Metaschematizō
Metaschematizō (μετασχηματίζω) — meta (change) + schēma (outward fashion). To change the outward form. Paul uses it for a real transformation (Phil 3:21) and, pointedly, for its counterfeit — false apostles who metaschematizō, masquerade, as servants of light (2 Cor 11:13-15): the mask changed, the inside untouched — the surface-work of the whitewashed tomb (Matthew 23:27).
