A Reflection for Feria Quarta infra Hebdomadam XXI post Octavam Pentecostes IV. Octobris ~ IV. classis
Introduction
On this fourth-class ferial day, Holy Mother Church sets before her children two readings which at first glance seem to speak of different worlds: the Apostle Paul arming the Christian for spiritual combat, and our Lord Jesus Christ pronouncing judgment upon an unforgiving servant. Yet the liturgy, in her ancient wisdom, joins them in a single lesson. For the man who refuses to forgive his brother has already laid down the armour of God; he stands naked upon the battlefield, and the enemy has found him.
The Epistle appointed for this day (Eph 6:10-17) opens with the trumpet blast: “Finally, brethren, be strengthened in the Lord, and in the power of his might.” The Gospel (Matt 18:23-35) closes with the warning of the king who delivered the unforgiving servant “to the torturers, until he should pay all that was due him.” Between the arming and the accounting lies the whole drama of the Christian soul.
Let us consider, then, what the Fathers teach us concerning this warfare, and what the parable reveals about the one weapon we are most tempted to cast aside.
Liturgical Context
This ferial day falls within the twenty-first week after the Octave of Pentecost, in the season of the Tempus per Annum — the time in which the Church, having received the Holy Ghost at Pentecost, labours in the world He came to sanctify. The Mass is of the IV. classis, a ferial day without proper festal rank, yet possessing its own appointed propers drawn from the preceding Sunday, the Twenty-First after Pentecost.
The Introit echoes the cry of the soul besieged: In te, Domine, speravi — “In thee, O Lord, have I hoped” (Ps 118:1). The Collect begs of God that His mercy may “cleanse and defend” His family, that we may be “continually defended from all adversities.” Note well the order: cleanse first, then defend. The armour cannot be worn over uncleanness; the soldier must be washed before he is armed.
The Epistle, as noted, is St. Paul’s summons to the panoplia — the full armour of God. The Gospel is our Lord’s parable of the unforgiving servant, spoken in answer to Peter’s question, “How often shall my brother offend against me, and I forgive him? till seven times?” (Matt 18:21).
The Gradual and Alleluia verses speak of the Lord as refuge and deliverer, preparing the soul to receive the Gospel’s hard word concerning mercy and its refusal.
Doctrinal Reflection
I. The Nature of the Warfare: Not Against Flesh and Blood
St. Paul is emphatic: “For our wrestling is not against flesh and blood; but against principalities and powers, against the rulers of the world of this darkness, against the spirits of wickedness in the high places” (Eph 6:12).
St. John Chrysostom, commenting on this passage in his Homilies on Ephesians, observes that the Apostle does not merely warn of enemies, but describes their ranks and hierarchy — principalities, powers, rulers of the world of this darkness — precisely so that the believer may understand the gravity of the contest and not presume upon his own strength. “He shows us the battle array of the adversary,” writes Chrysostom, “that we may know against whom we fight, and how we must be armed.” The warfare is invisible; the weapons must therefore be spiritual.
St. Jerome, in his commentary on this Epistle, notes that the “armour of God” is not our own invention but God’s gift. We do not forge it; we receive it. This is the first lesson of humility: the soldier who trusts in his own arm is already defeated.
II. The Seven Pieces of the Panoply
The Apostle enumerates: the girdle of truth, the breastplate of justice, the shoes of the Gospel of peace, the shield of faith, the helmet of salvation, the sword of the Spirit (which is the word of God), and — added at verse 18 — “praying at all times with all manner of prayer and supplication in the Spirit.”
St. Thomas Aquinas, in his treatment of this passage, draws out the moral sense: truth girds the loins because the generative faculty must be restrained by truth; justice guards the heart because the irascible appetite must be ordered; the Gospel of peace shod upon the feet because the affections must be prepared for the way of charity. Each piece corresponds to a faculty of the soul, and each must be worn if the whole man is to stand.
St. Augustine, in the De Doctrina Christiana, reminds us that the sword of the Spirit is the word of God — not our own cleverness, not human eloquence, but the Scriptures understood in the mind of the Church. The soldier who wields his own opinions in place of the divine word has drawn a wooden sword against steel.
III. The Unforgiving Servant: Where the Armour Falls
Now consider the Gospel. A servant owes his lord ten thousand talents — an impossible sum, representing the infinite debt of sin against God. He falls down and begs for patience. The lord, moved with compassion, forgives him the entire debt.
Yet the same servant, going out, seizes a fellow servant who owes him a hundred pence — a trifling amount by comparison — and casts him into prison. When the lord hears of it, he revokes his pardon: “Shouldst not thou also have had compassion on thy fellow servant, even as I had pity on thee?” And he delivers him to the torturers.
