# The Age of Reason/Part I/Chapter XVI

But, in the midst of those reflections, what are we to think of the christian system of faith that forms itself upon the idea of only one world, and that of no greater extent, as is before shown, than twenty-five thousand miles. An extent which a man, walking at the rate of three miles an hour for twelve hours in the day, could he keep on in a circular direction, would walk entirely round in less than two years. Alas! what is this to the mighty ocean of space, and the almighty power of the Creator!
From whence then could arise the solitary and strange conceit that the Almighty, who had millions of worlds equally dependent on his protection, should quit the care of all the rest, and come to die in our world, because, they say, one man and one woman had eaten an apple! And, on the other hand, are we to suppose that every world in the boundless creation had an Eve, an apple, a serpent, and a redeemer? In this case, the person who is irreverently called the Son of God, and sometimes God himself, would have nothing else to do than to travel from world to world, in an endless succession of death, with scarcely a momentary interval of life.
It has been by rejecting the evidence, that the word, or works of God in the creation, affords to our senses, and the action of our reason upon that evidence, that so many wild and whimsical systems of faith, and of religion, have been fabricated and set up. There may be many systems of religion that so far from being morally bad are in many respects morally good: but there can be but One that is true; and that one necessarily must, as it ever will, be in all things consistent with the ever existing word of God that we behold in his works. But such is the strange construction of the christian system of faith, that every evidence the heavens affords to man, either directly contradicts it or renders it absurd.
It is possible to believe, and I always feel pleasure in encouraging myself to believe it, that there have been men in the world who persuaded themselves that what is called a pious fraud, might, at least under particular circumstances, be productive of some good. But the fraud being once established, could not afterwards be explained; for it is with a pious fraud as with a bad action, it begets a calamitous necessity of going on.
The persons who first preached the christian system of faith, and in some measure combined with it the morality preached by Jesus Christ, might persuade themselves that it was better than the heathen mythology that then prevailed. From the first preachers the fraud went on to the second, and to the third, till the idea of its being a pious fraud became lost in the belief of its being true; and that belief became again encouraged by the interest of those who made a livelihood by preaching it.
But though such a belief might, by such means, be rendered almost general among the laity, it is next to impossible to account for the continual persecution carried on by the church, for several hundred years, against the sciences, and against the professors of science, if the church had not some record or tradition that it was originally no other than a pious fraud, or did not foresee that it could not be maintained against the evidence that the structure of the universe afforded.
