The Star That Cannot Find Its Way Home

Jude 1:13 · Rare or unique word · 2026-09-21

κύματα ἄγρια θαλάσσης ἐπαφρίζοντα τὰς ἑαυτῶν αἰσχύνας ἀστέρες πλανῆται οἷς ὁ ζόφος τοῦ σκότους εἰς αἰῶνα τετήρηται

Raging waves of the sea, foaming out their own shame; wandering stars, to whom is reserved the blackness of darkness for ever.

The English reader hears 'wandering stars' and pictures ordinary astronomy — a poetic flourish comparing false teachers to shooting stars or errant planets.

The Greek word is planetes (πλανῆται) — and it is the only time this word appears in the entire New Testament. It gives us our word 'planet,' because the ancient Greeks called the wandering lights in the sky planetes asteres precisely because, unlike the fixed stars, they had no settled course. Jude reaches for this single, unrepeated word to name false teachers: they are not stars that guide, like the one that led the magi, but stars with no fixed orbit, no reliable path, giving light that leads nowhere in particular.

A word used only once forces the reader to slow down and ask why no other word would do. Jude has already named these men as hidden reefs, waterless clouds, fruitless trees, wild waves foaming out their own shame. Planetes crowns the list: it names not just their sin but their unreliability as guides. A star you steer by must hold still. A wandering star, however bright, will run you onto the rocks — which is exactly what Jude has just pictured with the raging sea.

Set against this one wandering word stands the whole rest of Scripture's testimony to a God who does not wander. He is the Father of lights 'with whom is no variableness, neither shadow of turning' (James 1:17) — the true North against which every planetes is finally exposed as errant. Jude's readers were not left directionless; the letter that names the wanderers also ends by naming the One 'able to keep you from falling.' The same darkness reserved for the wandering stars is the darkness God's own steadfastness never enters. To worship rightly is to fix on a light that does not move.
