The Resurrection of Jesus from the dead is the be-all and the end-all of the Christian faith. If Jesus didn’t rise from the dead, all bishops, priests, and Christian ministers should go home and get honest jobs, and all the Christian faithful should leave their churches immediately.
As Paul himself put it: “If Jesus is not raised from the dead, our preaching is in vain and we are the most pitiable of men.” It’s no good, of course, trying to explain the Resurrection away or rationalize it as a myth, a symbol, or an inner subjective experience. None of that does justice to the novelty and sheer strangeness of the Biblical message.
