Here are a few quotes from St. John Vianney's homilies that highlight the beauty of this sacrament and offers encouragement to the weary soul.
It is a beautiful thought, my children, that we have a Sacrament which heals the wounds of our soul!
My children, we cannot comprehend the goodness of God towards us in instituting this great Sacrament of Penance. If we had had a favor to ask of Our Lord, we should never have thought of asking Him that. But He foresaw our frailty and our inconstancy in well-doing, and His love induced Him to do what we should not have dared to ask.
My Children, if [a person has] a serious illness, if it is a dangerous wound, he must have the doctor; after the doctor come the remedies. In the same way, when we have fallen into any grievous sin, we must have recourse to the doctor, that is the priest; and to the remedy, that is confession.
God makes a greater speed to pardon a penitent sinner than a mother to snatch her child out of the fire.
