Leo the Great — Commentary on Scripture

Psalms 27:1

In rendering service to the grace of God, we are not only made subject to our King through obedience but are even joined to him through the will. If we are of one mind with him (willing what he wills, disapproving of what he disapproves), he himself will bring us victory in all our battles. He who has given the “will” will bestow also the ability. In this way can we “cooperate” with his works, speaking that prophetic utterance in the exultation of faith: “The Lord is my light and my salvation. Whom shall I fear? The Lord is the defender of my life. Of whom shall I be afraid?”

SERMON 26:4.2

Psalms 34:8

God’s people have spiritual feasts and pure delicacies that it is healthy for them to look for and laudable for them to desire, for the prophet says in praise of them, “Taste and see that the Lord is sweet.” Whoever have touched with the taste of their hearts the sweetness of the justice and mercy of God, by which all his ordinances are carried out, and have drunk from the experiences of supernal joys never to be diminished by any pride, they will despise the corruptible and temporal good in their admiration of the eternal, and they will glow in that fire that the love of God kindles. As when cold is changed to warmth and night is changed to daylight, the Holy Spirit by one stroke in the hearts of the faithful takes away darkness and destroys sin.

SERMON 50:2

Psalms 41:1

You should “recognize” Christ “in the needy” to the extent that your resources “allow.” Christ our Lord gives testimony to the fact that he is the one whom we clothe, support and feed in them. That is how strongly he has recommended the poor to us.

SERMON 6:2

Psalms 43:3

The beam that emanates from light does not come after the light. True light never lacks a beam, having it as part of its substance to shine, just as it always has it as part of its substance to exist. But the manifestation of this beam has been called a “sending,” by which Christ appeared to the world. Although he filled all things with his invisible majesty, he came, nevertheless, to those who had not known him, as if from a very remote and deep seclusion. At that time, he took away the blindness of ignorance, as it has been written: “For those sitting in darkness and in the shadow of death, a light has risen.” Of course the light of truth has been sent out in prior ages to enlighten the holy fathers and prophets, as when David said, “Send out your light and your truth.” Of course the divinity of the Son has made clear the works of his presence “in various ways and by many signs.” Yet all these prefigurations and all these miracles bore testimony about that “sending” of which the apostle speaks: “When the fullness of time came, God sent his Son, made from a woman, made under the Law…

SERMON 25:3.2-4:1

Psalms 55:19-23

May human obedience never withdraw itself from the grace of God, nor may it fall from that good without which it cannot be good. If it feels anything impossible for itself or arduous in the performance of the commandments, let it not abide in itself but return to the one who commanded it, for he gives an order to excite desire and afford help, as the prophet says: “Cast your care on the Lord, and he himself will support you.” Are there any so immoderately proud that they assume themselves to be so perfectly untouched and unstained that they need no renewal? Such an opinion is thoroughly mistaken, and they grow old in excessive vanity if, among the temptations of this life, they believe themselves immune from every wound. Everything is full of danger, everything full of pitfalls. Desires drive us, enticements lure us, money attracts us, loss hinders us, and the tongues of slanderers are bitter. The mouths of those who praise us are not always trustworthy; here hate rages, there a lying service deceives, so that it is easier to avoid discord than to escape falsehood.

SERMON 43:1

Psalms 69:20-29

You have truly and in very many places read something that pertains to the detestable wickedness of your crime and to the voluntary suffering of the Lord. He himself speaks through Isaiah: “I gave my back to the scourges, my cheeks to striking hands; my face I did not shield from the insult of spittle.” He says through David, “They put gall in my food, and in my thirst they gave me vinegar to drink.” On yet another occasion, he says through David, “Many dogs surround me, a pack of evildoers closes in on me. They have pierced my hands and my feet, they have numbered all my bones. They watched me carefully and examined me. They divided my garments among them and cast lots for my clothes.” Lest only the kind of your crime might seem to be predicted and the power of the crucified one not foretold, you certainly did not read that the Lord descended from the cross. You did, however, read, “The Lord has reigned from the cross.”

