To CHANGE FORM — meta ('change') + morphē ('form'); the root of English 'metamorphosis.' Matthew 17:2 puts it in the PASSIVE: he WAS transfigured, something done to him rather than performed by him. ⚠ English hides a connection the Greek makes plainly, because the New Testament uses this same verb only twice more and both times of ordinary Christians: 'be TRANSFORMED by the renewing of your mind' (Romans 12:2) and 'we all… are being TRANSFORMED into the same image from glory to glory' (2 Corinthians 3:18) — the second inside a passage about Moses' shining face and the veil over it, which is exactly the imagery of the mountain. Every English shelf version reads 'transfigured' here (from the Latin transfiguratus) and 'transformed' there, so the reader is not told they are one word. The related noun morphē is Philippians 2:6-7's 'form of God' / 'form of a slave.' → first discussed at Matt 17:2
