Clement of Alexandria

Nor is it suitable to eat and to drink simultaneously. For it is the very extreme of intemperance to confound the times whose uses are discordant. And "whether ye eat or drink, do all to the glory of God," aiming after true frugality, which the Lord also seems to me to have hinted at when He blessed the loaves and the cooked fishes with which He feasted the disciples, introducing a beautiful example of simple food.
