The Bread With No Namea word that occurs once, and no one has settled what it means

Say the Lord's Prayer and you will pass, without a pause, over one of the strangest words in the Greek language. ἐπιούσιον (epioúsion) — the adjective attached to the bread — occurs, in the whole of surviving ancient Greek literature, essentially here alone: in Matthew's version of the prayer, in Luke's, and in the Didache, which is simply quoting the prayer. It is found in no philosopher, no play, no letter, no shopping list. Origen of Alexandria — a native Greek speaker writing around 233 AD — already noticed this, and said plainly that the word is used by no Greek writer and in no common speech: it looks, he wrote, as if the Evangelists coined it (On Prayer 27.7).

A word coined for a prayer, occurring almost nowhere else, is a word with no context to fix its meaning. And so, for nineteen centuries, no one has been able to agree what it asks for. The rest of this page is an instrument for watching the meaning fork — and for watching the fork survive, verbatim, into the Bibles on the shelf.

I Even the two Gospels differ — but not on this

Instrument · Matthew and Luke, side by side, in Greek

The prayer reaches us in two Gospels, and they are not identical. Watch the verb and the time-word change between them — and watch the one word that does not change.

Matthew's δὸς … σήμερον is a single “give … today” (the aorist, undefined in aspect); Luke's δίδου … τὸ καθ’ ἡμέραν is a continuous “keep giving … day by day.” The frame around the bread shifts. The word for the bread itself — ἐπιούσιον — stands unmoved in both. Whatever it means, both Evangelists reached for the same impossible word.

II The translator who couldn't decide

Instrument · Jerome's Vulgate, Matthew vs Luke

Around 383–405 AD, Jerome rendered the Bible into Latin — the version the entire Latin West would read for a thousand years. Faced with ἐπιούσιον, he did something extraordinary: he translated the same Greek word two different ways, in the same work, in the two tellings of the same prayer. Toggle between them.

In Matthew he coined a brand-new Latin word — supersubstantialem, “super-substantial,” a piece-for-piece calque of ἐπί (super-) + οὐσία (ousia, substance/being). In Luke, three verses of a nearly identical prayer, he wrote the ordinary cotidianum — “daily.” The Douay-Rheims Bible, made faithfully from Jerome's Latin, carried the split straight into English: “supersubstantial bread” in Matthew, “daily bread” in Luke — and printed a footnote at Matthew admitting that “the same word” is rendered “daily” in Luke. (The original 1582 Rheims wording was “Give vs to day our supersubstantial bread”; the familiar “this day” is Bishop Challoner's later revision, shown above.) The translator's uncertainty is not hidden in the margins of scholarship. It is stamped into the text of the prayer itself.

III Four ways to cut the word open

Instrument · pick a derivation; watch the petition change

Because the word has no other occurrences to anchor it, its meaning is argued from its parts — and the parts can be assembled more than one way. Each reading gives a different prayer. Choose one.

All four are defensible; none is decisive. The standard lexicon of New Testament Greek (Bauer–Danker) lists the competing derivations and declines to settle the question — because etymology cannot. The word was built to reach past the everyday: whether it reaches toward tomorrow, toward subsistence, or toward the super-essential bread of the Eucharist depends on which seam you cut along, and the seam is invisible.

The most-recited sentence in the Western world contains a word whose meaning was lost before the ink was dry.

IV The fork, on the shelf

Instrument · the petition across the public-domain English Bibles

Here is the whole English tradition of Matthew 6:11, verbatim. The reading a Bible gives depends on which text it was translated from. Watch what happens to the one Bible made from Jerome's Latin.

The pattern is the same one that put horns on Michelangelo's Moses: an ambiguity the original left open is closed by a translator, and everything downstream inherits the choice. Every English Bible made from the Greek reads daily. Every “substance” reading, without exception, comes from Jerome's Latin — and where it appears it re-enacts his own fork: the Wycliffite Earlier Version and the Douay–Rheims both keep “substance” in Matthew and revert to “daily” in Luke, exactly as the Vulgate does. But the Latin does not compel the choice: the Wycliffite Later revision (Purvey) quietly normalised even Matthew to “daily.” The bread with no name is given a different name by every hand that carries it — and the hands do not agree, not even two revisions of the same English Bible.

V The bread of tomorrow

There is one more witness, and it is the reason many modern scholars lean toward “tomorrow.” Jerome himself left a note. In his Commentary on Matthew, at this very verse, he wrote that in the lost Gospel according to the Hebrews he had found, in place of supersubstantialem, the Aramaic word mahar (מחר) — “of tomorrow.” “So that the sense is,” he wrote, “our bread of tomorrow — that is, of the future — give us today.” The man who coined supersubstantialem for Matthew, and wrote cotidianum for Luke, recorded a third answer in his own commentary and did not choose between them either. If ἐπιούσιον is a Greek coinage straining to carry an Aramaic “tomorrow,” it is translationese — a word invented at the seam between two languages, and stranded there.
