There are four passages from the New Testament that speak of the Last Supper. The Last Supper is, according to Scripture, the Passover Supper, which was attended by Jesus and the twelve apostles. The Last Supper took place during the evening before Jesus was arrested and sentenced to death through the Way of the Cross. Jesus announced at the Supper that it was his last Passover before his death.
The Last Supper is the moment when the Eucharist, or Mass and the priesthood, was established. The Last Supper took place in the Cenacle. The Cenacle was in Zion, the first Church and mother of all the Churches. It is the highest point in ancient Jerusalem. The name referred to the Mount on which the Jerusalem Temple in the Old Testament was built, which meant a new beginning, i.e. building a new community of the Church of Jesus. The Cenacle - the hall on the Mount became the place where the Church was born during the Last Supper.
It is also the place where the apostles took refuge during the Passion of Jesus. Jesus was betrayed by one of his disciples, Judas, on the same night that the Last Supper took place. Then he was captured and brought before the Jewish religious court, which found him guilty of blasphemy. Then Jesus was handed over to the Roman governor Pontius Pilate, who sentenced him to death by crucifixion.
