Sumptuous eating is harmful to all without exception, but especially to the young. The natural reason for this is obvious. The natural warmth of the young person is enhanced when it receives the fatty matter of various foods. The heavy foods consumed draw out the heavy excretions of digestion in the stomach. These in turn are converted into substances and blood and eventually into fatty tissue. The abundance of food creates a fat body that is susceptible to the forceful temptations of one's sexuality.
Thus treated and exposed the poor body becomes a flaming fire, a Babylonian furnace. If the young body is a wild and untamed animal even when it lacks essential nourishment, imagine what it is like when it is well fed! All young people know this because they experience these passions on a daily basis. This is why St. Gregory the Theologian said: "Its own evil is sufficient for the body. Why add to the existing fire any additional fuel, or any more nourishment to the beast? It will only become more difficult to control and more violent (forceful) than the mind." Solomon too said: "It is not fitting for a fool to live in luxury" (Proverbs 19:10). In interpreting this passage, St. Basil considered the body of a young person to be "a fool." "What is more senseless than the body of a young person prone to easy temptations?" he asked.
Now if you cannot avoid these fatty foods completely, then set a discipline for yourself to eat only once a day, as many spiritual persons, hierarchs, and even worldly leaders do. In this manner the body is kept lighter and healthier and the mind is clearer and more capable of advancing upon divine thoughts. Even then, it is important not to overeat.
[THE THREE DEGREES OF EATING]
-- According to St. Gregory the Sinaite there are three degrees in eating: temperance, sufficiency, and satiety. Temperance is when someone wants to eat some more food but abstains, rising from the table still somewhat hungry. Sufficiency is when someone eats what is needed and sufficient for normal nourishment. Satiety is when someone eats more than enough and is more than satisfied. Now if you cannot keep the first two degrees and you proceed to the third, then, at least, do not become a glutton, remembering the words of the Lord: "Woe to you that are full now, for you shall hunger" (Luke 6:25).
Remember also that rich man who ate in this present life sumptuously every day, but who was deprived of the desired bosom of Abraham in the next life, simply because of this sumptuous eating. Remember how he longed to refresh his tongue with a drop of water. St. Basil not only did not forgive the young people who ate to satiety but also those who ate until satisfied; he preferred that all eat temperately. He said, "Nothing subdues and controls the body as does the practice of temperance. It is this temperance that serves as a control to those youthful passions and desires."
St. Gregory the Theologian has also noted in his poetry: "No satiety has brought forth prudent behavior; for it is in the nature of fire to consume matter. And a filled stomach expels refined thoughts; it is the tendency of opposites to oppose each other." Job, too, assuming that one could fall into sin through eating, offered sacrifice to God for his sons who were feasting among themselves. "And when the days of the feast had run their course, Job would send and sanctify them, and he would rise early in the morning and offer burnt offerings according to the number of them all; for Job said: "It may be that my sons have sinned, and cursed God in their hearts'" (Job 1:5-8).
In interpreting this passage Olympiodoros wrote: "We learn from this that we ought to avoid such feasts which can bring on sinfulness. We must also purify ourselves after they have been concluded, even if these are conducted for the sake of concord and brotherly love as in the case of the sons of Job."
Surely then, if the sons of Job were not at a feast but in prayer or some other spiritual activity, the devil would not have dared to destroy the house and them, as Origen interpreted the passage: "The devil was looking for an opportunity to destroy them. Had he found them reading, he would not have touched the house, having no reason to put them to death. Had he found them in prayer, he would not have had any power to do anything against them. But when he found an opportune time, he was powerful. What was the opportune time? It was the time of feasting and drinking." Do you see then, dear reader, how many evils are brought forth by luxurious foods and feasting in general?
[WHAT ONE MUST DO TO AVOID OVEREATING AND OTHER SINS OF THE TONGUE]
-- When eating and drinking, always remember the Psalm: "What profit is there in my blood, if I go down to the Pit?" (Psalms 30:9). St. Basil has advised that we recall this verse in order to help us avoid overeating and overdrinking, as he has interpreted it in the following manner:
"What is the need for robustness of flesh and an abundance of blood if their future is to be delivered over to the common corruption of the body? For this reason I constrain and deprive my body, otherwise my blood becomes so robust and overzealous that it makes my flesh to sin. Do not therefore flatter your body with sleep and baths and soft beds, but always recall the saying: "What profit is there for my blood if I go down to the Pit?" Why do you care for the lesser thing that will later become corrupt? Why do you bother to make yourself fat? Do you not know that the fatter you make your body so much heavier will be the soul's prison?"
In this sense of the mouth are also included all those sins which are enacted by the tongue: condemnation, slander, mocking, insults, unreasonable excommunications, curses, reprimands, obscene talk, and all the other idle and vain words. From all these we must guard ourselves as much as possible, for as you know, we must give an account for every vain and idle word, according to the Sacred Scriptures (Matthew 12:36). . . . END
