Miracle

← Encyclopedia

A miracle is an event ascribed to divine power and understood to fall outside the ordinary course of nature — a healing that medicine cannot explain, a storm stilled, the dead raised. The word descends from the Latin miraculum, a thing to be wondered at, and the wonder is essential to it: a miracle is not merely unusual but pointed, taken to mean something about the will behind it.

The scriptures that shaped the Western idea rarely use a single word. The Hebrew Bible speaks of signs and wonders; the Greek of the Gospels favors sēmeion, a sign, and dynamis, an act of power, far more often than any term for a breach of natural law. That vocabulary matters, because in those texts the marvel is secondary to what it points at. A miracle in this register is less a violation than a disclosure — a moment in which an order usually hidden becomes briefly legible.

The sharper definition, the one most debated since, came later. Medieval theologians worked to distinguish the genuine miracle, worked by God, from the merely wonderful or the demonic counterfeit. Augustine held that nothing is truly contrary to nature, only contrary to nature as it is known; Aquinas ranked miracles by how far they exceeded created powers, reserving the highest for what God alone could do. Within these traditions the miracle was never arbitrary. It served revelation, authenticated a messenger, answered a prayer — always a sign read inside a story already believed.

The modern argument turns on evidence rather than on God’s power. In his essay “Of Miracles” (1748), David Hume framed the question as one of testimony: a miracle is by definition the most improbable of events, since uniform experience stands against it, and no human report is reliable enough to make believing the report more reasonable than doubting the witness. The argument does not deny that miracles could occur; it claims that one could never have sufficient grounds to credit a particular account of one. The wager has been contested ever since — over whether it begs the question, over what “uniform experience” can be assumed — and it set the terms for nearly every later discussion.

Traditions hold the matter in their own ways. Catholic practice still examines reported cures with medical scrutiny in the causes of saints; many Protestant currents have read the age of biblical miracles as closed, while Pentecostal and charismatic movements expect them to continue. Islamic theology distinguishes the prophetic muʿjiza, the sign confirming a messenger, from the karāma, the lesser grace granted a saint. The thread common to these is not a shared metaphysics but a shared use: the event is taken to carry a meaning, and the dispute is finally over how that meaning may be known.

What the long argument circles is a single tension. To call something a miracle is to claim both that it happened and that it could not have happened on its own — and the second claim is the one no observation settles. The marvel can be recorded; the hand behind it cannot. That gap is where the question has stayed.
