Chapter 19 — Part II: The Sacraments — Penance
Section 166. As this life is chequered by many and various afflictions, the faithful are to be particularly reminded that those who patiently bear all the trials and afflictions coming from the hand of God acquire abundant satisfaction and merit; whereas those who suffer with reluctance and impatience deprive themselves of all the fruits of satisfaction, merely enduring the punishment which the just judgment of God inflicts upon their sins.
