Leo the Great

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 flesh is. We may now confess that the one Son of God is Word and flesh.

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 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.

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 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.

(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.

(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, and so for our profit the Magians' eyes looked on the Lord in His cradle.
