves the purpose of despotism, and as a means of wealth, the avarice of priests, but so far as respects the good of man in general it leads to nothing here or hereafter.”

“The Christian religion is a parody on the worship of the sun, in which they put a man called Christ in the place of the sun, and pay him the adoration originally payed to the sun.”

“The mind once enlightened cannot again become dark.”

“I do not believe in the creed professed by the Jewish church, by the Roman church, by the Greek church, by the Turkish church, by the Protestant church, nor by any church that I know of. My own mind is my own church.All national institutions of churches, whether Jewish, Christian, or Turkish, appear to me no other than human inventions set up to terrify and enslave mankind, and monopolize power and profit.”
