Leo the Great — Commentary on Scripture

John 20:29

It is the strength of great minds and the light of firmly faithful souls unhesitatingly to believe what is not seen with the bodily sight and to focus your affections where you cannot direct your gaze. And from where should this godliness spring up in our hearts or how should someone be justified by faith, if our salvation rested on those things only that lie beneath our eyes? And so, our Lord said to Thomas, who seemed to doubt Christ’s resurrection until he had tested by sight and touched the traces of his passion in his very flesh, “because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”

SERMON 74.1

Leviticus 11:44

He himself says, “Be holy, for I am holy,” that is to say, choose me and keep away from what displeases me. Do what I love; love what I do. If what I order seems difficult, come back to me who ordered it, so that from where the command was given help might be offered. I who furnished the desire will not refuse support. Fast from contradiction, abstain from opposition. Let me be your food and drink. None desire in vain what is mine, for those who stretch out toward me seek me because I first sought them.

SERMON 94.2

Luke 1:34-35

But the birth of our Lord Jesus Christ exceeds all understanding and goes beyond any precedent.

SERMON 30.4.2

Luke 1:34-35

Each one is a partaker of this spiritual origin in regeneration. To every one, when he is reborn, the water of baptism is like the Virgin’s womb, for the same Holy Spirit fills the font, who filled the Virgin, that the sin, which that sacred conception overthrew, may be taken away by this mystical washing.

SERMON 24.3

Luke 1:34

In this nativity also, Isaiah's saying is fulfilled, "let the earth produce and bring forth salvation, and let righteousness spring up together." [Isaiah 45:8] For the earth of human flesh, which in the first transgressor, was cursed, in this Offspring of the Blessed Virgin only produced a seed that was blessed and free from the fault of its stock. And each one is a partaker of this spiritual origin in regeneration; and to every one when he is re-born, the water of baptism is like the Virgin's womb; for the same Holy Spirit fills the font, Who filled the Virgin, that the sin, which that sacred conception overthrew, may be taken away by this mystical washing.

Sermon 24, Section III

Luke 12:16-20

The devil, even in the midst of our efforts, does not relax his schemes. At certain periods of time, we must take care of the reenergizing of our strength. The mind, concerned with the goods of the present, can rejoice in the temperate weather and the fertile fields. When the fruits are gathered into great barns, it can say to its soul, “You have many good things; eat.” It may receive a kind of rebuke from the divine voice and may hear it saying, “Fool, this very night they demand your soul from you. The things you have prepared, whose will they be?”This should be the careful consideration of wise people, that since the days of this life are short and the time uncertain, death should never be unexpected for those who are to die. Those who know that they are mortal should not come to an unprepared end.

SERMON 90.4.1

Luke 21:1-4

Although the spite of some people does not grow gentle with any kindness, nevertheless the works of mercy are not fruitless, and kindness never loses what is offered to the ungrateful. May no one, dearly beloved, make themselves strangers to good works. Let no one claim that his poverty scarcely sufficed for himself and could not help another. What is offered from a little is great, and in the scale of divine justice, the quantity of gifts is not measured but the steadfastness of souls. The “widow” in the Gospel put two coins into the “treasury,” and this surpassed the gifts of all the rich. No mercy is worthless before God. No compassion is fruitless. He has given different resources to human beings, but he does not ask different affections.

SERMON 20.3.1

Luke 22:61

Then “the Lord looked at Peter.” Christ stood in the middle of the priests’ insults, the witnesses’ lies, and the injuries of those that struck him and spat on him. He met the troubled disciple with his eyes, the same eyes that had foreseen that Peter would undergo a struggle. In so doing, the gaze of truth entered Peter, directed toward the place where the amendment of his heart would be grounded. It was as if the Lord’s voice were echoing within Peter, saying, “What are you thinking, Peter? Why do you withdraw into yourself? Turn to me, trust in me”, and “follow me.” This is the time for my passion. The hour of your suffering has not yet come. Why do you fear what you yourself will also overcome? Do not let the weakness that I have accepted disturb you. I was anxious for you, but you should not worry about me.”

SERMON 54.5.1

Luke 23:34

The very appearance of the gallows showed the criterion that he would apply when he comes to judge everyone. The believing thief’s faith prefigured those who would be saved, while the blasphemer’s wickedness foreshadowed those who would be condemned. Christ’s passion, therefore, contains the mystery of our salvation.

