Today, we hear Christ telling the apostles at the Last Supper that He will be glorified. This is stated clearly after Christ shows that Judas will betray Him.
Two mysterious things happen almost simultaneously. Satan enters Judas because Judas has given himself over to Satan in order to betray Christ. He is now possessed, by willingly giving over his free will, his decision of treachery to the dark side of evil. Those of us who have been betrayed by loved ones or trusted friends join with Christ in His suffering.
It is as if Satan and Judas have made a pact--Christ's death for Judas' soul. Judas cooperates with Evil to bring down Christ, the Son of God. But, Satan does not see the end of the story.
The second mysterious occurrence is announced by Christ in these words said after Judas leaves:
When he therefore was gone out, Jesus said: Now is the Son of man glorified, and God is glorified in him.
32 If God be glorified in him, God also will glorify him in himself; and immediately will he glorify him.
Christ speaks of His glory, and that the Father is glorified because of Him, Christ. God gives the glory back to Christ in line 32, as the Father and the Son are One.
What is this glory? I think the glory is threefold.
First of all, the sacrifice of Christ on the Cross, the Passion, begins in this Upper Room with the Institution of the Eucharist and the priesthood.
Christ and the Father are glorified both in the Mass and in the priesthood. The apostles become each an alter Christus, the other Christs, bringing the Body and Blood of Christ to all Catholics down to this present day through the apostolic succession. Indeed, these two new rites, new sacraments, Holy Eucharist and Holy Orders, bring glory to God, to Christ, to the Church.
Second, Christ is glorified, and therefore, glorifies the Father through His perfect obedient Passion and Death on the Cross, which is the New Passover, the freeing of all mankind from the bondage of eternal death and sin. Christ is the Second Adam, undoing the sin of Adam through suffering as the Lamb of God Who takes away the sins of the world. God is glorified in His Son's redemption of all people. Freedom to be saints, to regain the lost innocence of Adam and Eve is given to all. The New Passover Lamb leads the New People of God through the new Red Sea of baptism, earned on the Cross by Christ. Christ is the New Adam, the New Moses, the New King David.
Third, Christ is glorified in His love for both the Father and all mankind, and this Love is the Third Person of the Blessed Trinity, the Holy Ghost. The Trinity is glorified at this Last Supper, in Gethsemane, on Calvary, and finally, as shown to all the world, at the Resurrection.
So, now is the Son glorified...
John 13:
18 I speak not of you all: I know whom I have chosen. But that the scripture may be fulfilled: He that eateth bread with me, shall lift up his heel against me.
19 At present I tell you, before it come to pass: that when it shall come to pass, you may believe that I am he.
20 Amen, amen I say to you, he that receiveth whomsoever I send, receiveth me; and he that receiveth me, receiveth him that sent me.
21 When Jesus had said these things, he was troubled in spirit; and he testified, and said: Amen, amen I say to you, one of you shall betray me.
22 The disciples therefore looked one upon another, doubting of whom he spoke.
23 Now there was leaning on Jesus' bosom one of his disciples, whom Jesus loved.
24 Simon Peter therefore beckoned to him, and said to him: Who is it of whom he speaketh?
25 He therefore, leaning on the breast of Jesus, saith to him: Lord, who is it?
26 Jesus answered: He it is to whom I shall reach bread dipped. And when he had dipped the bread, he gave it to Judas Iscariot, the son of Simon.
27 And after the morsel, Satan entered into him. And Jesus said to him: That which thou dost, do quickly.
28 Now no man at the table knew to what purpose he said this unto him.
29 For some thought, because Judas had the purse, that Jesus had said to him: Buy those things which we have need of for the festival day: or that he should give something to the poor.
30 He therefore having received the morsel, went out immediately. And it was night.
31 When he therefore was gone out, Jesus said: Now is the Son of man glorified, and God is glorified in him.
32 If God be glorified in him, God also will glorify him in himself; and immediately will he glorify him.
