For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given,"If even a beast touches the mountain, it shall be stoned." Indeed, so terrifying was the sight that Moses said, "I tremble with fear." But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.

hebrews 12:18-24

Whether we 'spiritualize' our life or 'secularize' our religion, whether we invite men to a spiritual banquet or simply join them at the secular one, the real life of the world, for which we are told God gave his only-begotten Son, remains hopelessly beyond our religious grasp.

alexander schmemann, for the life of the world, ch.1.1, p.13

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.'
