|Revelation when applied to religion, means something communicated immediately from God to man. No one will deny or dispute the power of the Almighty to make such a communication if he pleases. But admitting, for the sake of a case, that something has been revealed to a certain person, and not revealed to any other person, it is revelation to that person only. When he tells it to a second person, a second to a third, a third to a fourth, and so on, it ceases to be a revelation to all those persons. It is revelation to the first person only, and hearsay to every other, and, consequently, they are not obliged to believe it. It is a contradiction in terms and ideas to call anything a revelation that comes to us at second hand, either verbally or in writing.
– Thomas Paine (1737-1809)
