"Now consider which is more excellent, the bread of angels (i.e., the manna) or the Flesh of Christ which is indeed the Body of life.
That manna was from heaven; this is from above the heavens. The former was from heaven, the latter from the Lord of the heavens; the former was subject to corruption if it was preserved for a second day, the latter foreign to all corruption so that whoever shall have piously tasted it will not be able to experience corruption. For the people of
water flowed from the rock; for you Blood flows from Christ. The water satisfied them for a while; Blood washes you for eternity." Israel
St. Ambrose, Epistola
