Church Fathers on Luke 22:21

When our Lord had given the cup to His disciples, He again spoke of His betrayer, saying, But, behold, the hand of him that betrays me, &c.

And this He said not only to show that He knew all things, but also to declare to us His own especial goodness, in that He left nothing undone of those things which belonged to Him to do; (for He gives us an example, that even to the end we should be employed in reclaiming sinners;) and moreover to point out the baseness of the traitor who blushed not to be His guest.

Yet though partaking of the mystery, he was not converted. Nay, his wickedness is made only the more awful, as well because under the pollution of such a design, he came to the mystery, as that coming he was not made better, either by fear, gratitude, or respect.
