Catechism of the Council of Trent: "Forgive our trespasses as we forgive those who trespass against us"
The Fifth Petition of the Lord's Prayer: " and Forgive Us Our Debts, as We Forgive Our Debtors"
The Importance Of Explaining This Petition
So many are the things which display at once God's infinite power and His equally infinite wisdom and goodness, that wheresoever we turn our eyes or direct our thoughts, we meet with the most certain signs of omnipotence and benignity. And yet there is truly nothing that more eloquently proclaims His supreme love and admirable charity towards us, than the inexplicable mystery of the Passion of Jesus Christ, whence springs that never-failing fountain to wash away the defilements of sin. (It is this fountain) in which, under the guidance and bounty of God, we desire to be merged and purified, when we beg of Him to forgive us our debts.
This Petition contains a sort of summary of those benefits with which the human race has been enriched through Jesus Christ. This Isaias taught when he said: The iniquity of the house of Jacob shall be forgiven; and this is all the fruit, that the sin thereof should be taken away. David also shows this, proclaiming those blessed who could partake of that salutary fruit: Blessed are they whose iniquities are forgiven.
The pastor, therefore, should study and explain accurately and diligently the meaning of this Petition, which, we perceive, is so important to the attainment of salvation.
Difference Between This And The Preceding Petitions
In this Petition we enter on a new manner of praying. For hitherto we asked of God not only eternal and spiritual goods, but also transient and temporal advantages; whereas, we now ask to be freed from the evils of the soul and of the body, of this life and of the life to come.
Dispositions with which this petition should be Offered
Since, however, to obtain what we ask we must pray in a becoming manner, it appears expedient to explain the disposition with which this prayer should be offered to God.
Acknowledgment Of Sin
The pastor, then, should admonish the faithful, that he who comes to offer this Petition must first acknowledge, and next feel sorrow and compunction for his sins. He must also be firmly convinced that to sinners, thus disposed and prepared, God is willing to grant pardon. This confidence is necessary to sinners, lest perhaps the bitter remembrance and acknowledgment of their sins should be followed by that despair of pardon, which of old seized the mind of Cain and of Judas, both of whom looked on God solely as an avenger and punisher, forgetting that He is also mild and merciful.
In this Petition, therefore, we ought to be so disposed, that, acknowledging our sins in the bitterness of our souls, we may fly to God as to a Father, not as to a Judge, imploring Him to deal with us not according to His justice, but according to His mercy.
We shall be easily induced to acknowledge our sins if we listen to God Himself admonishing us through the Sacred Scriptures in this regard. Thus we read in David: They are all gone aside; they are become unprofitable together; there is none that doeth good, no not one. Solomon speaks to the same purpose: There is no just man upon earth, that doth good, and sinneth not. To this subject apply also these words: Who can say: "my heart is clean, I am pure from sin?" The very same has been written by St. John to deter men from arrogance: If we say that we have no sin, we deceive ourselves, and the truth is not in us. Jeremias also says: Thou hast said: "I am without sin, and am innocent"; and therefore, let thy anger be turned away from me. Behold, I will contend with thee in judgment, because thou hast said: "I have not sinned."
Christ the Lord, who spoke by the mouth of all these, confirms their teaching by this Petition in which He commands us to confess our sins. The Council of Milevi forbids us to interpret it otherwise. It hath pleased the Council, that whosoever will have it that these words of the Lord's prayer, "forgive us our debts," are said by holy men in humility, not in truth, let him be anathema. For who can endure a person praying, and lying not to men, but to the Lord Himself, saying with the lips that he desires to be forgiven, but with the heart, that he has no debts to be forgiven ?
Sorrow For Sin
In making this necessary acknowledgment of our sins, it is not enough to call them to mind lightly; for it is necessary that the recollection of them be bitter, that it touch the heart, pierce the soul, and imprint sorrow. Wherefore, the pastor should treat this point diligently, that his pious hearers may not only recollect their sins, and iniquities, but recollect them with pain and sorrow; so that with true interior contrition they may betake themselves to God their Father, humbly imploring Him to pluck from the soul the piercing stings of sin.
Motives For Sorrow Over Sin: The Baseness Of Sin
The pastor, however, should not be content with placing before the eyes of the faithful the turpitude of sin. He should also depict the unworthiness and baseness of men, who, though nothing but rottenness and corruption, dare to outrage in a manner beyond all belief the incomprehensible majesty and ineffable excellence of God, particularly after having been created, redeemed and enriched by Him with countless and invaluable benefits.
The Consequences Of Sin
And for what? Only for this, that separating ourselves from God our Father, who is the supreme Good, and lured by the most base rewards of sin, we may devote ourselves to the devil, to become his most wretched slaves. Language is inadequate to depict the cruel tyranny which the devil exercises over those who, having shaken off the sweet yoke of God, and broken the most lovely bond of charity by which our spirit is bound to God our Father, have gone over to their relentless enemy, who is therefore called in Scripture, the prince and ruler of the world, the prince of darkness, and king over all the children of pride. Truly to those who are oppressed by the tyranny of the devil apply these words of Isaias: O Lord our God, other lords besides thee have had dominion over us.
If these broken covenants of love do not move us, let at least the calamities into which we fall by sin move us. The sanctity of the soul is violated, which we know to have been wedded to Christ. That temple of the Lord is profaned, against the contaminators of which the Apostle utters this denunciation: If any man violate the temple of God, him shall God destroy.
Innumerable are the evils brought upon man by sin, that almost infinite pest of which David says: There is no health in my flesh, because of thy wrath; there is no peace for my bones, because of my sins. In these words he marks the violence of the plague, confessing that it left no part of him uninfected by pestiferous sin; for the poison had penetrated into his bones, that is, it infected his understanding and will, which are the two most intimate faculties of the soul. This widespread pestilence the Sacred Scriptures point out, when they designate sinners as the lame, the deaf, the dumb, the blind, the paralysed.
But, besides the anguish which he felt on account of the enormity of his sins, David was afflicted yet more by the knowledge that he had provoked the wrath of God against him by his sin. For the wicked are at war with God, who is offended beyond belief at their crimes; hence the Apostle says: Wrath and indignation, tribulation and anguish upon every soul of man that worketh evil. Although the sinful act is transient, yet the sin by its guilt and stain remains; and the imminent wrath of God pursues it, as the shadow does the body.
When, therefore, David was pierced by these tormenting thoughts, he was moved to seek the pardon of his sins. That the faithful, imitating the Prophet, may learn to grieve, that is, to become truly penitent, and cherish the hope of pardon, the pastor should call to their attention the example of David's penitential sorrow, and the lessons of instruction drawn from his fiftieth Psalm.
How great is the utility of this sort of instruction, which teaches us to grieve for our sins, God Himself declares by the mouth of Jeremias, who, when exhorting the Israelites to repentance, admonished them to awake to a sense of the evils that follow upon sin. See, he says, that it is an evil and a bitter thing for thee, to have left the Lord thy God, and that my fear is not with thee, saith the Lord, the God of hosts. They who lack this necessary sense of acknowledgment and grief, are said by the Prophets Isaias, Ezechiel and Zachary to have a hard heart, a stony heart, a heart of adamant, for, like stone, they are softened by no sorrow, having no sense of life, that is, of the salutary recognition (of their sinfulness).
