Here’s the Patron Saint of Priest counseling on confession:
CHAPTER 17 : Catechism on Confession
MY CHILDREN, as soon as ever you have a little spot upon your soul, you must do like a person who has a fine globe of glass, which he keeps very carefully. If this globe has a little dust on it, he wipes it with a sponge the moment he perceives it, and there is the globe clear and brilliant. In the same way, as soon as you perceive a little stain on your soul, take some holy water with respect, do one of those good works to which the remission of venial sins is attached - an alms, a genuflection to the Blessed Sacrament, hearing a Mass. My children, it is like a person who has a slight illness; he need not go and see a doctor, he may cure himself without. If he has a headache, he need only go to bed; if he is hungry, he has only to eat. But if it is 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.
My children, we cannot comprehend the goodness of God towards us in instituting this great Sacrament of Penance. If we had had a favour 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. If one said to those poor lost souls that have been so long in Hell, "We are going to place a priest at the gate of Hell: all those who wish to confess have only to go out, " do you think, my children, that a single one would remain? The most guilty would not be afraid of telling their sins, nor even of telling them before all the world. Oh, how soon Hell would be a desert, and how Heaven would be peopled! Well, we have the time and the means, which those poor lost souls have not. And I am quite sure that those wretched ones say in Hell, “O accursed priest! if I had never known you, I should not be so guilty!”
It is a beautiful thought, my children, that we have a Sacrament which heals the wounds of our soul! But we must receive it with good dispositions. Otherwise we make new wounds upon the old ones. What would you say of a man covered with wounds who is advised to go to the hospital to show himself to the surgeon? The surgeon cures him by giving him remedies. But, behold! this man takes his knife, gives himself great blows with it and makes himself worse than he was before. Well, that is what you often do after leaving the confessional.
My children, some people make bad confessions without taking any notice of it. These persons say, "I do not know what is the matter with me:’ . . . They are tormented, and they do not know why. They have not that agility which makes one go straight to the good God; they have something heavy and weary about them which fatigues them. My children, that is because of sins that remain, often even venial sins, for which one has some affection. There are some people who, indeed, tell everything, but they have no repentance; and they go at once to Holy Communion. Thus the Blood of Our Lord is profaned! They go to the Holy Table with a sort of weariness. They say, "Yet, I accused myself of all my sins. . . I do not know what is the matter with me. " There is an unworthy Communion, and they were hardly aware of it!
