Commemoratio: S. Lucæ Evangelistæ
“Put ye on the armour of God, that you may be able to stand against the deceits of the devil.” — Ephesians 6:11 (Douay-Rheims)
On this Twenty-First Sunday after Pentecost, the Holy Church presents us with a profound and sobering juxtaposition. The Epistle calls us to the vigilance of the soldier, urging us to don the “whole armour of God” to withstand the fiery darts of the wicked one. Yet, the Gospel of the day offers a parable of startling severity regarding the unforgiving servant, illustrating the terrifying reality of a soul that has received infinite mercy yet refuses to extend it to its neighbor.
In the spirit of the Second Classis feast of this Sunday, and in commemoration of Saint Luke the Evangelist, whose gentle pen recorded so many of Christ’s parables on mercy, we are invited to reflect on the inseparable bond between spiritual warfare and charity. How can one stand firm against the devil if one harbors an unforgiving heart? And how can we truly wear the breastplate of justice if we deny the mercy we have ourselves received?
The Liturgical Context: Vigilance and Judgment
The Mass of this day, classified as II classis, emphasizes the gravity of the spiritual battle. The Introit, taken from Psalm 26, cries out: “The Lord is my light and my salvation; whom shall I fear?” It is a prayer of confidence, yet it presupposes the existence of enemies—”the evil doers”—who are at hand to devour.
The Epistle reading, Ephesians 6:10-17, is the classic text of Christian militarism. St. Paul, writing from prison, does not speak of physical combat but of a cosmic struggle. “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 high places” (Eph 6:12).
The Gospel, Matthew 18:23-35, the Parable of the Unforgiving Servant, serves as the practical application of this warfare. The King (Christ) forgives a servant a debt of ten thousand talents—a sum impossible to repay. This servant, however, immediately encounters a fellow servant who owes him a hundred pence. He refuses mercy, has his friend cast into prison, and is subsequently handed over to the tormentors by the King who had forgiven him.
The Church Fathers saw in this parable not merely a lesson on forgiveness, but a revelation of the mechanics of the soul’s defense. To refuse forgiveness is to disarm oneself of the very armor required to stand against the devil.
The Armour of God: A Shield Against the Spirit of Wrath
St. Paul enumerates the pieces of this divine armor: the girdle of truth, the breastplate of justice, the shoes of the gospel of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit.
St. John Chrysostom, in his homilies on Ephesians, marvels at the completeness of this equipment. He notes that the Apostle does not say, “put on the sword,” but “the sword of the Spirit, which is the word of God.” Yet, he warns that without the other virtues, the sword is useless. Specifically, Chrysostom connects the “shoes of the gospel of peace” with the readiness to forgive. One cannot walk the path of peace while holding a grudge. The unforgiving heart is heavy with the lead of resentment, making the soldier slow and vulnerable to the enemy’s attacks.
The breastplate of justice (justitia) protects the heart. But what is true justice? As St. Augustine teaches in his sermons on the Psalms, true justice includes mercy. A man who demands his rights while ignoring the debts of others is not just; he is unjust. By refusing to forgive the “hundred pence” owed by our neighbor, we violate the justice of the King who forgave us the “ten thousand talents.” Thus, the breach in our armor is often found in our refusal to show mercy.
The Unforgiving Heart as an Open Wound
The Gospel reveals the tragic irony of the servant who was forgiven. He did not lose his forgiveness because he failed to pay the debt; he lost it because he failed to imitate the nature of his Master.
St. Gregory the Great, in his Moralia in Job and various homilies, expounds on this dynamic. He argues that the devil finds his greatest foothold not in our initial sins, but in our subsequent pride and lack of charity. When we refuse to forgive, we effectively tell God, “Your mercy is sufficient for me, but it is too much for my neighbor.” This is a rebellion against the order of grace.
The “tormentors” (exactoribus) to whom the unforgiving servant is delivered are interpreted by the Fathers as the demons themselves. St. Cyril of Alexandria remarks that the devil is the accuser and the tormentor of souls. When we withhold forgiveness, we invite the devil to become our tormentor, for we have placed ourselves outside the protection of the King’s mercy. The debt we owe to God is so vast that we could never repay it; the debt our neighbor owes us is trivial by comparison. To be cast into prison for the latter, having been freed for the former, is the ultimate tragedy of the spiritual life.
Saint Luke: The Physician of Souls
In commemorating Saint Luke the Evangelist, we find a special resonance with this theme. Luke, the beloved physician (Col 4:14), is traditionally seen as the evangelist of mercy. He alone records the Parable of the Prodigal Son and the Good Samaritan. His Gospel is filled with Christ’s concern for the sick, the poor, and the sinner.
The Church pairs the military exhortation of St. Paul with the memory of St. Luke to remind us that the warfare of the Christian is not one of cruelty, but of healing. The “sword of the Spirit” cuts away sin, but it is wielded with the hands of a physician. To fight the devil, we must be like Luke: attentive to the wounds of others, ready to apply the balm of forgiveness.
As St. Thomas Aquinas notes in his commentary on the Epistles, the virtue of charity is the form of all virtues. Without charity, even the act of fighting the devil becomes a source of condemnation. The soldier who fights with hatred in his heart is already defeated.
Practical Application: Donning the Armour Daily
How, then, do we apply this teaching in our daily lives?
- Examine the Heart: Before entering into prayer or the Mass, we must ask ourselves: Is there anyone I am refusing to forgive? Is there a small grievance, a slight, or a debt that I am clinging to? If so, we are approaching the altar without the “shoes of peace.”
- Imitate the King: When we recall the magnitude of our own sins—the “ten thousand talents”—we must realize that any offense committed against us is negligible. The forgiveness we seek from God is conditional upon our willingness to forgive others, as the Lord taught in the Our Father: “Forgive us our trespasses, as we forgive those who trespass against us.”
- Active Charity: Forgiveness is not merely a passive feeling; it is an active virtue. We must pray for those who have wronged us. We must seek their good. This is the “gospel of peace” in action.
- The Shield of Faith: When the devil tempts us to bitterness, we must raise the shield of faith, remembering that God’s judgment is perfect and that we are saved only by grace, not by our own merit.
Conclusion
The Twenty-First Sunday after Pentecost calls us to a serious examination of conscience. The devil is real, and his assaults are fierce. But the most effective weapon against him is not our own strength, but the grace of God received through a heart open to mercy.
As St. Augustine famously prayed: “Grant, O Lord, what Thou commandest, and command what Thou desirest.” Grant us the courage to put on the whole armour of God, and the humility to forgive as we have been forgiven. For if we do not forgive men their trespasses, neither will our Heavenly Father forgive us ours.
Let us conclude with the Collect of the day, praying for the grace to stand firm:
O God, who dost manifest Thy almighty power chiefly in pardoning and showing mercy: mercifully grant unto us such a measure of Thy grace, that we may run the way of Thy commandments, and obtain Thy promises, which Thou hast prepared for them that love Thee. Through Christ our Lord. Amen.
May the intercession of Saint Luke the Evangelist and the example of the Saints guide us in this spiritual warfare, that we may stand victorious in the day of trial.
