John Chrysostom — as excerpted in the Catena Aurea on Luke 22:19-20

“(Hom. 46. in Joan.) Christ did this to bring us to a closer bond of friendship, and to betoken His love toward us, giving Himself to those who desire Him, not only to behold Him, but also to handle Him, to eat Him, to embrace Him with the fulness of their whole heart. Therefore as lions breathing fire do we depart from that table, rendered objects of terror to the devil.”
