Leo the Great — Commentary on Scripture

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…

(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, 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. But their earnestness and perseverance to see the Babe was for our profit. It profited us that Thomas, after the Lord's resurrection, touched and felt the marks of his wounds, an…

(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. But their earnestness and perseverance to see the Babe was for our profit. It profited us that Thomas, after the Lord's resurrection, touched and felt the marks of his wounds, and so for our profit the Magians' eyes looked on the Lord in His cradle.

Matthew 2:3-6

(ubi sup.) Thou art troubled, Herod, without cause. Thy nature cannot contain Christ, nor is the Lord of the world content with the narrow bounds of thy dominion. He, whom thou wouldest not should reign in Judæa, reigns every where.

(Serm. xxxvi. 2.) Herod represents the Devil; who as he then instigated him, so now he unweariedly imitates him. For he is grieved by the calling of the Gentiles, and by the daily ruin of his power.

(Serm. xxxi. 2.) The Magi, judging as men, sought in the royal city for Him, whom they had been told was born a King. But He who took the form of a servant, and came not to judge but to be judged, chose Bethlehem for His birth, Jerusalem for His death.

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

Matthew 2:10-11

(Serm. in Epiph. s. 4. 3.) Though in stature a babe, needing the aid of others, unable to speak, and different in nothing from other infants, yet such faithful witnesses, showing the unseen Divine Majesty which was in Him, ought to have proved most certainly that that was the Eternal Essence of the Son of God that had taken upon Him the true human nature.

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

Matthew 4:3-4

(Serm. 39. 3.) hence he opposed the adversary rather by testimonies out of the Law, than by miraculous powers; thus at the same time giving more honour to man, and more disgrace to the adversary, when the enemy of the human race thus seemed to be overcome by man rather than by God.

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

Matthew 6:16

(Serm. in Epiph. iv. 5.) But that fasting is not pure, that comes not of reasons of continence, but of the arts of deceit.

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

Matthew 6:17-18

(Serm. in Quadr. vi. 2.) Fasting ought to be fulfilled not in abstinence of food only, but much more in cutting off vices. For when we submit ourselves to that discipline in order to withdraw that which is the nurse of carnal desires, there is no sort of good conscience more to be sought than that we should keep ourselves sober from unjust will, and abstinent from dishonourable action. This is an act of religion from which the sick are not excluded, seeing integrity of heart may be found in an infirm body.

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

Matthew 17:4

Excited therefore by these revelations of secret realities, the apostle Peter, spurning the mundane and loathing earthly things, was seized by a certain excess of passion toward a yearning for eternal things. Filled up with the joy of the whole vision, he wished to dwell there with Jesus where he was delighting in Christ’s manifested glory. Thus Peter said, “Lord, it is good for us to be here; if you wish, I will make three booths here, one for you and one for Moses and one for Elijah.” But the Lord did not reply to this suggestion, for it was not wicked but inappropriate, since the world could not be saved except by Christ’s death. And in the Lord’s warning the faith of those who believe is called to account. Among the temptations of this life we should understand that we are to ask for endurance before glory. Good fortune in ruling cannot come before a time of enduring.

SERMON 38.5

Matthew 17:5

A voice from the cloud said, This is my beloved Son, with whom I am well pleased; listen to him. I am manifested through his preaching. I am glorified through his humility. So listen to him without hesitation. He is the truth and the life. He is my strength and wisdom. “Listen to him” whom the mysteries of the law foreshadowed, of whom the mouths of the prophets sang. “Listen to him” who by his blood redeemed the world, who binds the devil and seizes his vessels, who breaks the debt of sin and the bondage of iniquity. “Listen to him” who opens the way to heaven and by the pain of the cross prepares for you the steps of ascent into his kingdom.

SERMON 38.7

Matthew 26:3-5

(Serm. 58, 2.) This precaution of the Chief Priests arose not from reverence for the festival, but from care for the success of their plot; they feared an insurrection at that season, not because of the guilt the populace might thereby incur, but because they might rescue Christ.

