The sacrament of the Anointing of the Sick is celebrated communally at Mass twice a year, or by appointment.
A SACRAMENT OF HEALING
The Anointing of the Sick “is not a sacrament for those
only who are at the point of death. Hence as soon as
anyone of the faithful begins to be in danger of death
from sickness or old age, the fitting time to receive this
sacrament has certainly already arrived.”
