Origen

“ We indeed also maintain with regard not only to the fruits of the earth, but to every flowing stream and every breath of air that the ground brings forth those things which are said to grow up naturally,—that the water springs in fountains, and refreshes the earth with running streams,—that the air is kept pure, and supports the life of those who breathe it, only in consequence of the agency and control of certain beings whom we may call invisible husbandmen and guardians; but we deny that those invisible agents are demons. ”

“ For those who through all their afflictions preserve their piety pure and unimpaired, show their true character to all spectators, whether visible or invisible, who behold them; while those who are otherwise minded, yet conceal their wickedness, when they have their true character exposed by misfortunes, become manifest to themselves as well as to those whom we may also call spectators. ”

“ In our opinion, a man can only be said to eat and drink with demons when he eats the flesh of what are called sacred victims, and when he drinks the wine poured out to the honour of the demons. But Celsus thinks that we cannot eat bread or drink wine in any way whatever, or taste fruits, or even take a draught of water, without eating and drinking with demons. He adds also, that the air which we breathe is received from demons, and that not an animal can breathe without receiving the air from the demons who are set over the air. ”
