Church Fathers on Luke 24:41

The Lord had shown His disciples His hands and His feet, that He might certify to them that the same body which had suffered rose again. But to confirm them still more, He asked for something to eat.

By the command of the law indeed the Passover was eaten with bitter herbs, because the bitterness of bondage still remained, but after the resurrection the food is sweetened with a honeycomb; as it follows, And they gave him a piece of a broiled fish, and a honeycomb.

To convey therefore the truth of His resurrection, He condescends not only to be touched by His disciples, but to eat with them, that they might not suspect that His appearance was not actual, but only imaginary. Hence it follows, And when he had eaten before them, he took the remnant, and gave to them. He ate indeed by His power, not from necessity. The thirsty earth absorbs water in one way, the burning sun in another way, the one from want, the other from power.
