On Fasting by St. Paisy of Neamt

The third virtue is fasting. Fasting I call the eating of a little bit once a day. Getting up from the table when one is still hungry, having his food, bread, and salt, and his drink-water, which the springs themselves bring forth. Behold the royal way of receiving food; that is, many have been saved by this path, so the Holy Fathers have said. To refrain from food for a day, or two days, three, four, five, or a week, a man cannot do always. But, so as every day to eat bread and drink, one can always do this; only, having eaten, one should be a little hungry, so that the body will be submissive to the spirit and capable of labors and sensitive to mental movements, and so the bodily passions will be conquered. Complete fasting cannot mortify the bodily passions as well as poor food mortifies them. Some fast for a time and then give themselves over to delicious foods, for many begin fasting beyond their strength and also other severe labors, and then they grow weak from the lack of measure and unevenness of this labor, and they seek tasty foods and repose for the strengthening of the body. To act in this way means to build and then again destroy, since the body through thinness from fasting is yearning for sweet things and seeks consolation, and the sweet foods ignite the passions. But if someone establishes for himself a definite measure as to how much poor food to eat in a day, he will receive great profit. However, concerning the quantity of food, one must establish a rule that it be as much as is necessary for the strengthening of oneself. Such a one can perform every kind of spiritual work. But if someone fasts beyond this, at another time he will give himself up to repose. Ascetic labor according to measure is priceless. For certain of the Great Fathers also took food in measure, and in everything they used it in its right time, and everything had measure—in ascetic labors, in bodily needs, in cell possessions, and in everything they used it in its right time, and everything according to a definite, moderate rule. Therefore, the Holy Fathers do not command one to begin to fast above one's power and to make oneself weak. Take as your rule to eat every day; thus one may refrain in a more firm way; but if one fasts more than this, how will he refrain later from eating to the full and overeating? In no way will he be able to. Such an immoderate beginning comes either from vainglory or lack of understanding, while continence is one of the virtues which aids in the subjugating of the flesh. Hunger and thirst are given to man for the purification of the body, for the preservation from unclean thoughts and lustful passions. Every day to eat poorly is a means to perfection, as certain ones have said, and one who eats every day at a definite hour in no way is lowered morally nor undergoes any harm of soul. Saint Theodore the Studite praises such ones in his instruction on the Friday of the first week of the Great Fast, where he cites in confirmation of his words the Holy God-bearing Fathers and the Lord Himself. Thus we also should act.

The Lord endured a lengthy fast, as did Moses and Elias, but only once. And certain other ones sometimes when entreating something from the Creator, laid upon themselves a certain time of fasting, but in accordance with natural laws and the teaching of the Divine Scripture. From the activity of the Saints, from the Life of our Savior, and from the rules of those who have lived in good order, it is evident that it is splendid and profitable always to be ready and to be found in ascetic labor, in work, and in endurance; however, not to weaken oneself by immoderate fasting and not to bring the body into a state of inactivity. If the flesh is inflamed because of youth, one must refrain a great deal; but if it is infirm, one must take much or little. Look and judge according to your own infirmity as to how much you can do. To each one there is a measure, and the inward teacher is one's conscience; not everyone can have the same rule and same ascetic labor, because some are strong and others are weak. Some are like iron, others are like copper, while others are like wax. And thus correctly discovering one's own measure, take food once each day, apart from Saturdays, Sundays, and Great Feasts of the Lord. A moderate and sensible fast is the foundation and chief of all virtues. One should fight evil as one fights a lion and a fierce serpent—in the infirmity of the body and spiritual poverty. He who wishes his mind to be firm against defiled thoughts should make his body refined through fasting.

It is not possible, without fasting, to serve as a Priest. As it is indispensible to breathe, so also is it to fast. Fasting once having entered into the soul, kills to the depths the sin which lies therein.
