Could a miracle ever be evidence?

Near its close, John states its purpose outright: "Jesus did many other signs in the presence of his disciples, which are not written in this book; but these are written that you may believe that Jesus is the Christ."

That is a document telling the reader it is making a case, using events as the argument. Whatever else is going on, the text is not shy about what it is for.

In Mark, asked for a sign from heaven, Jesus "sighed deeply in his spirit" and said no sign would be given to this generation. The request is treated as the wrong kind of request.

So the canon contains both a book offering signs as grounds for belief and an episode in which demanding one is the error. Any account of what these texts think a miracle is for has to carry both.

In an essay first published in 1748, Hume argued that "a miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined".

From which: "no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavours to establish."

The claim is not that miracles are impossible. It is that testimony is itself only experience, and has to outweigh the uniform experience a miracle would overturn. His contemporaries read that as meaning it never could, however good the witnesses. Hume drew his own line more narrowly: no testimony could prove a miracle "so as to be the foundation of a system of religion", and he allowed that one founding no religion might be proved.

One standing objection is that the argument, applied consistently, would have blocked belief in genuinely novel phenomena that turned out to be real, because uniform experience was against those too until it was not.

Hume anticipated it in the essay itself. The Indian prince who refused to believe the first reports of frost "reasoned justly", he says, because ice was "not contrary to his experience", only unlike it. A novelty is not a violation, so the cases are not parallel.

This has been going for nearly three centuries and neither side is obviously making a mistake, which is usually the sign of a disagreement about something upstream.

If the laws of nature are exceptionless descriptions of what happens, a violation is a contradiction and the question is closed by definition. If they are descriptions of how things go when nothing intervenes, then whether anything ever intervenes is exactly what is at issue and cannot be settled by the definition.

Much of the heat in this argument comes from the two sides having already answered that, usually without saying so.

Nothing available. A repeatable miracle would be a natural phenomenon and would be studied as one. A unique one leaves testimony and the traces around it, and how much those can carry is the thing under dispute.

That is not a stalemate produced by anybody being unreasonable. It is the shape of the question, and it means a person’s verdict here is largely determined by what they thought before they arrived.

Christians do not agree on how often miracles happen. In a 2006 survey of ten countries, large majorities of Christians said miracles still occur today, and in every country most Pentecostals said they had experienced or witnessed a divine healing. The Catholic Church examines reported apparitions and similar phenomena under formal norms which, since 2024, as a rule stop short of declaring any of them supernatural.

Nor do they all keep miracles out of the argument. Catholic teaching calls the miracles of Christ and the saints "motives of credibility", which show that faith is "by no means a blind impulse of the mind", and says of Jesus' own that they "are not intended to satisfy people's curiosity or desire for magic".

The central claim is one event, the resurrection, and Paul does list its witnesses. But he also writes that "if Christ has not been raised, then our preaching is in vain and your faith also is in vain". That is a different sort of claim from a wonder offered as proof, and the difference is one way to read why Mark can have Jesus decline to provide one.

Hume’s argument has been in print since 1748 and the Stanford Encyclopedia’s survey of the literature is a catalogue of live positions rather than a verdict: what a law of nature is, what counts as violating one, and how to weigh testimony are all still being argued.

Which does not tell you who is right. It does mean the argument, sharp as it is, has not settled the question even among the philosophers who know it best. Whether it is what settles it for anyone else, and what does the work if not, are not things this page has a source for.
