Sabbath Day Restored

We should not provide for the Sabbath a more liberal supply or a greater variety of food than for other days. Instead of this, the food should be more simple, and less should be eaten, in order that the mind may be clear and vigorous to comprehend spiritual things. A clogged stomach means a clogged brain. The most precious words may be heard and not appreciated, because the mind is confused by an improper diet. By overeating on the Sabbath, many do more than they think, to unfit themselves for receiving the benefit of its sacred opportunities.—The Ministry of Healing, 307, 1905 CD 137.1
