The Great Commentary of Cornelius à Lapide
Matthew 20:18
We go up. That is, because Jerusalem, and especially the temple were on Mount Sion. Again, we go up, in order to submit to the Cross, according to that saying, "I, if I be lifted up from the earth, &c." Again He says " we go up " to mark this stedfast purpose, as S. Chrysostom paraphrases, "Ye see how I go of My free will to death; when then ye shall see Me hung upon the Cross, think not that I am no more than man: for though to be able to die is human, yet to be willing to die is more than human."
Lastly, we go up, as if to our triumph on the citadel of Jerusalem and Calvary; for on the cross Christ triumphed over death, sin, the devil and hell; as the Apostle teaches, Colossians 2:15.
The Son of Man is betrayed, &c. "For," says Rabanus, "Judas betrayed the Lord to the Jews, and they delivered Him to the Gentiles, i.e., to Pilate and the Romans. To this end the Lord refused prosperity in this world, but chose rather to suffer affliction, that He might shew us who have fallen by delights through what bitterness we must needs return; whence it follows to mock, and to scourge, and to crucify." "The whole salvation of men," says S. Chrysostom, "rests on the death of Christ; wherefore there is nothing for which we are more bound to render thanks to God than for His death. He imparted the mystery of His death to His Apostles in secret, because the more precious treasure is ever committed to the more worthy vessels." And again, "when sorrow comes at a time we are looking for it, it is found lighter than it would have been had it come upon us suddenly."
To mock, and to scourge, and to crucify. These were the three principal parts of the passion of Christ.
And the third day He shall rise again. This is the honey of the resurrection in which is hidden the gall of the passion. Whence S. Augustine (De Civ. l. 18) says "In His passion He shews us how we ought to suffer for the truth; in His resurrection we ought to hope in the Trinity, whence He says 'and on the third day He shall rise again. '" And S. Chrysostom "This was said, that when they should see the sufferings, they should look for the resurrection." And S. Augustine adds the reason "For one death, that namely of the Saviour according to the body, was to us a salvation from two deaths, both of soul and body; and this one resurrection gained for us two resurrections."
Morally, Christ often repeats the mention of His passion, that He might commend His love to them, and they might love Him in return, and repay love for love, blood for blood, death for death. For the Cross of Christ is the furnace and fire of love. Wherefore S. Bernard (De Quad. Deb.) says "Thou owest to Jesus Christ thy whole life, because He laid down His life for thine, and endured bitter torments that thou mightest not endure eternal torments;" and in conclusion he says, "When therefore I have given Him all that I am, and all that I can, is it not like only a drop compared to a river, or a grain of sand to a heap?" And again he says (Tract. de dilig. Deo) "If I owe my whole self in return for my creation, what can I add now for my re-creation, and for my re-creation in such a manner? For it was more easy to create me than to re-create me. For He who created me at once and with a word only, in re-creating me spoke many words, and performed wonderful acts, and endured afflictions, and not only afflictions, but indignities: in His first work He gave me to myself, in His second He gave Himself to me; and when He gave Himself He restored me to myself. For my creation and for my re-creation I owe myself for myself, and that doubly. What shall I give to God for Himself? for even if I could repay myself 2 thousand times over, what am I compared with God?"
For the sake of Christ therefore we should not refuse to endure reproaches, crosses and flames; for to Him belongs our life and all that we are, for He Himself bought and redeemed us not with gold, but with the Divine price of His own blood. S. Leo (Serm. 8, de Pass.) says, "Thy cross, 0 Christ, is the fountain of all blessings, by which is given to them that believe strength out of weakness, glory out of reproach, life out of death."
Then came to Him the mother, &c. Then, when they had heard from Christ that His death was at hand, and after death His Resurrection, after which they expected the glorious kingdom of Christ; wherefore they lose no time in making a request that they may themselves obtain the chief place in it above the other Apostles.
The mother of Zebedee's children. By name Salome. See S. Mark 15:40., S. Matthew 27:56. S. Mark says that the petition came not from the mother but from the sons. The petition of the mother proceeded from the petition of the sons, so that the sons spoke by the mouth of their mother.
A certain thing; saying, as S. Mark has it, we would that Thou shouldst do for us whatsoever we shall desire, for they feared that if they expressed their desire for the first place Christ would at once refuse it. They wish therefore to bind Christ by a general petition, which if He granted He would be unable to refuse the particular petition. This is the manner of women. In the same way Bathsheba introduced her petition to Solomon to give Abishag to Adonijah in marriage, 1 Kings 2:21, Solomon consented; but afterwards when she made her request known he refused, saying, Ask for him the kingdom.
