The words of the Gospel we have just heard (cf. Jn 20:19-31) speak to us of a place, a disciple and a book.

The place is where the disciples gathered on the evening of Easter; we read only that its doors were closed (cf. v. 19). Eight days later, the disciples were once more gathered there, and the doors were still shut (cf. v. 26). Jesus enters, stands in their midst and brings them his peace, the Holy Spirit and the forgiveness of sins: in a word, God’s mercy. Behind those closed doors there resounds Jesus’ call to his followers: "As the Father has sent me, so I send you” (v. 21).
