Man must eat in order to live; he must take the world into his body and transform it into himself, into flesh and blood. He is indeed that which he eats, and the whole world is presented as one all-embracing banquet table for man. And this image of the banquet remains, throughout the whole Bible, the central image of life. It is the image of life at its creation and also the image of life at its end and fulfillment: 'that you eat and drink at my table in my Kingdom.'

alexander schmemann, for the life of the world, ch.1.1, p.11
