That which is absurd and impossible, that which in any other history would be called falsehood, deception, outrage and cruelty, cannot be made reason… - Hermann Samuel Reimarus

It is always a sign that a doctrine or history possesses no depth of authenticity when one is obliged to resort to miracles in order to prove its truth. Miracles do not possess in or by themselves any principle containing a single article of faith or conclusive fact. It follows not because a prophet has performed miracles that therefore he has spoken the truth, because false prophets and magicians also performed signs and wonders, and false Christs performed miracles by which even the elect might be deceived. It follows not because Jesus restored sight to a blind man and healed a lame one, ergo God is threefold in person, ergo Jesus is a real God and man. It follows not because Jesus awakened Lazarus from death that therefore he also must have arisen from death.

The unerring signs of truth and falsehood are clear, distinct consistency and contradiction. This is also the case with revelation, in so far as that it must, in common with other truths, be free from contradiction. And just as little as miracles can prove that twice two are five or that a triangle has four angles, can a contradiction lying in the history and dogmas of Christianity be removed by any number of miracles.

If a prophecy is to be called infallible, I fairly demand that it should state beforehand legibly, clearly, and distinctly that which no man could previously have known, and that the same should thereafter take place at the time appointed, but that it should not take place because it has been predicted. If, however, such a prophecy can only be verified through allegorical interpretations of words and interpretation of words and things; if it be only composed of dark and dubious words, and the expressions it contains are commonplace, vague, and uncertain; if the matter was thought probable, or was foreseen by human cunning; if it occurs because it was predicted; if the words used refer to some other matter and are only applied to the prophecy by a quibble; if it is only written down after the event has occurred; if a prophetic book or passage is given out to be older than it is; or lastly, if the thing predicted does not take place at all, then the prophecy is either doubtful or false.
