The source of the following excerpts is Source: The Sermons of St. Francis de Sales for Lent. This is a re-post from a previous year, but St. Francis de Sales, the patron saint of the Diocese of Baker, is always timely!
In this excerpt, the saint speaks of the conditions which render fasting good and meritorious.
FASTING
To treat of fasting and of what is required to fast well, we must, at the start, understand that of itself fasting is not a virtue. The good and the bad, as well as Christians and pagans, observe it. The ancient philosophers observed it and recommended it. They were not virtuous for that reason, nor did they practice virtue in fasting. Oh, no, fasting is a virtue only when it is accompanied by conditions which render it pleasing to God. Thus it happens that it profits some and not others, because it is not undertaken by all in the same manner.
We find some people who think that to fast well during the holy season of Lent it is enough to abstain from eating some prohibited food. But this thought is too gross to enter into the hearts of religious, for it is to you I speak, as well as persons dedicated to Our Lord. We know very well that it is not enough to fast exteriorly if we do not also fast interiorly and if we do not accompany the fast of the body with that of the spirit.
That is why our Divine Master, who instituted the fast, greatly desired in His Sermon on the Mount to teach His Apostles how it must be practiced [Matt. 6:16-18], which is a matter of great profit and utility (for it would not have been becoming to the greatness and majesty of God to teach a useless doctrine. That could not be.). He knew that to draw strength and efficacy from fasting, something more than abstinence from prohibited food is necessary. Thus He instructed them and, consequently, disposed them to gather the fruits proper to fasting. Among many others are these four: fasting fortifies the spirit, mortifying the flesh and its sensuality; it raises the spirit to God; it fights concupiscence and gives power to conquer and deaden its passions; in short, it disposes the heart to seek to please only God with great purity of heart.
It will be very helpful to state clearly what must be done to fast well these forty days…Now, among all the conditions required for fasting well, I will select three principal ones and speak familiarly about them.
The first condition is that we must fast with our whole heart, that is to say, willingly, whole-heartedly, universally and entirely.
[St. Bernard] says that fasting was instituted by Our Lord as a remedy for our mouth, for our gourmandizing and for our gluttony. Since sin entered the world through the mouth, the mouth must do penance by being deprived of foods prohibited and forbidden by the Church, abstaining from them for the space of forty days. But this glorious saint adds that, as it is not our mouth alone which has sinned, but also all our other senses, our fast must be general and entire, that is, all the members of our body must fast. For if we have offended God through the eyes, through the ears, through the tongue, and through our other senses, why should we not make them fast as well? And not only must we make the bodily senses fast, but also the soul's powers and passions -- yes, even the understanding, the memory, and the will, since we have sinned through both body and spirit.
How many sins have entered into the soul through the eyes, as Holy Scripture indicates? [1 In. 2:16]. That is why they must fast by keeping them lowered and not permitting them to look upon frivolous and unlawful objects; the ears, by depriving them of listening to vain talk which serves only to fill the mind with worldly images; the tongue, in not speaking idle words and those which savor of the world or the things of the world. We ought also to cut off useless thoughts, as well as vain memories and superfluous appetites and desires of our will. In short, we ought to hold in check all those things which keep us from loving or tending to the Sovereign Good. In this way interior fasting accompanies exterior fasting.
This is what the Church wishes to signify during this holy time of Lent, teaching us to make our eyes, our ears and our tongue fast. For this reason she omits all harmonious chants in order to mortify the hearing; she no longer says Alleluia, and clothes herself completely in somber and dark colors. And on this first day she addresses us in these words: Remember, man, that you are dust, and to dust you shall return [Gen. 3:19], as if she meant to say: "Oh man, quit at this moment all joys and merrymaking, all joyful and pleasant reflections, and fill your memory with bitter, hard and sorrowful thoughts. In this way you will make your mind fast together with your body."
This is also what the Christians of the primitive Church taught us when, in order to spend Lent in a better way, they deprived themselves at this time of ordinary conversations with their friends, and withdrew into great solitude and places removed from communication with people. For the same reason, the ancient Fathers and the Christians of the year 400 or so were so careful to spend these forty days well that they were not satisfied with abstaining from prohibited meats, but even abstained from eggs, fish, milk and butter, and lived on herbs and roots alone. And not content with making their bodies fast in this manner, they made their minds and all the powers of the soul fast also. They placed sackcloth on their heads in order to learn to keep their eyes lowered. They sprinkled ashes on their heads as a sign of penitence. They withdrew into solitude to mortify the tongue and hearing, neither speaking nor hearing anything vain and useless. At that time they practiced great and austere penances by which they subjected their body and made all its members fast. They did all this with full liberty, neither forced nor constrained. Note how their fast was accomplished whole-heartedly and universally; for they understood very well that since not only the mouth has sinned, but also all the other senses of our bodies and powers of our soul, the passions and appetites are full of iniquities. It is thus reasonable that, in order to make our fast complete and meritorious, it should be universal, which is to say, practiced in both body and spirit. This is the first condition to be observed in order to fast well.
