Anointing of the Sick is the second sacrament of healing. In this sacrament a priest anoints the sick with oil blessed specifically for that purpose. “The anointing of the sick can be administered to any member of the faithful who, having reached the use of reason, begins to be in danger by reason of illness or old age” (canon 1004; cf. CCC 1514). A new illness or a worsening of health enables a person to receive the sacrament a further time.
When, in the Western Church, the sacrament was conferred only on those in immediate danger of death, it came to be known as “Extreme Unction”, i.e. “Final Anointing”, administered as one of the Last Rites. The other Last Rites are Confession (if the dying person is physically unable to confess, at least absolution, conditional on the existence of contrition, is given), and the Eucharist, which when administered to the dying is known as “Viaticum”, a word whose original meaning in Latin was “provision for a journey”.
