CCC 1513 The Apostolic Constitution Sacram unctionem infirmorum,1 following upon the Second Vatican Council,2 established that henceforth, in the Roman Rite, the following be observed:
The sacrament of Anointing of the Sick is given to those who are seriously ill by anointing them on the forehead and hands with duly blessed oil – pressed from olives or from other plants – saying, only once: “Through this holy anointing may the Lord in his love and mercy help you with the grace of the Holy Spirit. May the Lord who frees you from sin save you and raise you up.”3
