Leo the Great reflects on the passion of Jesus Christ and sees in it not shame, but glory. He sees in the cross not weakness, but power. In his passion and death on the cross, Jesus fulfills all the sacrifices of the Old Covenant which were no more than foreshadowings of what happened on Calvary.
Our understanding, which is enlightened by the Spirit of truth, should receive with purity and freedom of heart the glory of the cross as it shines in heaven and on earth. It should see with inner vision the meaning of the Lord’s words when he spoke of the imminence of his passion: The hour has come for the Son of Man to be glorified. Afterward he said: Now my soul is troubled, and what am I to say? Father, save me from this hour. But it was for this that I came to this hour. Father, glorify your Son. When the voice of the Father came from heaven, saying, I have glorified him, and will glorify him again, Jesus said in reply to those around him: It was not for me that this voice spoke, but for you. Now is the judgment of the world, now will the prince of this world be cast out. And I, if I am lifted up from the earth, will draw all things to myself.
How marvelous the power of the cross; how great beyond all telling the glory of the passion: here is the judgement-seat of the Lord, the condemnation of the world, the supremacy of Christ crucified.
Lord, you drew all things to yourself so that the devotion of all peoples everywhere might celebrate, in a sacrament made perfect and visible, what was carried out in the one temple of Judea under obscure foreshadowings.
Now there is a more distinguished order of Levites, a greater dignity for the rank of elders, a more sacred anointing for the priesthood, because your cross is the source of all blessings, the cause of all graces. Through the cross the faithful receive strength from weakness, glory from dishonor, life from death.
The different sacrifices of animals are no more: the one offering of your body and blood is the fulfillment of all the different sacrificial offerings, for you are the true Lamb of God: you take away the sins of the world. In yourself you bring to perfection all mysteries, so that, as there is one sacrifice in place of all other sacrificial offerings, there is also one kingdom gathered from all peoples.
Dearly beloved, let us then acknowledge what Saint Paul, the teacher of the nations, acknowledged so exultantly: This is a saying worthy of trust, worthy of complete acceptance: Christ Jesus came into this world to save sinners.
God’s compassion for us is all the more wonderful because Christ died, not for the righteous or the holy but for the wicked and the sinful, and, though the divine nature could not be touched by the sting of death, he took to himself, through his birth as one of us, something he could offer on our behalf.
The power of his death once confronted our death. In the words of Hosea the prophet:Death, I shall be your death; grave, I shall swallow you up. By dying he submitted to the laws of the underworld; by rising again he destroyed them. He did away with the everlasting character of death so as to make death a thing of time, not of eternity. As all die in Adam, so all will be brought to life in Christ.
