John Chrysostom

Let them hear this, who like swine with no thought but of eating rise from the table drunk, when they should have given thanks, and closed with a hymn. Let them hear who will not tarry for the final prayer in the sacred mysteries; for the last prayer of the mysteries represents that hymn. He gave thanks before He delivered the holy mysteries to the disciples, that we also might give thanks; He sung a hymn after He had delivered them, that we also should do the like.
