Diary of Saint Maria Faustina
113 And again, I would like to say three words to the soul that is determined to strive for sanctity and to derive fruit; that is to say, benefit from confession. First [word] — complete sincerity and openness. Even the holiest and wisest confessor cannot forcibly pour into the soul what he desires if it is not sincere and open. An insincere, secretive soul risks great dangers in the spiritual life, and even the Lord Jesus Himself does not give Himself to such a soul on a higher level, because He knows it would derive no benefit from these special graces. Second word — humility. A soul does not benefit as it should from the sacrament of confession if it is not humble. Pride keeps it in darkness. The soul neither knows how, nor is it willing, to probe with precision the depths of its own misery. It puts on a mask and avoids everything that might bring it recovery. Third word — obedience. A disobedient soul will win no victory, even if the Lord Jesus Himself, in person, were to hear its confession. The most experienced confessor will be of no help whatsoever to such a soul. The disobedient soul exposes itself to great misfortunes; it will make no progress toward perfection, nor will it succeed in the spiritual life. God lavishes His graces most generously upon the soul, but it must be an obedient soul.
377 Concerning Holy Confession. We should derive two kinds of profit from Holy Confession:
1. We come to confession to be healed;
2. We come to be educated — like a small child, our soul has constant need of education.
O my Jesus, I understand these words to their very depths, and I know from my own experience that, on its own strength, the soul will not go far; it will exert itself greatly and will do nothing for the glory of God; it will err continually, because our mind is darkened and does not know how to discern its own affairs. I shall pay special attention to two things: firstly, I will choose, in making my confession, that which humiliates me most, even if it be a trifle, but something that costs me much, and for that reason I will tell it; secondly, I will practice contrition, not only during confession, but during every self-examination, and I will arouse within myself an act of perfect contrition, especially when I am going to bed. One more word: a soul which sincerely wants to advance in perfection must observe strictly the advice given by the spiritual director. There is as much holiness as there is dependence.
1760 My daughter, I want to teach you about spiritual warfare. Never trust in yourself, but abandon yourself totally to My will. In desolation, darkness and various doubts, have recourse to Me and to your spiritual director. He will always answer you in My name. Do not bargain with any temptation; lock yourself immediately in My Heart and, at the first opportunity, reveal the temptation to the confessor. Put your self-love in the last place, so that it does not taint your deeds. Bear with yourself with great patience. Do not neglect interior mortifications. Always justify to yourself the opinions of your superiors and of your confessor. Shun murmurers like a plague. Let all act as they like; you are to act as I want you to. Observe the rule as faithfully as you can. If someone causes you trouble, think what good you can do for the person who caused you to suffer. Do not pour out your feelings. Be silent when you are rebuked. Do not ask everyone’s opinion, but only the opinion of your confessor; be as frank and simple as a child with him. Do not become discouraged by ingratitude. Do not examine with curiosity the roads down which I lead you. When boredom and discouragement beat against your heart, run away from yourself and hide in My heart. Do not fear struggle; courage itself often intimidates temptations, and they dare not attack us. Always fight with the deep conviction that I am with you. Do not be guided by feeling, because it is not always under your control; but all merit lies in the will. Always depend upon your superiors, even in the smallest things. I will not delude you with prospects of peace and consolations; on the contrary, prepare for great battles. Know that you are now on a great stage where all heaven and earth are watching you. Fight like a knight, so that I can reward you. Do not be unduly fearful, because you are not alone.
Scripture
Num 5:6-7
6 "Say to the people of Israel, When a man or woman commits any of the sins that men commit by breaking faith with the LORD, and that person is guilty,
7 he shall confess his sin which he has committed; and he shall make full restitution for his wrong, adding a fifth to it, and giving it to him to whom he did the wrong.
Prov 28:13
13 He who conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy.
John 20:21-23
21 Jesus said to them again, "Peace be with you. As the Father has sent me, even so I send you."
22 And when he had said this, he breathed on them, and said to them, "Receive the Holy Spirit.
23 If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained."
1 John 1:9
9 If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness.
Catechism of the Catholic Church
1449 The formula of absolution used in the Latin Church expresses the essential elements of this sacrament: the Father of mercies is the source of all forgiveness. He effects the reconciliation of sinners through the Passover of his Son and the gift of his Spirit, through the prayer and ministry of the Church:
God, the Father of mercies, through the death and the resurrection of his Son has reconciled the world to himself and sent the Holy Spirit among us for the forgiveness of sins; through the ministry of the Church may God give you pardon and peace, and I absolve you from your sins in the name of the Father, and of the Son, and of the Holy Spirit.
48 VII. The Acts of the Penitent
1450 “Penance requires . . . the sinner to endure all things willingly, be contrite of heart, confess with the lips, and practice complete humility and fruitful satisfaction.”49
Contrition
1458 + After that night of suffering, when the priest [Father Matzänger226] entered my cell with the Lord Jesus, such fervor filled my whole being that I felt that if the priest had tarried a little longer, Jesus himself would have leaped out of his hand and come to me.
