Today’s Gospel narrative speaks about Judas’ betrayal and prediction of Peter’s denial. Betrayal, simply means, to hand over. “In the gospels many people “hand over” Jesus: the Sanhedrin hands him over to Pilate (Mk 15:1, 10; Mt 27:2, 18; Lk 24:20; Jn 18:30,35), Pilate hands him over to the will of the people (Lk 23:25; Jn 19:16) or to the soldiers for execution (Mk 15:15; Mt 27:26). However, the one who is par excellence the person who hands over Jesus is Judas Iscariot. He is branded in all four gospels with this characteristics, as if were his special trademark: 11 times in Mt, 6 times in Mk, 5 times in Lk, and 10 times in Jn. In all, Judas is 32 times presented as ‘the one who handed Jesus over’” (365 Days with the Lord 2003, Liturgical Biblical Diary, On Passion Sunday, St Pauls).
“Judas, ‘the man of Kerioth,’ one of the Twelve, waited on the high priests, probably while Jesus was engaged with the Greeks (Jn 12:20-50), and offered for sufficient remuneration to betray him into their hands. Judas was a disappointed man. He had attached himself to Jesus, believing him to be Messiah, and expecting, in accordance with the current conception of the Messianic Kingdom, a rich recompense when the Master should ascend the throne of his father David, and confer offices and honors upon his faithful followers.
The period of his discipleship had been a process of disillusionment, and latterly, when he perceived the inevitable issue, he has determined to abandon he deemed a sinking cause, and save what he might from the wreck. It may be also that he desired to be avenged an the Master who, as he deemed, had fooled him with a false hope. He therefore went to the high priests and asked what he would give him to betray Jesus into their hands. They leaped at the proposal and offered him thirty shekel. It was the price of a slave (cf. Ex 21:32). Impervious to contempt, he accepted their offer; and as though in haste to get rid of him, they paid him money on the spot” (Hastings J., DD, Ed., Dictionary of Christ and the Gospels, Edinburg: T. & T. Clark).
Jesus, aware of Judas’ design and anxious to eat the Passover with his disciples (Lk 22:15), “reclining with his disciples, made a startling revelation: ‘One of you shall betray me’ (Jn 13:2). Amid the consternation which ensued, Jesus secretly gave Judas his dismissal. The traitor left the room, and hastening to the high priests, summoned them to action.
Soon after, Jesus was “rejected by the elders and the chief priests and the scribes,” who handed him to the Gentiles to be mocked and scourged and crucified” (Mk 8:31; Mt 20:11; see cf. CCC 572).
Certainly, Judas’ betrayal contributes to the crucifixion and death of Jesus. But Judas is not the only the person responsible for his death. Pontius Pilate, the Sanhedrin, the Jews had their own share too. Behind the scene, all sinners were authors of Christ’ passion.
In her Magisterial teaching of the faith and in the witness of her saints, the Church has never forgotten that “sinners were the authors and the ministers of all the sufferings that the divine Redeemer endured” (Roman Catechism 1, 5, 11; cf. Heb 12:3). Taking into account the fact that our sins affect Christ himself (cf. Mt 25:45; Acts 9:4-5) the Church does not hesitate to impute to Christians the gravest responsibility for the torments inflicted upon Jesus, a responsibility with which they have all too often burdened the Jews alone:
We must regard as guilty all those who continue to relapse into their sins. Since our sins made the Lord Christ suffer the torment of the cross, those who plunge themselves into disorders and crimes crucify the Son of God anew in their hearts (for he is in them) and hold him up to contempt. And it can be seen that our crimes in this case is greater in us than in the Jews. As for them, according to the witness of the Apostle, “None of the rulers of this age understood this; for if they had, they would not have crucified the Lord of glory.” We, however, profess to know him. And when we deny him by our deeds, we in some way seem to lay violent hands on him (Roman Catechism 1, 5, 11; cf. Heb 6:6; 1 Cor 2:8).
Nor did demons crucify him; it is you who have crucified him and crucify him still, when you delight in your vices and sins (St. Francis of Assisi, Admon. 5, 3. ; CCC 598).
