Citing eye-witnesses who had nothing to gain by lying, and in fact risked their lives to testify that Jesus resurrected,Christians and the Christian Church have declared since the very first that Jesus really and absolutely died on that cross, but did not stay dead! Thirty-Six hours later, he was alive again, and he is still alive, with a real physical body, to this day. No human agency participated in his resurrection in any way. And, Christians say, he will remain alive forever.
Part of Rome’s genius was adoption and adaptation—the ability to absorb and assimilate all comers, repurposing them to serve Rome’s dominant vision as the great civilizer of the world, the great unifier giving everyone equal access to the same gods and guiding principles. The Emperor was the supreme symbol, the creator and maintainer of this unity—the “Saviour of mankind”, the “Son of God” (Jupiter, Zeus, Amon-Ra, Baal, whichever high deity was relevant to the people in question). Every subject and citizen of the Empire owed their final allegiance to the Emperor as the incarnation of Rome’s “genius”, or “Spirit-Guide”.
