Easter Sermon of Pope St. Leo the Great

Accordingly, since the Apostle says, “the first man is of the earth earthy, the second man is from heaven heavenly. As is the earthy, such also are they that are earthy; and as is the heavenly, such also are they that are heavenly. As we have borne the image of the earthy, so let us also bear the image of Him Who is from heaven,” we must greatly rejoice over this change, whereby we are translated from earthly degradation to heavenly dignity through His unspeakable mercy, Who descended into our estate that He might promote us to His, by assuming not only the substance but also the conditions of sinful nature, and by allowing the impassibility of Godhead to be affected by all the miseries which are the lot of mortal manhood. And hence that the disturbed minds of the disciples might not be racked by prolonged grief, He with such wondrous speed shortened the three days’ delay which He had announced, that by joining the last part of the first and the first part of the third day to the whole of the second, He cut off a considerable portion of the period, and yet did not lessen the number of days. The Saviour’s Resurrection therefore did not long keep His soul in Hades, nor His flesh in the tomb; and so speedy was the quickening of His uncorrupted flesh that it bore a closer resemblance to slumber than to death, seeing that the Godhead, Which quitted not either part of the Human Nature which He had assumed, reunited by Its power that which Its power had separated.

And then there followed many proofs, whereon the authority of the Faith to be preached through the whole world might be based. And although the rolling away of the stone, the empty tomb, the arrangement of the linen cloths, and the angels who narrated the whole deed by themselves fully built up the truth of the Lord’s Resurrection, yet did He often appear plainly to the eyes both of the women and of the Apostles not only talking with them, but also remaining and eating with them, and allowing Himself to be handled by the eager and curious hands of those whom doubt assailed. For to this end He entered when the doors were closed upon the disciples, and gave them the Holy Spirit by breathing on them, and after giving them the light of understanding opened the secrets of the Holy Scriptures, and again Himself showed them the wound in the side, the prints of the nails, and all the marks of His most recent Passion, whereby it might be acknowledged that in Him the properties of the Divine and Human Nature remained undivided, and we might in such sort know that the Word was not what the flesh is, as to confess God’s only Son to be both Word and Flesh.

The Apostle of the Gentiles, Paul, dearly-beloved, does not disagree with this belief, when he says, “even though we have known Christ after the flesh, yet now we know Him so no more.” For the Lord’s Resurrection was not the ending, but the changing of the flesh, and His substance was not destroyed by His increase of power. The quality altered, but the nature did not cease to exist: the body was made impassible, which it had been possible to crucify: it was made incorruptible, though it had been possible to wound it. And properly is Christ’s flesh said not to be known in that state in which it had been known, because nothing remained passible in it, nothing weak, so that it was both the same in essence and not the same in glory. But what wonder if S. Paul maintains this about Christ’s body, when he says of all spiritual Christians “wherefore henceforth we know no one after the flesh.” Henceforth, he says, we begin to experience the resurrection in Christ, since the time when in Him, Who died for all, all our hopes were guaranteed to us. We do not hesitate in diffidence, we are not under the suspense of uncertainty, but having received an earnest of the promise, we now with the eye of faith see the things which will be, and rejoicing in the uplifting of our nature, we already possess what we believe.

Let us not then be taken up with the appearances of temporal matters, neither let our contemplations be diverted from heavenly to earthly things. Things which as yet have for the most part not come to pass must be reckoned as accomplished: and the mind intent on what is permanent must fix its desires there, where what is offered is eternal.

...Let God’s people then recognize that they are a new creation in Christ, and with all vigilance understand by Whom they have been adopted and Whom they have adopted. Let not the things, which have been made new, return to their ancient instability; and let not him who has “put his hand to the plough” forsake his work, but rather attend to that which he sows than look back to that which he has left behind.

...These thoughts, dearly-beloved, must be kept in mind not only for the Easter festival, but also for the sanctification of the whole life, and to this our present exercise ought to be directed, that what has delighted the souls of the faithful by the experience of a short observance may pass into a habit and remain unalterably, and if any fault creep in, it may be destroyed by speedy repentance.
