Recalling his own Holy Land pilgrimage experience, Monsignor Peter Vaghi explores three significant events in the life of the early Church that can be traced back to the Upper Room in Jerusalem: the Last Supper and the institution of the Eucharist, the post-resurrection appearances of Christ to his followers, and the Holy Spirit descending on the apostles at Pentecost. In writing about the Upper Room, Monsignor Vaghi tells of not just its historical significance, but its profound spiritual meaning, guiding us to a deeper appreciation and understanding of living the Christian life in prayer, worship and service.
