Isaias 58:8

He says then to them again concerning these things, “Why do ye fast to Me as on this day, saith the Lord, that your voice should be heard with a cry? I have not chosen this fast, saith the Lord, that a man should humble his soul. Nor, though ye bend your neck like a ring, and put upon you sackcloth and ashes, will ye call it an acceptable fast.” To us He saith, “Behold, this is the fast that I have chosen, saith the Lord, not that a man should humble his soul, but that he should loose every band of iniquity, untie the fastenings of harsh agreements, restore to liberty them that are bruised, tear in pieces every unjust engagement, feed the hungry with thy bread, clothe the naked when thou seest him, bring the homeless into thy house, not despise the humble if thou behold him, and not [turn away] from the members of thine own family. …

“Learn, therefore, to keep the true fast of God, as Isaiah says, that you may please God. Isaiah has cried thus: ‘Shout vehemently, and do not spare: lift up thy voice as with a trumpet, and show My people their transgressions, and the house of Jacob their sins. They seek Me from day to day, and desire to know My ways, as a nation that did righteousness, and forsook not the judgment of God. They ask of Me now righteous judgment, and desire to draw near to God, saying, Wherefore have we fasted, and Thou seest not? and afflicted our souls, and Thou hast not known? Because in the days of your fasting you find your own pleasure, and oppress all those who are subject to you. Behold, ye fast for strifes and debates, and smite the humble with your fists. …

“For the Lord knoweth the way of the righteous, and the way of the ungodly shall perish.” “Follow, therefore, O son, the good way which I shall describe, lending to me attentive ears.” “And I will give to thee the treasures of darkness, hidden and unseen” by the nations, but seen by us. And the treasures of wisdom are unfailing, in admiration of which the apostle says, “O the depth of the riches and the wisdom!” And by one God are many treasures dispensed; some disclosed by the law, others by the prophets; some to the divine mouth, and others to the heptad of the spirit singing accordant. And the Lord being one, is the same Instructor by all these. …

We have also in the Scriptures robes mentioned as allegorizing the hope of the flesh. Thus in the Revelation of John it is said: “These are they which have not defiled their clothes with women,”, indicating, of course, virgins, and such as have become “eunuchs for the kingdom of heaven’s sake.” Therefore they shall be “clothed in white rai ment,” that is, in the bright beauty of the unwedded flesh. In the gospel even, “the wedding garment” may be regarded as the sanctity of the flesh. And so, when Isaiah tells us what sort of “fast the Lord hath chosen,” and subjoins a statement about the reward of good works, he says: “Then shall thy light break forth as the morning, and thy garments, shall speedily arise;” where he has no thought of cloaks or stuff gowns, but means the rising of the flesh, which he declared the resurrection of, after its fall in death. …

33. Those prayers quickly ascend to God which the merits of our labours urge upon God. Thus also Raphael the angel was a witness to the constant prayer and the constant good works of Tobias, saying, “It is honourable to reveal and confess the works of God. For when thou didst pray, and Sarah, I did bring the remembrance of your prayers before the holiness of God. And when thou didst bury the dead in simplicity, and because thou didst not delay to rise up and to leave thy dinner, but didst go out and cover the dead, I was sent to prove thee; and again God has sent me to heal thee, and Sarah thy daughter-in-law. …

4. Finally, beloved brethren, the divine admonition in the Scriptures, as well old as new, has never failed, has never been silent in urging God’s people always and everywhere to works of mercy; and in the strain and exhortation of the Holy Spirit, every one who is instructed into the hope of the heavenly kingdom is com manded to give alms. God commands and prescribes to Isaiah: “Cry,” says He, “with strength, and spare not. Lift up thy voice as a trumpet, and declare to my people their transgressions, and to the house of Jacob their sins.” And when He had commanded their sins to be charged upon them, and with the full force of His indignation had set forth their iniquities, and had said, that not even though they should use supplications, and prayers, and fastings, should they be able to make atonement for their sins; nor, if they were clothed in sackcloth and ashes, be able to soften G …

In Isaiah: “Cry aloud,” saith He, “and spare not; lift up thy voice like a trumpet; tell my people their sins, and the house of Jacob their wickednesses. They seek me from day to day, and desire to know my ways, as a people which did righteousness, and did not forsake the judgment of God. They ask of me now a righteous judgment, and desire to approach to God, saying, What! because we have fasted, and Thou hast not seen: we have humiliated our souls, and Thou hast not known. For in the days of fasting are found your own wills; for either ye torment those who are subjected to you, or ye fast for strifes and judgments, or ye strike your neighbours with fists. For what do you fast unto me, that to-day your voice should be heard in clamour? This fast I have not chosen, save that a man should humble his soul. …

22. Thus, O Lord, thus, I beseech Thee, let there arise, as Thou makest, as Thou givest joy and ability, let “truth spring out of the earth, and righteousness look down from heaven,” and let there be “lights in the firmament.” Let us break our bread to the hungry, and let us bring the houseless poor to our house. Let us clothe the naked, and despise not those of our own flesh. The which fruits having sprung forth from the earth, behold, because it is good; and let our temporary light burst forth; and let us, from this inferior fruit of action, possessing the delights of contemplation and of the Word of Life above, let us appear as lights in the world, clinging to the firmament of Thy Scripture. …

8. How, then, do we find the two precepts of love indicated in these two commands of the Lord? “Take up thy bed,” saith He, “and walk.” What the two precepts are, my brethren, recollect with me. For they ought to be thoroughly familiar to you, and not merely to come into your mind when they are recited by us, but they ought never to be blotted out from your hearts. Let it ever be your supreme thought, that you must love God and your neighbor: “God with all thy heart, and with all thy soul, and with all thy mind; and thy neighbor as thyself.” These must always be pondered, meditated, retained, practised, and fulfilled. The love of God comes first in the order of enjoying; but in the order of doing, the love of our neighbor comes first. For He who commanded thee this love in two precepts did not charge thee to love thy neighbor first, and then God, but first God, afterwards thy neighbor. …

There is nothing better than oil. It is the cause of light, and there also it is the cause of light. “Then shall thy light break forth as the morning” ( Isa. lviii. 8 .), saith the Prophet, if thou showest pity upon thy neighbour. And as natural oil contains light, so then doth mercy [alms] grant us a great, a marvelous light. Much mention doth Paul, too, make of this mercy. In one place, hear him say, “Only that we should remember the poor.” ( Gal. ii. 10 .) And in another, “If it be meet for me to go also.” ( 1 Cor. xvi. 4 .) And in every place, turn where you will, ye see him anxious about this very thing. And again, “And let our people also learn to maintain good works.” ( Tit. iii. 14 .) And again, “These things are good and profitable unto men.” ( Tit. iii. 8 .) Listen to a certain other one who saith, “Alms do deliver from death” ( Tob. xii. …

And so that it is a thing indifferent is very clearly shown from this also; viz., because as it brings justification when observed, so it does not bring condemnation when it is broken in upon; unless perhaps the transgression of a command rather than the partaking of food brings punishment. But in the case of a thing that is good in its own nature, no time should be without it, in such a way as that a man may do without it, for if it ceases, the man who is careless about it is sure to fall into mischief. Nor again is any time given for what is bad in its own nature, because what is hurtful cannot help hurting, if it is indulged in, nor can it ever be made of a praiseworthy character. …
