The Age of Reason by Thomas Paine

The New Testament, they tell us, is founded upon the prophecies of the Old; if so, it must follow the fate of its foundation.

As it is nothing extraordinary that a woman should be with child before she was married, and that the son she might bring forth should be executed, even unjustly, I see no reason for not believing that such a woman as Mary, and such a man as Joseph, and Jesus, existed; their mere existence is a matter of indifference, about which there is no ground either to believe or to disbelieve, and which comes under the common head of, "It may be so, and what then? " The probability however is that there were such persons, or at least such as resembled them in part of the circumstances, because almost all romantic stories have been suggested by some actual circumstance; as the adventures of Robinson Crusoe, not a word of which is true, were suggested by the case of Alexander Selkirk.
