They saw no man but Jesus only. When it is said that in the end they saw Christ alone, this means that the Law and the Prophets had a temporary glory, that Christ alone might remain fully in view. If we would properly avail ourselves of the aid of Moses, we must not stop with him, but must endeavor to be conducted by his hand to Christ, of whom both he and all the rest are ministers. This passage may also be applied to condemn the superstitions of those who confound Christ not only with prophets and apostles, but with saints of the lowest rank, in such a manner as to make him nothing more than one of their number. But when the saints of God are eminent in graces, it is for a totally different purpose than that they should defraud Christ of a part of his honor, and appropriate it to themselves. In the disciples themselves we may see the origin of the mistake; for so long as they were terrified by the majesty of God, their minds wandered in search of men, but when Christ gently raised them up, they saw him alone If we are made to experience that consolation by which Christ relieves us of our fears, all those foolish affections, which distract us on every hand, will vanish away.
And when they had lift up their eyes,.... And "looked round about", as Mark says, to see whether the same objects still continued, as Moses and Elias; and the bright cloud:
they saw no man; neither Moses nor Elias, who were both gone: signifying, that though the law and the prophets were till this time, they were now finished and completed, and the Mosaic economy was to be no more; as these men appeared no more after, nor will they till the second coming of Christ. And Mark has it, "they saw no man any more"; that is, these men any more, neither then, nor afterwards, "save Jesus only". Mark adds, "with themselves"; in the same form as before his transfiguration. Christ is the only Mediator, Saviour, and Redeemer; the only Prophet, Priest, and King; and who only is to be, and can be beheld as such; and who does, and will abide with his people; and helps, comforts, and saves them, when none else can. Luke observes, that "when the voice was past, Jesus was found alone"; which was so ordered, that it might be a clear case, that this voice was only concerning Christ, and not either Moses or Elias.
They saw no man, save Jesus only. When they rose from their prostration the glorious vision was gone.
