Can. 998 The anointing of the sick, by which the Church commends to the suffering and glorified Lord the faithful who are dangerously ill so that he may support and save them, is conferred by anointing them with oil and pronouncing the words prescribed in the liturgical books.
CHAPTER II : THE MINISTER OF ANOINTING OF THE SICK
Can. 1003 §1 Every priest, but only a priest,** can validly administer the anointing of the sick.**
§2 All priests to whom has been committed the care of souls, have the obligation and the right to administer the anointing of the sick to those of the faithful entrusted to their pastoral care. For a reasonable cause, any other priest may administer this sacrament if he has the consent, at least presumed, of the aforementioned priest.
§3 Any priest may carry the holy oil with him, so that in a case of necessity he can administer the sacrament of anointing of the sick.
CHAPTER III : THOSE TO BE ANOINTED
Can. 1004 §1 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 of death by reason of illness or old age.
§2 This sacrament can be repeated if the sick person, having recovered, again becomes seriously ill or if, in the same illness, the danger becomes more serious.
Can. 1005 If there is any doubt as to whether the sick person has reached the age of reason, or is dangerously ill, or is dead, this sacrament is to be administered.
Can. 1006 This sacrament is to be administered to the sick who, when they were in possession of their faculties, at least implicitly asked for it.
Can. 1007 The anointing of the sick is not to be conferred upon those who obstinately persist in a manifestly grave sin.
