Considering the place which our Lord's risen body had in Paul's conversion, it could not be otherwise. At the very moment when Paul's whole system of thought was in a state of fusion the risen Lord was pre-eminently impressed upon it. It was through his conviction of the resurrection of Christ that both Paul's theology and his character were once for all radically altered. The idea of a crucified Messiah had been abhorrent to him, and his life was dedicated to the extirpation of this vile heresy that sprang from the Cross. But from the moment when with his own eyes he saw the risen Lord he understood, with the rest of the disciples, that death was the Messiah's appointed path to supreme spiritual headship. As truly in Paul's case as in that of the other disciples faith sprang from the sight of the glorified Christ; and to none could it be so inevitable as to him to say, "If Christ be not risen, then is our preaching vain, and your faith is also vain." From the first Paul had put the resurrection of Christ forward as an essential and fundamental part of the Gospel he had received, and which he was accustomed to deliver. And, generally speaking, this place is assigned to it both by believers and by unbelievers. It is recognised that it was the belief in the Resurrection which first revived the hopes of Christ's followers and drew them together to wait for the promise of His Spirit. It is recognised that whether the Resurrection be a fact or no, the Church of Christ was founded on the belief that it had taken place, so that if that had been removed the Church could not have been. This is affirmed as decisively by unbelievers as by believers. The great leader of modern unbelief (Strauss) declares that the Resurrection is "the centre of the centre, the real heart of Christianity as it has been until now;" while one of his ablest opponents says, "The Resurrection created the Church, the risen Christ made Christianity; and even now the Christian faith stands or falls with Him.... If it be true that no living Christ ever issued from the tomb of Joseph, then that tomb becomes the grave, not of a man, but of a religion, with all the hopes built on it and all the splendid enthusiasms it has inspired" (Fairbairn). It is not difficult to perceive what it was in the resurrection of Christ which gave it this importance.
