But those who are in his body appropriately eat the body, in order that while he is on the journey, through the body of Christ alone he might be refreshed by his flesh and learn not to hunger for anything but Christ, to thirst for nothing but Christ, to taste nothing but Christ, to live by none other, nor to be anything other than the body of Christ.
-St. Paschasius Radbertus, 831 AD
