“Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?”
John 14:5 — Greek Interlinear
Church Fathers on John 14:5
If the Jews, who wished to be separated from Christ, asked where He was going, much more would the disciples, who wished never to be separated from Him, be anxious to know it. So with much love, and, at the same time, fear, they proceed to ask: Thomas said to Him, Lord, we know not where you go; and how can we know the way?
Our Lord had said that they knew both, Thomas says that they knew neither. Our Lord cannot lie; they knew not that they did know. Our Lord proves that they did: Jesus said to Him, I am the way, the truth, and the life.
For He who is the way does not lead us into devious courses out of the way; nor does He who is the truth deceive us by falsehoods; not does He who is the life leave us in the darkness of death.
