One of the Twelve, who was called Judas Iscariot, went to the chief priests and said, “What are you willing to give me if I hand him over to you?” They paid him thirty pieces of silver, and from that time on he looked for an opportunity to hand him over. (Mt 26:14-25)

The sadness of the betrayal by one of the Twelve touches the heart. Yet, the Lord knows all that we are capable of and still loves us without limits. We pray for all who have been betrayed, especially for the people of Ukraine.
