Jn 13:21-33, 36-38
Handling betrayal: The gospel presents two people who are important to Holy Week: Judas and Peter. Both of them, are flawed, combining strengths and weaknesses.
Yet Judas has many opportunities of coming to his senses. Jesus does not deny him his companionship or take away his apostleship. Jesus admits the traitor to the fellowship of his disciples at the Last Supper and washes his feet. Jesus gives him his body to eat and his blood to drink. Even when Judas comes with his crew to seize him and kisses him, Jesus receives him calmly and gently. Since Jesus shows his great mercy in so many ways even toward Judas, there is no reason why, in this life, anyone should despair.
Peter is guilty of denial that is tantamount to betrayal. The difference between them? Peter has an attitude of trust and therefore surrender; ultimately, he gladly gives his life for Jesus. Judas, on the other hand, has an attitude of selfish distrust and therefore flees from Jesus; this results in his hanging himself in despair.
