“OUR most merciful Redeemer, Who would have His servants at all times provided with salutary remedies against all the weapons of all their enemies: as in the other sacraments He prepared the greatest aids whereby during life Christians may preserve themselves whole from every grievous spiritual evil, so did He guard the close of life with a most firm defence, viz., the Sacrament of Extreme Unction” (Council of Trent, sess. xiv., Extr. Unct.). This sacrament has been known under various other names: e.g. “Oil of blessing” (oleum benedictionis); “Holy Oil” (oleum sanctum, ἁγίον ἔλαιον); “the Sacrament of Sacred Unction” (sacramentum sancta unctionis); and also among the Greeks, εὐχέλαιον (oil with prayer).
