(8) The Lord confirms by a sign the declaration that he is the Light of the world, by giving eyesight as well as light. That which had been proclaimed as a great truth of his Being and mission, viz. that he was the Light of the world, was now to be established and confirmed to the disciples by a signal miracle.
The "higher criticism" finds explanation of this and other similar miracles at Bethsaida and Jericho, in the prophecy of Isaiah 42:19; Isaiah 43:8; Isaiah 35:5; Isaiah 29:18. Volkmar holds that the story of Zacchaeus is thus rewritten!
Thoma thinks that we have a spiritualization of the "miracle" on Saul of Tarsus. It would be waste time to point out the differences which are patent to the simplest criticism.