SERMON 55.1

Luke 23:43

This cross of Christ holds the mystery of its true and prophesied altar. There, through the saving victim, a sacrifice of human nature is celebrated. There the blood of a spotless lamb dissolved the pact of that ancient transgression. There the whole perversity of the devil’s mastery was abolished, while humility triumphed as conqueror over boasting pride. The effect of faith was so swift that one of the two thieves crucified with Christ who believed in the Son of God entered paradise justified.Who could explain the mystery of such a great gift? Who could describe the power of such a marvelous transformation? In a brief moment of time, the guilt of a longstanding wickedness was abolished. In the middle of the harsh torments of a struggling soul, fastened to the gallows, that thief passes over to Christ, and the grace of Christ gives a crown to him, someone who incurred punishment for his own wickedness.

SERMON 55.3

Luke 23:43

Until now, one [thief] was the equal in all things of his companion. He was a robber on the roads and always a danger to the safety of people. Deserving the cross, he suddenly becomes a confessor of Christ.… “Remember me, Lord, when you enter into your kingdom.” …Then came the gift in which faith itself received a response. Jesus said to him, “Truly, I say to you, today you will be with me in paradise.” This promise surpasses the human condition, because it did not come so much from the wood of a cross as from a throne of power. From that height, he gives a reward to faith. There he abolishes the debt of human transgression, because the “form of God” did not separate itself from the “form of a servant.” Even in the middle of this punishment, both the inviolable divinity and the suffering human nature preserved its own character and its own oneness.

SERMON 53.1.2

Luke 24:9-11

The Spirit of truth would by no means have permitted this hesitation, wavering in human weakness, to enter the hearts of his preachers, if their trembling anxiety and questioning delay were not to have established the foundations of our faith. Consequently it was our doubts and our danger that was being considered in the apostles. We, in the guise of the apostles, were being instructed against the slanders of the wicked and the proofs of earthly wisdom. Their “seeing” instructed us, their “hearing” informed us, their “touching” strengthened us. Let us give thanks for the divine plan and the necessary “slowness” of the holy fathers. They “doubted” so that we need not doubt.

SERMON 73.1.2.444

Luke 24:36-43

The resurrection of the Lord was truly the resurrection of a real body, because no other person was raised than he who had been crucified and died. What else was accomplished during that interval of forty days than to make our faith entire and clear of all darkness? For a while, he spoke with his disciples and remained with them, ate with them and allowed himself to be felt with careful and inquisitive touch by those who were under the influence of doubt. This was his purpose in going in to them when the doors were shut. He gave them the Holy Ghost by his breath. After giving them the light of intelligence, he opened the secrets of holy Scripture. In his same person, he showed them the wound in the side, the prints of the nails and all the fresh tokens of the passion. He said, “See my hands and feet. It is I myself. Handle me and see. A spirit does not have flesh and bones, as you see that I have.” He did all this so that we might acknowledge that the properties of the divine and the human nature remain in him without causing a division. We now may know that the Word is not what the…

We now may know that the Word is not what the flesh is. We may now confess that the one Son of God is Word and flesh.

TOME 5

Luke 24:50-53

Dearly beloved, through all this time between the resurrection of the Lord and his ascension, the providence of God thought of this, taught this and penetrated their eyes and heart. He wanted them to recognize the Lord Jesus Christ as truly risen, who was truly born, truly suffered and truly died. The manifest truth strengthened the blessed apostles and all the disciples who were frightened by his death on the cross and were doubtful of his resurrection. The result was they were not only afflicted with sadness but also were filled with “great joy” when the Lord went into the heights of heaven.It was certainly a great and indescribable source of joy when, in the sight of the heavenly multitudes, the nature of our human race ascended over the dignity of all heavenly creatures. It passed the angelic orders and was raised beyond the heights of archangels. In its ascension, our human race did not stop at any other height until this same nature was received at the seat of the eternal Father. Our human nature, united with the divinity of the Son, was on the throne of his glory. The ascensio…

In its ascension, our human race did not stop at any other height until this same nature was received at the seat of the eternal Father. Our human nature, united with the divinity of the Son, was on the throne of his glory.
The ascension of Christ is our elevation. Hope for the body is also invited where the glory of the Head preceded us. Let us exult, dearly beloved, with worthy joy and be glad with a holy thanksgiving. Today we not only are established as possessors of paradise, but we have even penetrated the heights of the heavens in Christ. The indescribable grace of Christ, which we lost through the “ill will of the devil,” prepared us more fully for that glory. Incorporated within himself, the Son of God placed those whom the violent enemy threw down from the happiness of our first dwelling at the right hand of the Father. The Son of God lives and reigns with God the Father almighty and with the Holy Spirit forever and ever. Amen.

SERMON 73.3-4

Mark 14:60-65

(Serm. 5. de Pass.) But Caiaphas, to increase the odiousness of what they had heard rent his clothes, and without knowing what his frantic action meant, by his madness, deprived himself of the honour of the priesthood, forgetting that command, by which it is said of the High Priest, He shall not uncover his head or rend his clothes. For there follows: Then the High Priest rent his clothes, and saith, What need we any further witnesses? Ye have heard the blasphemy: what think ye?

