St. Leo the Great
400-461 AD

Saint Leo the Great (400-461 AD)

Feast Day: November 10

St. Leo I was born in Italy. He became pope in the year 440 AD, and served until 461. During his papacy, he presented a clear doctrine of Christ’s Incarnation with a letter setting down the Church’s official teaching on Jesus Christ as One Person with a human and a divine nature which could not be separated. Among the other heresies which he fought were Pelagianism, which involved denying Original Sin and failing to understand the necessity of God’s grace for salvation. He also strove to consolidate the integrity of the faith and maintain the unity of the church. His sermons and prayers have a great influence on Catholic teaching. St. Leo led Rome’s defense against Attila the Hun’s barbarian invasion in 452, by taking on the role of peacemaker. He died in 461, and he was declared doctor of the Church in 1754.


The days between the Resurrection and the Ascension of the Lord

Beloved, the days which passed between the Lord’s resurrection and his ascension were by no means uneventful; during them great sacramental mysteries were confirmed, great truths revealed. In those days the fear of death with all its horrors was taken away, and the immortality of both body and soul affirmed. It was then that the Lord breathed on all his apostles and filled them with the Holy Spirit; and after giving the keys of the kingdom to blessed Peter, whom he had chosen and set above all the others, he entrusted him with the care of his flock.

During these days the Lord joined two of his disciples as their companion on the road, and by chiding them for their timidity and hesitant fears he swept away all the clouds of our uncertainty. Their lukewarm hearts were fired by the light of faith and began to burn within them as the Lord opened up the Scriptures. And as they shared their meal with him, their eyes were opened in the breaking of bread, opened far more happily to the sight of their own glorified humanity than were the eyes of our first parents to the shame of their sin.

Throughout the whole period between the resurrection and ascension, God’s providence was at work to instill this one lesson into the hearts of the disciples, to set this one truth before their eyes, that our Lord Jesus Christ, who was truly born, truly suffered and truly died, should be recognized as truly risen from the dead. The blessed apostles together with all the others had been intimidated by the catastrophe of the cross, and their faith in the resurrection had been uncertain; but now they were so strengthened by the evident truth that when their Lord ascended into heaven, far from feeling any sadness, they were filled with great joy.

Indeed that blessed company had a great and inexpressible cause for joy when it saw man’s nature rising above the dignity of the whole heavenly creation, above the ranks of angels, above the exalted status of archangels. Nor would there be any limit to its upward course until humanity was admitted to a seat at the right hand of the eternal Father, to be enthroned at last in the glory of him to whose nature it was wedded in the person of the Son.


Contemplating the Lord’s passion

True reverence for the Lord’s passion means fixing the eyes of our heart on Jesus crucified and recognizing in him our own humanity.

The earth—our earthly nature—should tremble at the suffering of its Redeemer. The rocks—the hearts of unbelievers—should burst asunder. The dead, imprisoned in the tombs of their mortality, should come forth, the massive stones now ripped apart. Foreshadowings of the future resurrection should appear in the holy city, the Church of God: what is to happen to our bodies should now take place in our hearts.

No one, however weak, is denied a share in the victory of the cross. No one is beyond the help of the prayer of Christ. His prayer brought benefit to the multitude that raged against him. How much more does it bring to those who turn to him in repentance.

Ignorance has been destroyed, obstinacy has been overcome. The sacred blood of Christ has quenched the flaming sword that barred access to the tree of life. The age-old night of sin has given place to the true light.

The Christian people are invited to share the riches of paradise. All who have been reborn have the way open before them to return to their native land, from which they had been exiled. Unless indeed they close off for themselves the path that could be opened before the faith of a thief.

The business of this life should not preoccupy us with its anxiety and pride, so that we no longer strive with all the love of our heart to be like our Redeemer, and to follow his example. Everything that he did or suffered was for our salvation: he wanted his body to share the goodness of its head.

First of all, in taking our human nature while remaining God, so that the Word became man, he left no member of the human race, the unbeliever excepted, without a share in his mercy. Who does not share a common nature with Christ if he has welcomed Christ, who took our nature, and is reborn in the Spirit through whom Christ was conceived?

Again, who cannot recognize in Christ his own infirmities? Who would not recognize that Christ’s eating and sleeping, his sadness and his shedding of tears of love are marks of the nature of a slave?

It was this nature of a slave that had to be healed of its ancient wounds and cleansed of the defilement of sin. For that reason the only-begotten Son of God became also the son of man. He was to have both the reality of a human nature and the fullness of the godhead.

