Leo, the bishop, to the whole body of monks settled throughout Palestine.
The anxious care, which I owe to the whole Church and to all its sons, has ascertained from many sources that some offence has been given to your minds, beloved, through my interpreters(1) , who being either ignorant, as it appears, or malicious, have made you take some of my statements in a different sense to what I meant, not being capable of turning the Latin into Greek with proper accuracy, although in the explanation of subtle and difficult matters, one who undertakes to discuss them can scarcely satisfy himself even in his own tongue. And yet this has so far been of advantage to me, that by your disapproving of what the catholic Faith rejects, we know you are greater friends to the true than to the false: and that you quite properly refuse to believe what I myself also abhor, in accordance with ancient doctrine(2) . For although my letter addressed to bishop Flavian, of holy memory, is of itself sufficiently explicit, and stands in no need either of correction or explanation, yet other of my writings harmonize with that letter, and in them my position will be found similarly set forth. For necessity was laid upon me to argue against the heretics who have thrown many of Christ's peoples into confusion, both before our most merciful princes and the holy synodal Council, and the church of Constantinople, and thus I have laid down what we ought to think and feel on the Incarnation of the Word according to the teaching of the Gospel and Apostles, and in nothing have I departed from the creed of the holy Fathers: because the Faith is one, true, unique, catholic, and to it nothing can be added, nothing taken away: though Nestorius first, and now Eutyches, have endeavoured to assail it from an opposite standpoint, but with similar disloyalty, and have tried to impose on the Church of God two contradictory heresies, which has led to their both being deservedly condemned by the disciples of the Truth; because the false view which they both held in different ways was exceedingly mad and sacrilegious.
II. Eutyches, Who Confounds the Persons, is as Much to Be Rejected as Nestorius, Who Separates Them(3) .
Nestorius, therefore, must be anathematized for believing the Blessed Virgin Mary to be mother of His manhood only, whereby he made the person of His flesh one thing, and that of His Godhead another, and did not recognize the one Christ in the Word of God and in the flesh, but spoke of the Son of God as separate and distinct from the son of man: although, without losing that unchangeable essence which belongs to Him together with the Father and the Holy Spirit from all eternity and without respect of time, the "Word became flesh" within the Virgin's womb in such wise that by that one conception and one parturition she was at the same time, in virtue of the union of the two substances, both handmaid and mother of the Lord. This Elizabeth also knew, as Luke the evangelist declares, when she said: "Whence is this to me that the mother of my Lord should come to me(4) ?" But Eutyches also must be stricken with the same anathema, who, becoming entangled in the treacherous errors of the old heretics, has chosen the third dogma of Apollinaris(5) : so that he denies the reality of his human flesh and Soul, and maintains the whole of our Lord Jesus Christ to be of one nature, as if the Godhead of the Word had turned itself into flesh and soul: and as if to be conceived and born, to be nursed and grow, to be crucified and die, to be buried and rise again, and to ascend into heaven and to sit on the Father's right hand, from whence He shall come to judge the living and the dead-as if all those things belonged to that essence only which admits of none of them without the reality of the flesh: seeing that the nature of the Only-begotten is the nature of the Father, the nature of the Holy Spirit, and that the undivided unity and consubstantial equality of the eternal Trinity is at once impassible and unchangeable. But if(6) this heretic withdraws from the perverse views of Apollinaris, lest he be proved to hold that the Godhead is passible(7) and mortal: and yet dares to pronounce the nature of the Incarnate Word that is of the Word made Flesh one, he undoubtedly crosses over into the mad view of Manichaeus(8) and Marcion(9) , and believes that the man Jesus Christ, the mediator between God and men, did all things in an unreal way, and had not a human body, but that a phantom-like apparition presented itself to the beholders' eyes.
As these iniquitous lies were once rejected by the catholic Faith, and such men's blasphemies condemned by the unanimous votes of the blessed Fathers throughout the world, whoever these are that are so blinded and strange to the light of truth as to deny the presence of human, that is our, nature in the Word of God from the time of the Incarnation, they must show on what ground they claim the name of Christian, and in what way they harmonize with the true Gospel, if the child-bearing of the blessed Virgin produced either the flesh without the Godhead or the Godhead without the flesh. For as it cannot be denied that "the Word became flesh and dwelt in us(10) ," so it cannot be denied that "God was in Christ, reconciling the world to Himself(11) ." But what reconciliation can there be, whereby God might be propitiated for the human race, unless the mediator between God and man took up the cause of all? And in what way could He properly fulfil His mediation, unless He who in the form of God was equal to the Father, were a sharer of our nature also in the form of a slave: so that the one new Man might effect a renewal of the old: and the bond of death fastened on us by one man's wrong-doing(12) might be loosened by the death of the one Man who alone owed nothing to death. For the pouring out of the blood of the righteous on behalf of the unrighteous was so powerful in its effect(13) , so rich a ransom that, if the whole body of us prisoners only believed in their Redeemer, not one would be held in the tyrant's bonds: since as the Apostle says, "where sin abounded, grace also did much more abound(14) ." And since we, who were born under the imputation(15) of sin, have received the power of a new birth unto righteousness, the gift of liberty has become stronger than the debt of slavery.