(Serm. 58, 1.) We recognise here a providential arrangement whereby the chief men of the Jews, who had often sought occasion of effecting their cruel purposes against Christ, could never yet succeed till the days of the paschal celebration. For it behoved that the things which had long been promised in symbol and mystery should be accomplished in manifest reality, that the typical lamb should be displaced by the true, and one sacrifice embrace the whole catalogue of the varied victims. That shadows should give way to substance, and copies to the presence of the original; victim is commuted for victim, blood is abolished by blood, and the festival of the Law is at once fulfilled and changed.

Matthew 26:6-13

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

Matthew 26:14-16

(Serm. 60.4.) He did not out of any fear forsake Christ, but through lust of money cast Him off; for in comparison of the love of money all our affections are feeble; the soul athirst for gain fears not to die for a very little; there is no trace of righteousness in that heart in which covetousness has once taken up its abode. The traitor Judas, intoxicated with this bane, in his thirst for lucre was so foolishly hardened, as to sell his Lord and Master.

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

Matthew 26:20-25

(Serm. 58.3.) He shows that the conscience of His betrayer was known to Him, not meeting his wickedness with a harsh and open rebuke, that penitence might find a readier way to one who had not been disgraced by public dismissal.

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

Matthew 26:26

(Serm. 58, 3.) Not excluding the traitor even from this mystery, that it might be made manifest that Judas was provoked by no wrong, but that he had been foreknown in voluntary impiety.

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

Matthew 26:39

The disciples were admonished, and the Lord beseeches the Father that they might confront the force of the present temptation with watchful prayer: “My Father, if it be possible, let this cup pass from me; nevertheless not as I will, but as you will.” The first petition arises from weakness, the second from strength: He desired the former based on our nature and chose the latter based on his own. Equal to the Father, the Son knew that all things were possible to God; rather, he descended into this world to take up the cross against his will so that he might suffer through this conflict of emotions with a disquieted mind. But in order to show the distinction between the receiving nature and the received nature, what was proper of humanity desired divine intervention and what was proper of God looked upon the human situation. The lower will yielded to the higher will, and this demonstrated what the fearful person may pray for and what the divine healer should not grant. “For we do not know how to pray as we ought,” and it is good for us that what we want, for the most part, is not gran…

God, who is good and just, shows mercy toward us by denying us those things we ask for which are harmful.

SERMON 43.2.26

Matthew 26:39-44

(Serm. 58, 5.) This speech of the Head is the health of the whole body, this saying is instruction to the faithful, animates the confessor, crowns the martyr. For who could vanquish the hatred of the world, or the whirlwind of temptations, or the terrors of the persecutors, if Christ did not in all and for all say to the Father, Thy will be done. Let all the sons of the Church then utter this prayer, that when the pressure of some mighty temptation lies upon them, they may embrace endurance of the suffering, disregarding its terrors.

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

Matthew 26:51-54

(Serm. 22.) The Lord of the zealous Apostle will not suffer his pious feeling to proceed further, Then saith Jesus unto him, Put up again thy sword into his place. For it was contrary to the sacrament of our redemption that He, who had come to die for all, should refuse to be apprehended. He gives therefore licence to their fury against Him, lest by putting off the triumph of His glorious Cross, the dominion of the Devil should be made longer, and the captivity of men more enduring.

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

Matthew 26:65

To emphasize his alarm over the words he had just heard, Caiaphas “tore his garments.” Unaware of his own madness, he deprived himself of priestly honor. Caiaphas, where does reason reside in your mind?… You are oblivious to the command you read concerning high priests: “Do not let the hair of your heads hang loose, and do not rend your clothes.” But you, who have now forfeited your dignity, are the very object of disgrace. And in token of the end of the old regulation, the same rending that rips your priestly attire will soon also tear apart the veil of the temple.