Here is the terrifying truth: the man who refuses to forgive has forfeited the forgiveness he received. He has taken off the breastplate of justice, which is mercy rendered to others; he has dropped the shield of faith, for faith without works of charity is dead (James 2:26); he has abandoned the Gospel of peace, whose very name is reconciliation.
St. John Chrysostom, preaching on this parable, exclaims: “Nothing so provokes God as the remembrance of injuries and the refusal to forgive. For this cause He hath given us a prayer, that we should say, ‘Forgive us our debts, as we also forgive our debtors.’ If we do not forgive, we pray against ourselves.” The Pater Noster itself becomes a sword turned against the unforgiving heart.
St. Augustine, in his Sermon 83, teaches that the hundred pence represent all offenses committed against us by our neighbour, while the ten thousand talents represent the debt we owe to God. “What is a hundred pence compared to ten thousand talents? And yet the servant would not forgive the lesser, after being forgiven the greater.” The disproportion is the whole point: our sins against God are immeasurably greater than any wrong done to us by another.
IV. The Catechism of Trent on the Forgiveness of Injuries
The Catechism of the Council of Trent, in its exposition of the Lord’s Prayer, treats the petition “Forgive us our trespasses” with great solemnity. It teaches that this petition is unique among the seven, for in it we do not merely ask a favour — we enter into a covenant. “We beseech God,” says the Catechism, “to grant us that remission of sins which we ourselves grant to those who have injured us.” The condition is explicit in the words our Lord Himself gave us: as we forgive.
The Catechism further warns that the man who prays this petition while harbouring unforgiveness “does not pray, but rather imprecates a curse upon himself.” For he asks God to forgive him in the measure in which he forgives others — and if that measure is zero, he asks for nothing.
This is the doctrinal heart of the matter: the forgiveness of injuries is not merely a counsel of perfection, nor a pious sentiment, but a condition of salvation. It is woven into the very fabric of the prayer Christ taught us.
V. The Council of Trent on Penance and Satisfaction
The Council of Trent, in its Doctrine on the Sacrament of Penance (Session XIV), teaches that contrition, confession, and satisfaction are the acts of the penitent, and that absolution removes the eternal punishment due to sin. Yet the Council also teaches that temporal punishment may remain, to be expiated in this life or in Purgatory. The unforgiving servant, delivered to the torturers, is a figure of the soul that receives pardon but refuses to render the satisfaction of charity. As St. Gregory the Great writes in his Homilies on the Gospels, “The torturers are the ministers of vengeance; and he is delivered to them who, having been forgiven, would not forgive.”
Practical Application
What, then, shall the faithful soul do on this ferial day?
First, examine the conscience regarding unforgiveness. Is there a person against whom resentment is harboured — a family member, a colleague, a fellow parishioner? The armour of God cannot be worn over such a wound. Let the soul kneel before the Crucifix and say with St. Stephen, “Lord, lay not this sin to their charge” (Acts 7:60).
Second, approach the Sacrament of Penance with true contrition. The Council of Trent insists that confession be integral and contrition supernatural, springing from love of God rather than mere fear of punishment. The grace of absolution restores the soul to friendship with God — but the soul must then extend that same mercy outward.
Third, cultivate the habit of intercessory prayer for those who have injured us. St. Augustine advises that when we find it hard to forgive, we should pray for the offender by name, asking God to bless him. “It is impossible,” he writes, “to continue in hatred toward one for whom you pray.”
Fourth, meditate upon the Passion of Christ. He who bore the ten thousand talents of our debt prayed for His executioners: “Father, forgive them, for they know not what they do” (Luke 23:34). The soldier who gazes upon the Cross learns the cost of his own pardon — and the price of withholding it from another.
Fifth, let the faithful make frequent use of the Confiteor and the Pater Noster, not rushing over the words but weighing them. The petition dimitte nobis debita nostra is either the sweetest consolation or the most terrible indictment, depending on the state of the heart.
Conclusion
The Apostle arms us for war; our Lord warns us of the accounting. The two cannot be separated. The whole armour of God is worn by the man who knows he has been forgiven much — and who therefore forgives much. The unforgiving servant was not defeated by the principalities and powers; he was undone by his own refusal to show mercy. He had the form of a servant, but not the heart of one.
Let us, then, on this ferial day, put on the girdle of truth, which admits our own debt; the breastplate of justice, which renders to each what is due; the shoes of the Gospel of peace, which carries reconciliation wherever we walk; the shield of faith, which quenches the fiery darts of resentment; the helmet of salvation, which guards the mind from brooding upon injuries; and the sword of the Spirit, which cuts through the knot of bitterness with the word of God. And above all, let us pray at all times in the Spirit, saying with the Church:
Pater noster, qui es in caelis… dimitte nobis debita nostra, sicut et nos dimittimus debitoribus nostris.
So may the King, when He comes to reckon with His servants, find us not among the torturers, but among the merciful — who shall obtain mercy (Matt 5:7).
