Catena Aurea on Luke 22:14–18: John Chrysostom

Remember then when thou sittest down to meat that after the meal thou must pray; therefore satisfy thy hunger, but with moderation, lest being overcharged thou shouldest not be able to bend thy knees in supplication and prayer to God. Let us not then after our meals turn to sleep, but to prayer. For Christ plainly signifies this, that the partaking of food should not be followed by sleep or rest, but by prayer and reading the holy Scripture. It follows, For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God come.
