This is the final anointing when bodily recovery is impossible and death is imminent. From the early Middle Ages until after the Second Vatican Council the sacrament was administered, within the Latin Church, only when death was approaching and, in practice, bodily recovery was not ordinarily looked for, giving rise, as mentioned above to the name “Extreme Unction” (i.e. final anointing). The extraordinary form of the Roman Rite includes anointing of seven parts of the body: sight, hearing, smell, taste, touch, walking, carnal delectation.
As administered in the Western Church today according to the rite of the Roman Ritual, the sacrament consists in the unction with oil [OI], specially blessed by the bishop, of the organs of the five external senses (eyes, ears, nostrils, lips, hands), of the feet, and, for men (where the custom exists and the condition of the patient permits of his being moved), of the loins or reins; and in the following form repeated at each unction with mention of the corresponding sense or faculty: “Through this holy unction and His own most tender mercy may the Lord pardon thee whatever sins or faults thou hast committed [quidquid deliquisti] by sight [by hearing, smell, taste, touch, walking, carnal delectation]”. The unction of the loins is generally, if not universally, omitted in English-speaking countries, and it is of course everywhere forbidden in case of women. To perform this rite fully takes an appreciable time, but in cases of urgent necessity, when death is likely to occur before it can be completed, it is sufficient to employ a single unction (on the forehead, for instance) with the general form: “Through this holy unction may the Lord pardon thee whatever sins or faults thou hast committed.” By the decree of 25 April, 1906, the Holy Office has expressly approved of this form for cases of urgent necessity.
