Chapter 17 — Part II: The Sacraments — Confirmation
Section 42. The Anointing Of The Forehead — The forehead, then, of the persons to be confirmed is anointed with sacred chrism; for by this Sacrament the Holy Spirit infuses Himself into the souls of the faithful, and increases in them strength and fortitude to enable them, in the spiritual contest, to fight manfully and to resist their most wicked foes. Wherefore it is indicated that they are to be deterred by no fear or shame, the signs of which appear chiefly on the forehead, from the open confession of the name of Christ.
