The nature of the revelation which Jesus received is not contradicted by any historical record which states otherwise. There is no record of Jesus being presented with inscribed tablets as happened with Moses, for example, or of his receiving a series of revelations like Muhammad, blessings and peace be on all of them, with certain disciples being appointed to record these revelations as they occurred - but not any of Jesus' s own words - in order to ensure that the revelation was preserved exactly as it was revealed.
