Today, the subject of ‘Immortality’ is never raised in respectable circles especially so in the West [‘Can’t we stick to Football and the Sitcoms?.’]
The subject of ‘Immortality’ is in fact at the very heart of the Christian West.
Apostolic authority from Deacon to Pope has its legitimizing root in one event. The event of Jesus rising from the grave not just in spirit, but ‘In Flesh and Blood’, his meeting with the apostles, and his choosing of Peter as the first Pope, the rock [Petra] on which the Church was to be built. Christianity as we know it begins here.
Jesus’ ‘Resurrection in Eternal Life’ as testified to by the apostles was the Miracle that begat the formal Church. In the much cited line from Romans: ‘If you believe in your heart that God raised him from the dead, you will be saved‘.
The Resurrection of Jesus in ‘Flesh and Blood’ was the affirming seal that legitimized the new apostolic Church. If you question the apostles and their authority the entire spool unwinds [and Magus and Mark and Mary Magdalene did some serious unwinding ].
When you kneel at the pew, you kneel to this, the central Christian affirmation of Salvation in Christ. Rebirth [Re-natus] into Eternal Life.