SERMON 55:2

Psalms 69:30-32

Always indeed, dearly beloved, “the earth is full of the Lord’s kindness,” and the nature of things itself is the teacher to each one of the faithful in the worship of God, while “heaven and earth, the sea and all things that are in them” proclaim the goodness and power of their Creator. The wonderful beauty of the elements that serve him demands a due thanksgiving from the understanding creature.

SERMON 44:1

Psalms 73:1-3

Although the hearts of all the faithful do not doubt that divine providence is never absent in any part of the world or at any time or that success in temporal affairs does not rest on the power of the stars (which is no power) but it acknowledges that all things are disposed according to the most just and most kind decision of the King on High, as it is written: “All the paths of the Lord are mercy and truth.” Still, since some things do not happen according to our desires, and since the cause of the wicked is often favored over that of the righteous in the mistakes of human justice, it is a fact very near to us and well known that these things trouble even great souls and drive them to some complaint of an unlawful matter. Even David, most renowned of prophets, confessed himself distressed by these diversities to the point of danger and said, “My feet were almost stumbling, my steps were all but slipping, because I was envious of the arrogant, seeing the prosperity of the sinners.”

SERMON 43:2

Psalms 77:5-10

What mind can understand this mystery, what tongue has the capability of explaining this grace? Iniquity turns back into innocence, oldness into newness. Strangers come into adoption, and foreigners enter on an inheritance. Godless people have started to be just, the covetous to be beneficent, the incontinent to be chaste, the “earthly” to be “heavenly.” What has effected “this change” but the “right hand of the Most High”? For “the Son of God came to undo the devil’s works.” He grafted himself into us and us into himself in such a way that God’s descent to human affairs became the elevation of human beings to those divine.

SERMON 27:2.2

Psalms 116:15

Renounce pleasure, turn away from uncleanness, dispel luxury, flee unrighteousness, resist falsehood. When you see that you are waging a battle on many fronts, then you must also, in imitation of the martyrs, pursue a many-sided victory. Every time we die to sins, the sins die in us, and this “death of his holy ones is precious in the sight of the Lord,” because a “human being” dies “to the world” not by the destruction of senses but by the death of vices.

SERMON 84B.2

Psalms 116:15

Your blessed co-apostle, Paul, “vessel of election” and special teacher of the nations, coming to this city, was your associate at that time when all innocence, all honor, all liberty was suffering under the will of Nero. Nero’s rage, inflamed by an excess of all vices, in this time drove him up to such a flood of insanity that he was the first to bring on the honor of a general persecution for the name of Christian. He seemed to think that the grace of God might be cut off through the slaughter of God’s holy ones. Nero did not know that the religion founded on the mystery of the cross cannot be extinguished by any kind of cruelty, since “precious in the sight of the Lord is the death of his saints.” This does not diminish, but it increases, the church. As if the grace of God could be blotted out by the slaughter of his holy ones, for whom it was the greatest profit that the contempt of this failing life brought the knowledge of eternal happiness. Therefore this failing life brought the knowledge of eternal happiness. Therefore “precious in the sight of the Lord is the death of his s…

SERMON 82:6

Psalms 130:7

But satisfaction must not be ruled out or absolution denied to those who in time of necessity or in the moment of pressing danger beg for the protection of penance followed by absolution. For we cannot put limitations on the mercy of God or fix limits to times. With him there is no delaying of pardon when the conversion is genuine, as the Spirit of God says through the prophet: “If being converted you lament, you will be saved”; and elsewhere: “Tell me your sins first in order that you may be justified”;7 and again: “Because with the Lord there is mercy; and with him plentiful redemption.” Consequently, we must not be stingy in dispensing the gifts of God or disregard the tears and groans of those accusing themselves, since, in our opinion, the very desire for penance was conceived through the inspiration of God, as the apostle says: “Lest by chance God give them repentance … so that they may recover themselves from the snare of the devil, at whose pleasure they are held captive.”