The body that lay lifeless in the tomb is ours. The body that rose again on the third day is ours. The body that ascended above all the heights of heaven to the right hand of the Father’s glory is ours. If then we walk in the way of his commandments, and are not ashamed to acknowledge the price he paid for our salvation in a lowly body, we too are to rise to share his glory. The promise he made will be fulfilled in the sight of all: Whoever acknowledges me before men, I too will acknowledge him before my Father who is in heaven.


Purification of spirit through fasting and almsgiving

Dear friends, at every moment the earth is full of the mercy of God, and nature itself is a lesson for all the faithful in the worship of God. The heavens, the sea and all that is in them bear witness to the goodness and omnipotence of their Creator, and the marvelous beauty of the elements as they obey him demands from the intelligent creation a fitting expression of its gratitude.

But with the return of that season marked out in a special way by the mystery of our redemption, and of the days that lead up to the paschal feast, we are summoned more urgently to prepare ourselves by a purification of spirit.

The special note of the paschal feast is this: the whole Church rejoices in the forgiveness of sins. It rejoices in the forgiveness not only of those who are then reborn in holy baptism but also of those who are already numbered among God’s adopted children.

Initially, men are made new by the rebirth of baptism. Yet there still is required a daily renewal to repair the shortcomings of our mortal nature, and whatever degree of progress has been made there is no one who should not be more advanced. All must therefore strive to ensure that on the day of redemption no one may be found in the sins of his former life.

Dear friends, what the Christian should be doing at all times should be done now with greater care and devotion, so that the Lenten fast enjoined by the apostles may be fulfilled, not simply by abstinence from food but above all by the renunciation of sin.

There is no more profitable practice as a companion to holy and spiritual fasting than that of almsgiving. This embraces under the single name of mercy many excellent works of devotion, so that the good intentions of all the faithful may be of equal value, even where their means are not. The love that we owe both God and man is always free from any obstacle that would prevent us from having a good intention. The angels sang: Glory to God in the highest, and peace to his people on earth. The person who shows love and compassion to those in any kind of affliction is blessed, not only with the virtue of good will but also with the gift of peace.

The works of mercy are innumerable. Their very variety brings this advantage to those who are true Christians, that in the matter of almsgiving not only the rich and affluent but also those of average means and the poor are able to play their part. Those who are unequal in their capacity to give can be equal in the love within their hearts.


Christ lives in his Church

My dear brethren, there is no doubt that the Son of God took our human nature into so close a union with himself that one and the same Christ is present, not only in the firstborn of all creation, but in all his saints as well. The head cannot be separated from the members, nor the members from the head. Not in this life, it is true, but only in eternity will God be all in all, yet even now he dwells, whole and undivided, in his temple the Church. Such was his promise to us when he said: See, I am with you always, even to the end of the world.

And so all that the Son of God did and taught for the world’s reconciliation is not for us simply a matter of past history. Here and now we experience his power at work among us. Born of a virgin mother by the action of the Holy Spirit, Christ keeps his Church spotless and makes her fruitful by the inspiration of the same Spirit. In baptismal regeneration she brings forth children for God beyond all numbering. These are the sons of whom it is written: They are born not of blood, nor of the desire of the flesh, nor of the will of man, but of God.

In Christ Abraham’s posterity is blessed, because in him the whole world receives the adoption of sons, and in him the patriarch becomes the father of all nations through the birth, not from human stock but by faith, of the descendants that were promised to him. From every nation on earth, without exception, Christ forms a single flock of those he has sanctified, daily fulfilling the promise he once made: I have other sheep, not of this fold, whom it is also ordained that I shall lead; and there shall be one flock and one shepherd.

Although it was primarily to Peter that he said: Feed my sheep, yet the one Lord guides all the pastors in the discharge of their office and leads to rich and fertile pastures all those who come to the rock. There is no counting the sheep who are nourished with his abundant love, and who are prepared to lay down their lives for the sake of the good shepherd who died for them.

But it is not only the martyrs who share in his passion by their glorious courage; the same is true, by faith, of all who are reborn through baptism. That is why we are to celebrate the Lord’s paschal sacrifice with the unleavened bread of sincerity and truth. The leaven of our former malice is thrown out, and a new creature is filled and inebriated with the Lord himself. For the effect of our sharing in the body and blood of Christ is to change us into what we receive. As we have died with him, and have been buried and raised to life with him, so we bear him within us, both in body and in spirit, in everything we do.


