Arnobius

“ Do the gods of heaven [3] live on these sacrifices, and must materials be supplied to maintain the union of their parts? And what man is there so ignorant of what a god is, certainly, as to think that they are maintained by any kind of nourishment, and that it is the food given to them [4] which causes them to live and endure throughout their endless immortality? ”

“ But if a god, as is said, has no body, and cannot be touched at all, how is it possible that that which has no body should be nourished by things pertaining to the body,—that what is mortal should support what is immortal, and assist and give vitality to that which it cannot touch? This reason for sacrifices is not valid, therefore, as it seems; nor can it be said by any one that sacrifices are kept up for this reason, that the deities are nourished by them, and supported by feeding on them. ”

“ For whatever is upheld by causes and things external to itself, must be mortal and on the way to destruction, when anything on which it lives begins to be wanting. Again, it is impossible to suppose that any one believes this, because we see that of these things which are brought to their altars, nothing is added to and reaches the substance of the deities ”
