It is this disciple who testifies to these things and has written them, and we know that his testimony is true. There are also many other things that Jesus did, but if these were to be described individually, I do not think the whole world would contain the books that would be written. (Jn 21:20-25)

We come to the second conclusion of the Fourth Gospel with the passage about the Beloved Disciple. We learn that the Beloved has written these things, and as the writer of this passage says, “We know that his testimony is true.” Obviously, the Beloved has died, but why would there be any doubt about whether this disciple would not die, unless the Beloved is truly Lazarus whom Jesus had raised from the dead? The Acts of the Apostles also comes to an end with Paul under house arrest in Rome freely preaching the gospel and fulfilling the words of Jesus: “You will be my witnesses . . . to the ends of the earth” (Acts 1:8). Tomorrow is Pentecost, the end of the Easter Season. Today we remember the Blessed Virgin Mary who remained in prayer with the early community of disciples.
These reflections are a result of more than 40 years of ministry as a Roman Catholic priest. Most of these years I spent in the Diocese of Charlotte which covers Western North Carolina. Now I am retired, and live in Medellín, Colombia where I continue to serve as a priest in the Archdiocese of Medellín.
