CCC 1511

The Church believes and confesses that among the seven sacraments there is one especially intended to strengthen those who are being tried by illness, the Anointing of the Sick:

This sacred anointing of the sick was instituted by Christ our Lord as a true and proper sacrament of the New Testament. It is alluded to indeed by Mark, but is recommended to the faithful and promulgated by James the apostle and brother of the Lord.¹²⁴ Council of Trent (1551): DS 1695DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); cf. Mk 6:13; Jas 5:14-15.
