Cyril of Jerusalem

"Give us this day our superessential bread." Ordinary bread is not "superessential," but this holy bread is superessential in the sense of being ordained for the essence of the soul. Not of this bread is it said that it "passes into the stomach and is discharged into the drain." No, it is absorbed into your whole system to the benefit of both soul and body. By "this day" he means "daily," as in Paul's "while it is called 'today.' "
