<P> The word is a derivative of the Latin word cēnō, which means "I dine". The Gospel of Mark employs the Ancient Greek: ἀνάγαιον, anagaion, (Mark 14: 15), whereas the Acts of the Apostles uses Ancient Greek: ὑπερῷον, hyperōion (Acts 1: 13), both with the meaning "upper room". The language in Acts suggests that the apostles used the Upper Room as a temporary residence (Ancient Greek: οὗ ἦσαν καταμένοντες, hou ēsan katamenontes), although the Jamieson - Fausset - Brown Bible Commentary disagrees, preferring to see the room as a place where they were "not lodged, but had for their place of rendezvous". </P> <P> Jerome used the Latin coenaculum for both Greek words in his Latin Vulgate translation . In Christian tradition, the "Upper Room" was not only the site of the Last Supper (i.e. the Cenacle), but the room in which the Holy Spirit alighted upon the eleven apostles after Easter . It is sometimes thought to be the place where the apostles stayed in Jerusalem and, according to the Catholic Encyclopedia, it was "the first Christian church". </P> <P> The Cenacle is considered the site where many other events described in the New Testament took place, such as: </P> <Ul> <Li> preparation for the celebration of Jesus' final Passover meal </Li> <Li> the washing of his disciples' feet </Li> <Li> certain resurrection appearances of Jesus </Li> <Li> the gathering of the disciples after the Ascension of Jesus </Li> <Li> the election of Saint Matthias as apostle </Li> <Li> the descent of the Holy Ghost upon the disciples on the day of Pentecost . </Li> </Ul>
