Chapter 19 — Part II: The Sacraments — Penance
Section 159. Nor does this lessen the most perfect and superabundant satisfaction of Christ our Lord, but, on the contrary, renders it still more conspicuous and illustrious. For the grace of Christ is seen to abound more, inasmuch as it communicates to us not only what He merited and paid of Himself alone, but also what, as Head, He merited and paid in His members, that is, in holy and just men. Hence it can be seen how such great weight and dignity belong to the good actions of the pious. For Christ our Lord continually infuses His grace into the devout soul united to Him by charity, as the head to the members, or as the vine through the branches. This grace always precedes, accompanies and follows our good works, and without it we can have no merit, nor can we at all satisfy God.
