John Young

 "How it has come to pass, that of all men He alone has risen to spiritual perfection? What God did for piety and virtue on earth at one time and in one case, God certainly could have done at other times and in other cases. If Jesus was man only, God could have raised up, in successive ages, many such living examples of sanctified humanity as He was, to correct, instruct, and quicken the world. But He did not."

John Young in Christ of History
