John Chrysostom — as excerpted in the Catena Aurea on John 6:22-27

“(Hom. xliv. 1) Kindness and lenity are not always expedient. To the indolent or insensible disciple the spur must be applied; and this the Son of God does. For when the multitude comes with soft speeches, Rabbi, when earnest Thou hither? He shews them that He did not desire the honour that cometh from man, by the severity of His answer, which both exposes the motive on which they acted, and rebukes it. Jesus answered them and said, Verily, verily, I say unto you, Ye seek Me, not because ye saw the miracles, but because ye did eat of the loaves, and were filled.”
