A reading from the Acts of the Apostles.
Peter stood up in the midst of the sisters and brothers, a gathering of perhaps hundred and twenty. “Sisters and brothers,” he said, “the saying in Scripture uttered long ago by the Holy Spirit through the mouth of David was destined to be fulfilled in Judas, the one who guided those who arrested Jesus. He was one of our number and had been given a share in this ministry of ours.
As David wrote in the Book of Psalms,
Let his encampment be desolate;
may no one dwell on it
Let another take his office.
“It is necessary, therefore, that one of those who was of our company while Jesus moved among us, from the baptism of John until the day Jesus was taken up from us, should be named as witness with us to the Resurrection.” At that, they nominated two – Joseph called Barsabbas, who was also known as Justus, and Matthias. Then they prayed, “O God, you can read the hearts of people. Show us which of these two you have chosen to occupy this apostolic ministry, replacing Judas, who deserted the cause and went the way he was destined to go.” They then drew lots between the two. The choice fell to Matthias, who was added to the eleven apostles.
