Origen,
Ante-Nicene Fathers Vol. IX, Origen on Matthew…
(1885)
“ As then in the case of more common foods it is the practice at one time only to taste them, and at another to eat of them more largely; so also, in the case of these loaves, one eats insufficiently only tasting them, but another is satiated,—he that is good or is on the way to being good with the living bread which came down from heaven, but he that is wicked with the dead bread, which is death; and some perhaps sparingly, and sinning a little, only taste of death; but those who have attained to virtue do not even taste of it, but are always fed on the living bread. ”
