I think it is correct, if not the most clear and precise. Here are some examples of those things being said to forgive sins in the Church:
[quote=prayer of priest or deacon at Mass]Through the words of the Gospel may our sins be wiped away.
[quote=CCC]1434 The interior penance of the Christian can be expressed in many and various ways. Scripture and the Fathers insist above all on three forms, fasting, prayer, and almsgiving,31 which express conversion in relation to oneself, to God, and to others. Alongside the radical purification brought about by Baptism or martyrdom they cite as means of obtaining forgiveness of sins: effort at reconciliation with one’s neighbor, tears of repentance, concern for the salvation of one’s neighbor, the intercession of the saints, and the practice of charity "which covers a multitude of sins."32
[quote=Pope Benedict XVI]What is more: Saint Peter includes among the spiritual fruits of almsgiving the forgiveness of sins: “Charity,” he writes, “covers a multitude of sins” (1 Pt 4,8).
[quote=St. Augustine]71. For the passing and trivial sins of every day, from which no life is free, the everyday prayer of the faithful makes satisfaction. For they can say, “Our Father who art in heaven,” who have already been reborn to such a Father "by water and the Spirit."155 This prayer completely blots out our minor and everyday sins. It also blots out those sins which once made the life of the faithful wicked, but from which, now that they have changed for the better by repentance, they have departed. The condition of this is that just as they truly say, “Forgive us our debts” (since there is no lack of debts to be forgiven), so also they truly say, "As we forgive our debtors"156; that is, if what is said is also done. For to forgive a man who seeks forgiveness is indeed to give alms.
- Accordingly, what our Lord says—"Give alms and, behold, all things are clean to you"157—applies to all useful acts of mercy. Therefore, not only the man who gives food to the hungry, drink to the thirsty, clothing to the naked, hospitality to the wayfarer, refuge to the fugitive; who visits the sick and the prisoner, redeems the captive, bears the burdens of the weak, leads the blind, comforts the sorrowful, heals the sick, shows the errant the right way, gives advice to the perplexed, and does whatever is needful for the needy158—not only does this man give alms, but the man who forgives the trespasser also gives alms as well. He is also a giver of alms who, by blows or other discipline, corrects and restrains those under his command, if at the same time he forgives from the heart the sin by which he has been wronged or offended, or prays that it be forgiven the offender. Such a man gives alms, not only in that he forgives and prays, but also in that he rebukes and administers corrective punishment, since in this he shows mercy.