LETTER 108

Psalms 144:5-7

The psalmist is a witness of this matter when he says, “All have gone astray together; they have become worthless.” And Christ’s prophets, praying for help, said, “Lord, bow down your heavens and descend”; not that he might change the places in which all things are now located but that he might take on the flesh of human weakness for our salvation. Paul says the same thing: “How, being rich, he became poor for our sakes, that by his poverty we might become rich.” And he came to the earth and proceeded as a man from the virgin’s womb, which he sanctified. Confirming by this process the interpretation of his name, Emmanuel, that is, “God with us,” he began in a marvelous way to be what we are and did not cease to be what he was. He assumed our nature in such a way as not to lose what he himself was.

TESTIMONIA 19

Psalms 145:14-16

Whoever finds the healing of correction to be difficult should flee to the mercy of God for help and beg that the chains of evil habit be broken away from them, for “the Lord lifts up all who collapse and raises up all who have been broken down.” No, the prayer of a believer will not be empty, since our merciful God “will accomplish the intentions of those who fear him.” He will give what has been asked for, since he provided the inspiration to ask it. Through our Lord Jesus Christ, living and reigning with the Father and the Holy Spirit forever and ever. Amen.

SERMON 36:4.2

Psalms 146:7-9

We not only do not hold back, but even encourage, compassion, wisely and divinely set up by the church, that even for such people you should pray to the Lord with us. We also, with tears of sorrow, have pity on the downfall of misled souls. Following the example of the apostle’s compassion, “we are made weak with the weak,” and “we weep with those who weep.” We hope that the mercy of God may be gained with many tears and requisite satisfaction on the part of those who have lapsed. While we live in this body, no one’s rehabilitation is to be despaired of. We should desire the amendment of all, with the Lord helping us, who “raises up those who have been broken down, sets captives free, gives sight to the blind,” to whom is honor and glory “with the Father and with the Holy Spirit” forever and ever. Amen.

SERMON 34:5.2

Romans 8:34

If the true high priest does not atone for us, using the nature proper to us, and the true blood of the spotless Lamb does not cleanse us, then a true priesthood and true sacrifices do not exist in any other way in God’s church, which is the body of Christ. Although he is seated at the right hand of the Father, he performs the sacrament of the atonement in the same flesh which he assumed from the Virgin Mary.

LETTER 80

Romans 12:5

The bond of our unity cannot be firm unless the bond of charity has tied us together in indivisible solidarity.… It is the connection of the entire body which makes for one health, one beauty. And this connection requires the unanimity of the entire body, but especially it demands harmony among the bishops.

LETTER 14

Titus 1:16

Our peace also has its dangers, dearly beloved. In vain do people feel secure as a result of freedom for their faith if they do not resist the desires of vice. By the quality of works is the human heart made known, and outward actions disclose the beauty of souls. There are some, as the apostle says, who “profess to know God but deny him through their deeds.” Truly the guilt of denial is incurred when the ears have heard what is good but the conscience does not hold on to it. The frailty of the human condition easily slides into sin.

SERMONS 36.4

Titus 2:11

It is, therefore, with an unmistakable tenderness that so great a wealth of divine goodness has been poured out on us, dearly beloved. Not only has the usefulness of foregoing examples served for calling us to eternity, but the Truth himself has even “appeared” in a visible body. We ought, then, to celebrate this day of the Lord’s birth with no listless and worldly joy.

SERMONS 23.5

Titus 3:4

By the delay of his saving work, he has made us better disposed to accept his calling. In this is shown the “goodness and kindness of God.” By this means, what had been foretold through so many ages by numerous signs, numerous words and numerous mysteries would no longer be open to doubt in these days of the gospel. That way, the birth of the Savior—which was to exceed all wonders and the whole measure of human intelligence—would engender in us a faith all the more steadfast, the more often and the earlier it had been proclaimed beforehand.
