Self-restraint Leads to Higher Enjoyments
When the Saviour would instruct His disciples about the Advent of God's Kingdom and the end of the world's times, and teach His whole Church, in the person of the Apostles, He said, Take heed lest haply your hearts be overcharged with surfeiting and drunkenness, and care of this life (Luke 21:34).
And assuredly, dearly beloved, we acknowledge that this precept applies more especially to us, to whom undoubtedly the day denounced is near, even though hidden. For the advent of which it behooves every man to prepare himself, lest it find him given over to gluttony, or entangled in cares of this life. For by daily experience, beloved, it is proved that the mind's edge is blunted by over-indulgence of the flesh, and the heart's vigour is dulled by excess of food, so that the delights of eating are even opposed to the health of the body, unless reasonable moderation withstand the temptation and the consideration of future discomfort keep from the pleasure. For although the flesh desires nothing without the soul, and receives its sensations from the same source as it receives its motions also, yet it is the function of the same soul to deny certain things to the body which is subject to it, and by its inner judgment to restrain the outer parts from things unseasonable, in order that it may be the oftener free from bodily lusts, and have leisure for Divine wisdom in the palace of the mind, where, away from all the noise of earthly cares, it may in silence enjoy holy meditations and eternal delights. And, although this is difficult to maintain in this life, yet the attempt can frequently be renewed, in order that we may the oftener and longer be occupied with spiritual rather than fleshly cares; and by our spending ever greater portions of our time on higher cares, even our temporal actions may end in gaining the incorruptible riches.
Thus fasting in mind as well as body, and giving alms freely, we shall win God's highest favour
Let us remember that we owe love first to God, secondly to our neighbour, and that all our affections must be so regulated as not to draw us away from the worship of God, or the benefiting our fellow slave. But how shall we worship God unless that which is pleasing to Him is also pleasing to us? For, if our will is His will, our weakness will receive strength from Him, from Whom the very will came; for it is God, as the Apostle says, who works in us both to will and to do for (His) good pleasure (Philippians 2:13).
And so a man will not be puffed up with pride, nor crushed with despair, if he uses the gifts which God gave to His glory, and withholds his inclinations from those things, which he knows will harm him. For in abstaining from malicious envy, from luxurious and dissolute living, from the perturbations of anger, from the lust after vengeance, he will be made pure and holy by true fasting, and will be fed upon the pleasures of incorruptible delights, and so he will know how, by the spiritual use of his earthly riches, to transform them into heavenly treasures, not by hoarding up for himself what he has received, but by gaining a hundred-fold on what he gives. And hence we warn you, beloved, in fatherly affection, to make this winter fast fruitful to yourselves by bounteous alms, rejoicing that by you the Lord feeds and clothes His poor, to whom assuredly He could have given the possessions which He has bestowed on you, had He not in His unspeakable mercy wished to justify them for their patient labour, and you for your works of love.
Let us therefore fast on Wednesday and Friday, and on Saturday keep vigil with the most blessed Apostle Peter, and he will deign to assist with his own prayers our supplications and fastings and alms which our Lord Jesus Christ presents, Who with the Father and the Holy Ghost lives and reigns for ever and ever. Amen.
