Chapter 20 — Part II: The Sacraments — Extreme Unction
Section 18. The Subject Must Be In Danger Of Death — In the first place, it is not to be administered to persons in sound health, according to these words of St. James: Is anyone sick amongst you? This is also proved by the fact that Extreme Unction was instituted as a remedy not only for the diseases of the soul, but also for those of the body. Now only the sick need a remedy, and therefore this Sacrament is to be administered to those only whose malady is such as to excite apprehensions of approaching death.