What hope then do they, who deny the reality of the human person in our Saviour's body, leave for themselves in the efficacy of this mystery? Let them say by what sacrifice they have been reconciled, by what blood-shedding brought back. Who is He "who gave Himself for us an offering and a victim to God for a sweet smell(16) :" or what sacrifice was ever more hallowed than that which the true High priest placed upon the altar of the cross by the immolation of His own flesh? For although in the sight of the Lord the death of many of His saints has been precious(17) , yet no innocent's death was the propitiation of the world. The righteous have received, not given, crowns: and from the endurance of the faithful have arisen examples of patience, not the gift of justification. For their deaths affected themselves alone, and no one has paid off another's debt by his own death(18) : one alone among the sons of men, our Load Jesus Christ, stands out as One in whom all are crucified, all dead, all buried, all raised again. Of them He Himself said "when I am lifted from the earth, I will draw all (things) unto Me(19) ." True faith also, that justifies the transgressors and makes them just, is drawn to Him who shared their human natures and wins salvation in Him, in whom alone man finds himself not guilty; and thus is free to glory in the power of Him who in the humiliation of our flesh engaged in conflict with the haughty foe, and shared His victory with those in whose body He had triumphed.
Although therefore in our one Lord Jesus Christ, the true Son of God and man, the person of the Word and of the flesh is one, and both beings have their actions in common(20) : yet we must understand the character of the acts themselves, and by the contemplation of sincere faith distinguish those to which the humility of His weakness is brought from those to which His sublime power is inclined: what it is that the flesh without the Word or the Word without the flesh does not do. For instance, without the power of the Word the Virgin would not have conceived nor brought forth: and without the reality of the flesh His infancy would not have laid wrapt in swaddling clothes. Without the power of the Word the Magi would not have adored the Child that a new star had pointed out to them: and without the reality of the flesh that Child would not have been ordered to be carried away into Egypt and withdrawn from Herod's persecution. Without the power of the Word the Father's voice uttered from the sky would not have said, "This is My beloved Son, in whom I am well pleased(21) :" and without the reality of the flesh John would not have been able to point to Him and say: "Behold the Lamb of God, behold Him that beareth away the sins of the world(22) ." Without the power of the Word there would have been no restoring of the sick to health, no raising of the dead to life: and without the reality of the flesh He would not have hungered and needed food, nor grown weary and needed rest. Lastly, without the power of the Word, the Lord would not have professed Himself equal to the Father, and without the reality of the flesh He would not also have said that the Father was greater than He: for the catholic Faith upholds and defends both positions, believing the only Son of God to be both Man and the Word according to the distinctive properties of His divine and human substance.
VI. There is No Confusion of the Two Natures in Christ(23) .
Although therefore from that beginning whereby in the Virgin's womb "the Word became flesh," no sort of division ever arose between the Divine and the human substance, and through all the growth and changes of His body, the actions were of one Person the whole time, yet we do not by any mixing of them up confound those very acts which were done inseparably: and from the character of the acts we perceive what belonged to either form. For neither do His Divine acts affect(24) His human, nor His human acts His Divine, since both concur in this way and to this very end that in their operation His twofold qualities be not absorbed the one by the other, nor His individuality doubled. Therefore let those Christian phantom-mongers(25) tell us, what nature of the Saviour's it was that was fastened to the wood of the Cross, that lay in the tomb, and that on the third day rose in the flesh when the stone was rolled away from the grave: or what kind of body Jesus presented to His disciples' eyes entering when the doors were shut upon them: seeing that to drive away the beholders' disbelief, He required them to inspect with their eyes and to handle with their hands the still open prints of the nails and the flesh wound of His pierced side. But if in spite of the truth being so clear, their persistence in heresy will not abandon their position in the darkness, let them show whence they promise themselves the hope of eternal life, which no one can attain to, save through the mediator between God and man, the man Jesus Christ. For "there is not another name given to men under heaven, in which they must be saved(26) ." Neither is there any ransoming of men from captivity, save in His blood, "who gave Himself a ransom for all(27) :" who, as the blessed apostle proclaims, "when He was in the form of God, thought it not robbery that He was equal with God; but emptied Himself, receiving the form of a slaves Icing made in the likeness of men, and being found in fashion as a man He humbled Himself, being made obedient even unto death, the death of the cross. For which reason God also exalted Him, and gave Him a name which is above every name: that in the name of Jesus every knee may bow of things in heaven, of things on the earth, and of things under the earth, and that every tongue may confess that the Lord Jesus Christ is in the glory of God the Father(28) ."
