The adjective ἰσάγγελος (literally "equal to angels") describes someone having angelic qualities or status. Luke 20:36 uses it in Jesus's teaching about the resurrection: those who attain the resurrection "cannot die anymore, for they are equal to angels and are sons of God, being sons of the resurrection." The comparison emphasizes immortality and transformation: resurrected believers will be like angels in that they don't die and don't marry. The word doesn't mean believers become angels but share certain angelic characteristics. Translations render it "like angels" or "equal to angels," preserving the comparison to angelic immortality and nature.
