Chapter 20 — Part II: The Sacraments — Extreme Unction
Section 21. The Person Anointed Must Have Attained The Use Of Reason — Furthermore, all those who have not the use of reason are not fit subjects for this Sacrament; and likewise children who, having committed no sins, do not need the Sacrament as a remedy against the remains of sin. The same is true of idiots and insane persons, unless they give indications in their lucid intervals of a disposition to piety, and express a desire to be anointed. To persons who from their birth never enjoyed the use of reason this Sacrament is not to be administered; but if a sick person, while in the possession of his faculties, expresses a wish to receive Extreme Unction and afterwards becomes delirious he is to be anointed.