(29) Although therefore the Lord Jesus Christ is one, and the true Godhead and true Manhood in Him forms absolutely one and the same person, and the entirety of this union cannot be separated by any division, yet the exaltation wherewith "God exalted Him," and "gave Him a name which excels every name," we understand to belong to that form which needed to be enriched by this increase of glory(30) . Of course "in the form of God" the Son was equal to the Father, and between the Father and the Only-begotten there was no distinction in point of essence, no diversity in point of majesty: nor through the mystery(31) of the Incarnation had the Word been deprived of anything which should be restored Him by the Father's gift. But "the form of a slave" by which the impassible Godhead fulfilled a pledge of mighty loving-kindness(32) , is human weakness which was lifted up into the glory of the divine power, the Godhead and the manhood being right from the Virgin's conception so completely united that without the manhood the divine acts, and without the Godhead the human acts were not performed. For which reason as the Lord of majesty is said to have been crucified, so He who from eternity is equal with God is said to have been exalted. Nor does it matter by which substance Christ is spoken of, since the unity of His person inseparably remaining He is at once both wholly Son of man according to the flesh and wholly Son of God according to His Godhead, which is one with the Father. Whatever therefore Christ received in time, He received in virtue of His manhood, on which are conferred whatsoever it had not. For according to the power of the Word, "all things that the Father hath" the Son also hath indiscriminately, and what "in the form of a slave" He received from the Father, He also Himself gave in the form of the Father. He is in Himself at once both rich and poor; rich, because "in the beginning was the Word, and the Word was with God, and God was the Word. This was in the beginning with God. All things were made through Him, and without Him was made nothing:" and poor because "the Word became flesh and dwelt in us(33) ." But what is that emptying of Himself, or that poverty except the receiving of the form of a slave by which the majesty of the Word was veiled, and the scheme for man's redemption carried out? For as the original chains of our captivity could not be loosed, unless a man of our race and of our nature appeared who was not under the prejudice of the old debt, and who with his untainted blood might blot out the bond of death(34) , as it had from the beginning been divinely fore-ordained, so it came to pass in the fulness of the appointed time that the promise which had been proclaimed in many ways might reach its long expected fulfilment, and that thus, what had been frequently announced by one testimony after another, might have all doubtfulness removed.
And so, as all these heresies have been destroyed, which through the holy devotion of the presiding Fathers have been cut off from the body of the catholic unity, and which deserved to be exiles from Christ, because they have made the Incarnation of the Word, which is the one salvation of those who believe aright, a stone of offence and a stumbling-block to themselves, I am surprised that you, beloved, have any difficulty in discerning the light of the Truth. And since it has been made clear by numerous explanations that the Christian Faith was right in condemning both Nestorius and Eutyches with Dioscorus, and that a man cannot be called a Christian who gives his assent to the blasphemous opinion of either the one or the other, I am grieved that you are, as I hear, doing despite to the teaching of the Gospel and the Apostles by stirring up the various bodies of citizens with seditions, by disturbing the churches, and by inflicting not only insults, but even death, upon priests and bishops, so that you lose sight of your resolves and profession(35) through your fury and cruelty. Where is your rule of meekness and quietness? where is the long-suffering of patience? where the tranquillity of peace? where the firm foundation of love and courage of endurance?what evil persuasion has carried you off, what persecution has separated you from the gospel of Christ? or what strange craftiness of the Deceiver has shown itself that, forgetting the prophets and apostles, forgetting the health-giving creed and confession which you pronounced before many witnesses when you received the sacrament of baptism you should give yourselves up to the the Devil's deceits? what effect would "the Claws(36) " and other cruel tortures have had on you if the empty comments of heretics have had so much weight in taking the purity of your faith by storm? you think you are acting for the Faith and yet you go against the Faith. You arm yourselves in the name of the Church and yet fight against the Church. Is this what you have learnt from prophets, evangelists, and apostles? to deny the true flesh of Christ, to subject the ,very essence of the Word to suffering and death, to make our nature different from His who repaired it, and to reckon all that the cross uplifted, that the spear pierced, that the stone on the tomb received and gave back, to be only the work: of Divine power, and not also of human humility? It is in reference to this humility that the Apostle says, "For I do not blush for the Gospel(37) ," inasmuch as he knew what a slur was cast upon Christians by their enemies. And, therefore, the Lord also made proclamation, saying: "he that shall confess Me before men him will I also confess before My Father(38) ." For these will not be worthy of the Son and the Father's acknowledgment in whom the flesh of Christ awakens no respect: and they will prove themselves to have gained no virtue from the sign of the cross(39) who blush to avow with their lips what they have consented to bear upon their brows.
Give up, my sons, give up these suggestions of the devil. God's Truth nothing can impair, but the Truth does not save us except in our flesh. For, as the prophet says, "truth is sprung out of the earth(40) ," and the Virgin Mary conceived the Word in such wise that she ministered flesh of her substance to be united to Him without the addition of a second person, and without the disappearance of her nature: seeing that He who was in the form of God took the form of a slave in such wise that Christ is one and the same in both forms: God bending Himself to the-weak things of man, and man rising up to the high things of the Godhead, as the Apostle says, "whose are the fathers, and from whom, according to the flesh is Christ, who is above all things God blessed for ever. Amen(41) ."
