imperishability: the state of being free from decay, breakdown, and death
This word names a quality of being that does not wear out, rot, or come to an end. It is built by negating a Greek word for decay and ruin (phthora), so at root it means "not able to fall apart." Greek philosophers had used it for whatever stands outside the world of things that come into being and pass away: the gods, the unchanging heavens, the eternal realities behind the physical world. Jewish writers in Greek then borrowed it for the deathless future God grants the righteous, and the New Testament writers borrowed it again to describe the risen Christ and everything joined to him.
In the New Testament the word always points the same direction, even as it lands on different things. Paul uses it most for the resurrection body, the form of life God raises that can no longer break down or die. He also uses it for the future that God holds out to his people, a life of incorruption that overlaps with eternal life itself. And in a few places the same word stretches to name a quality of love or character that does not fade.
The senses below are facets of that one idea, not separate words. What ties them together is the claim that something has been lifted out of the realm of decay and death and given a permanence that belongs, finally, to God.
Nuances
Disputed
In 1 Corinthians 15:53-54 Paul places this word (imperishability) in parallel with a near-twin word for deathlessness. Whether the two name one quality stated twice for emphasis or two genuinely distinct qualities is disputed.
- majorityThe two are synonymous parallelism: Paul piles up vocabulary for force, one term stressing freedom from decay and the other freedom from death, but they describe a single transformed condition.; Anthony C. Thiselton, The First Epistle to the Corinthians (NIGTC); Gordon D. Fee, The First Epistle to the Corinthians (NICNT); David E. Garland, 1 Corinthians (BECNT)
- minorityThe technical distinction holds: deathlessness denies death, while imperishability denies substantial dissolution and is the broader, stronger quality; Paul uses both because the present body must be freed from both decay and death.; Ceslas Spicq, Theological Lexicon of the New Testament; Joseph A. Fitzmyer, commentary in the Anchor Bible series
