"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.”

“Jesus himself could not perform miracles where the people had not faith beforehand, and when sensible men, the learned and rulers of those times, demanded of him a miracle which could be submitted to examination, he, instead of granting the request, began to upbraid them; so that no man of this stamp could believe in him. It was not until thirty to sixty years after the death of Jesus, that people began to write an account of the performance of these miracles, in a language which the Jews in Palestine did not understand. And this was at a time when the Jewish nation was in a state of the greatest disquietude and confusion, and when very few of those who had known Jesus were still alive. Nothing then was easier for them than to invent as many miracles as they pleased, without fear of their writings being readily understood or refuted. It had been impressed upon all converts from the beginning that it was both advantageous and soul-saving to believe, and to put the mind captive under the obedience of faith; and consequently there was as much credulity among them as there was "pia fraud" or "deception from good motives" among their teachers; and both of these, as is well known, prevailed in the highest degree in the early Christian church.”

“In short, I may affirm that one cannot refer to a single quoted prophecy that is not false; or if you would have me speak more mildly, I will only say that they are all ambiguous and doubtful, and are not to be accepted from writers who trifle with things and words.”

“It was then clearly not the intention or the object of Jesus to suffer and to die, but to build up a worldly kingdom, and to deliver the Israelites from bondage.”

“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.”

“By unessential things in reference to religion I mean first of all, the miracles, to which nevertheless such particular importance is attached by the Christian religion. No one can affirm that miracles of themselves establish a single article of faith. If we granted that articles of faith carried with them conviction and inherent credibility, how should we dare to require miracles in order to believe them? If we granted that the resurrection had been proved to be true by the most undoubted and unanimous witnesses, as in all fairness it ought to be, we could surely believe it without any assistant miracle. If we granted that Christ really did return in the clouds of Heaven, as according to promise he ought to have done, we should certainly want no miracles to prove it.”