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Mark 16:19

And so while at Easter it was the Lord’s resurrection which was the cause of our joy, our present rejoicing is due to his ascension into heaven. With all due solemnity we are commemorating that day on which our poor human nature was carried up in Christ above all the hosts of heaven, above all the ranks of angels, beyond those heavenly powers to the very throne of God the Father. It is upon this ordered structure of divine acts that we have been firmly established, so that the grace of God may show itself still more marvelous when, in spite of the withdrawal from our sight of everything that is rightly felt to command our reverence, faith does not fail, hope is not shaken, charity does not grow cold.… It was in order that we might be capable of such blessedness that on the fortieth day after his resurrection, after he had made careful provision for everything concerning the preaching of the gospel and the mysteries of the new covenant, our Lord Jesus Christ was taken up to heaven before the eyes of his disciples, and so his bodily presence among them came to an end. From that time on…

From that time onward he was to remain at the Father’s right hand until the completion of the period ordained by God for the church’s children to increase and multiply, after which, in the same body with which he ascended, he will come again to judge the living and the dead. And so our redeemer’s visible presence has passed into the sacraments. Our faith is nobler and stronger because empirical sight has been replaced by a reliable teaching whose authority is accepted by believing hearts, enlightened from on high.

SERMON 74.1-2

Matthew 1:1

(Epist. 59. ad Const. Id. Ep. 83. ad Palest.) We do not speak of Christ as man in such a sort as to allow that any thing was wanting to Him, which it is certain pertains to human nature, whether soul, or rational mind, or flesh, and flesh such as was taken of the Woman, not gained by a change or conversion of the Word into flesh. These three several errors, that thrice false heresy of the Apollinarists has brought forward. Eutyches also chose out this third dogma of Apollinaris, which denying the verity of the human body and soul, maintained that our Lord Jesus Christ was wholly and entirely of one nature, as though the Divine Word had changed itself into flesh and soul, and as though the conception, birth, growth, and such like, had been undergone by that Divine Essence, which was incapable of any such changes with the very and true flesh; for such as is the nature of the Only-begotten, such is the nature of the Father, and such is the nature of the Holy Ghost, both impassible and eternal. But if to avoid being driven to the conclusion that the Godhead could feel suffering and death…

But if to avoid being driven to the conclusion that the Godhead could feel suffering and death, he departs from the corruption of Apollinaris, and should still dare to affirm the nature of the incarnate Word, that is of the Word and the flesh, to be the same, he clearly falls into the insane notions of Manichæus and Marcion, and believes that the Lord Jesus Christ did all His actions with a false appearance, that His body was not a human body, but a phantasm, which imposed on the eyes of the beholders.

(Ep. 35. ad Julian.) But what Eutyches ventured to pronounce as an episcopal decision, that in Christ before His incarnation were two natures, but after His incarnation only one, it behoved that he should have been urgently pressed to give the reason of this his belief. I suppose that in using such language he supposed the soul which the Saviour took, to have had its abode in heaven before it was born of the Virgin Marye. This Catholic hearts and ears endure not, for that the Lord when He came down from heaven showed nothing of the condition of human nature, nor did He take on Him any soul that had existed before, nor any flesh that was not taken of the flesh of His mother. Thus what was justly condemned in Origenf, must needs be rebuked in Eutyches, to wit, that our souls before they were placed in our bodies had actions not only wonderful but various.

Matthew 1:22-23

(Serm. xxiii. 1.) The conception was by the Holy Spirit within the womb of the Virgin; who, as she conceived in perfect chastity, in like manner brought forth her Son.

(as quoted by Aquinas, AD 1274) Catena Aurea by Aquinas

Matthew 1:25

And by a new nativity He was begotten, conceived by a Virgin, born of a Virgin, without paternal desire, without injury to the mother's chastity... for a Virgin conceived, a Virgin bare, and a Virgin she remained.

Sermon 22:2

Matthew 2:1-2

(Serm. xxxiii. 2.) Christ Himself, the expectation of the nations, that innumerable posterity once promised to the most blessed patriarch Abraham, but to be born not after the flesh, but by the Spirit; therefore likened to the stars for multitude, that from the father of all nations, not an earthly but an heavenly progeny might be looked for. Thus the heirs of that promised posterity, marked out in the stars, are roused to the faith by the rise of a new star, and where the heavens had been at first called in to witness, the aid of Heaven is continued. (Serm. xxxiv. 3.) Besides that star thus seen with the bodily eye, a yet brighter ray of truth pierced their hearts; they were enlightened by the illumination of the true faith. (ubi sup.) What they knew and believed might have been sufficient for themselves, that they needed not to seek to see with the bodily eye, what they saw so clearly with the spiritual.