The mystery of our reconciliation with God

To speak of our Lord, the son of the Blessed Virgin Mary, as true and perfect man is of no value to us if we do not believe that he is descended from the line of ancestors set out in the Gospel. Matthew’s gospel begins by setting out the genealogy of Jesus Christ, son of David, son of Abraham, and then traces his human descent by bringing his ancestral line down to his mother’s husband, Joseph. On the other hand, Luke traces his parentage backward step by step to the actual father of mankind, to show that both the first and the last Adam share the same nature.

No doubt the Son of God in his omnipotence could have taught and sanctified men by appearing to them in a semblance of human form as he did to the patriarchs and prophets, when for instance he engaged in a wrestling contest or entered into conversation with them, or when he accepted their hospitality and even ate the food they set before him. But these appearances were only types, signs that mysteriously foretold the coming of one who would take a true human nature from the stock of the patriarchs who had gone before him. No mere figure, then, fulfilled the mystery of our reconciliation with God, ordained from all eternity. The Holy Spirit had not yet come upon the Virgin nor had the power of the Most High overshadowed her, so that within her spotless womb Wisdom might build itself a house and the Word become flesh. The divine nature and the nature of a servant were to be united in one person so that the Creator of time might be born in time, and he through whom all things were made might be brought forth in their midst.

For unless the new man, by being made in the likeness of sinful flesh, had taken on himself the nature of our first parents, unless he had stooped to be one in substance with his mother while sharing the Father’s substance and, being alone free from sin, united our nature to his, the whole human race would still be held captive under the dominion of Satan. The Conqueror’s victory would have profited us nothing if the battle had been fought outside our human condition. But through this wonderful blending the mystery of new birth shone upon us, so that through the same Spirit by whom Christ was conceived and brought forth we too might be born again in a spiritual birth; and in consequence the evangelist declares the faithful to have been born not of blood, nor of the desire of the flesh, nor of the will of man, but of God.


The Cross of Christ is the source of all blessings, the cause of all graces

Our understanding, which is enlightened by the Spirit of truth, should receive with purity and freedom of heart the glory of the cross as it shines in heaven and on earth. It should see with inner vision the meaning of the Lord’s words when he spoke of the imminence of his passion: The hour has come for the Son of Man to be glorified. Afterward he said: Now my soul is troubled, and what am I to say? Father, save me from this hour. But it was for this that I came to this hour. Father, glorify your Son. When the voice of the Father came from heaven, saying, I have glorified him, and will glorify him again, Jesus said in reply to those around him: It was not for me that this voice spoke, but for you. Now is the judgment of the world, now will the prince of this world be cast out. And I, if I am lifted up from the earth, will draw all things to myself.

How marvelous the power of the cross; how great beyond all telling the glory of the passion: here is the judgment-seat of the Lord, the condemnation of the world, the supremacy of Christ crucified.

Lord, you drew all things to yourself so that the devotion of all peoples everywhere might celebrate, in a sacrament made perfect and visible, what was carried out in the one temple of Judea under obscure foreshadowings.

Now there is a more distinguished order of Levites, a greater dignity for the rank of elders, a more sacred anointing for the priesthood, because your cross is the source of all blessings, the cause of all graces. Through the cross the faithful receive strength from weakness, glory from dishonor, life from death.

The different sacrifices of animals are no more: the one offering of your body and blood is the fulfillment of all the different sacrificial offerings, for you are the true Lamb of God: you take away the sins of the world. In yourself you bring to perfection all mysteries, so that, as there is one sacrifice in place of all other sacrificial offerings, there is also one kingdom gathered from all peoples.

Dearly beloved, let us then acknowledge what Saint Paul, the teacher of the nations, acknowledged so exultantly: This is a saying worthy of trust, worthy of complete acceptance: Christ Jesus came into this world to save sinners.

God’s compassion for us is all the more wonderful because Christ died, not for the righteous or the holy but for the wicked and the sinful, and, though the divine nature could not be touched by the sting of death, he took to himself, through his birth as one of us, something he could offer on our behalf.

The power of his death once confronted our death. In the words of Hosea the prophet: Death, I shall be your death; grave, I shall swallow you up. By dying he submitted to the laws of the underworld; by rising again he destroyed them. He did away with the everlasting character of death so as to make death a thing of time, not of eternity. As all die in Adam, so all will be brought to life in Christ.
