Isaias 58:7

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. …

“But I say unto you which hear” (displaying here that old injunction, of the Creator: “Speak to the ears of those who lend them to you”), “Love your enemies, and bless those which hate you, and pray for them which calumniate you.” These commands the Creator included in one precept by His prophet Isaiah: “Say, Ye are our brethren, to those who hate you.” For if they who are our enemies, and hate us, and speak evil of us, and calumniate us, are to be called our brethren, surely He did in effect bid us bless them that hate us, and pray for them who calumniate us, when He instructed us to reckon them as brethren. …

And now, on the subject of a loan, when He asks, “And if ye lend to them of whom ye hope to receive, what thank have ye?” compare with this the following words of Ezekiel, in which He says of the before-mentioned just man, “He hath not given his money upon usury, nor will he take any increase”, meaning the redundance of interest, which is usury. The first step was to eradicate the fruit of the money lent, the more easily to accustom a man to the loss, should it happen, of the money itself , the in terest of which he had learnt to lose. Now this, we affirm, was the function of the law as preparatory to the gospel. It was engaged in forming the faith of such as would learn, by gradual stages, for the perfect light of the Christian discipline, through the best precepts of which it was capable, inculcating a benevolence which as yet expressed itself but falteringly. …

What kind of persons does He bid should be invited to a dinner or a supper? Precisely such as he had pointed out by Isaiah: “Deal thy bread to the hungry man; and the beggars, even such as have no home, bring in to thine house,” because, no doubt, they are “unable to recompense” your act of humanity. Now, since Christ forbids the recompense to be expected now, but promises it “at the resurrection,” this is the very plan of the Creator, who dislikes those who love gifts and follow after reward. Consider also to which deity is better suited the parable of him who issued invitations: “A certain man made a great supper, and bade many.” The preparation for the supper is no doubt a figure of the abundant provision of eternal life. …

“Salvation comes to the house” of Zac chæus even. For what reason? Was it because he also believed that Christ came by Marcion? But the blind man’s cry was still sounding in the ears of all: “Jesus, Thou Son of David, have mercy on me.” And “all the people gave praise unto God”, not Marcion’s, but David’s. Now, although Zacchæus was probably a Gentile, he yet from his intercourse with Jews had obtained a smattering of their Scriptures, and, more than this, had, without knowing it, fulfilled the precepts of Isaiah: “Deal thy bread,” said the prophet, “to the hungry, and bring the poor that are cast out into thine house.” This he did in the best possible way, by receiving the Lord, and entertaining Him in his house. “When thou seest the naked cover him.” This he promised to do, in an equally satisfactory way, when he offered the half of his goods for all works of mercy. …

For, so far as pertains to fasts, they oppose to us the definite days appointed by God: as when, in Leviticus, the Lord enjoins upon Moses the tenth day of the seventh month (as) a day of atonement, saying, “Holy shall be to you the day, and ye shall vex your souls; and every soul which shall not have been vexed in that day shall be exterminated from his people.” At all events, in the Gospel they think that those days were definitely appointed for fasts in which “the Bridegroom was taken away;” and that these are now the only legitimate days for Christian fasts, the legal and prophetical antiquities having been abolished: for wherever it suits their wishes, they recognise what is the meaning of “the Law and the prophets until John.” Accordingly, (they think) that, with regard to the future, fasting was to be indifferently observed, by the New Discipline, of choice, not of command, accord …

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. …

The apostle in his first Epistle to Timothy: “But if any take not care of his own, and especially of those of his own household, he denies the faith, and is worse than an infidel.” Of this same thing in Isaiah: “If thou shalt see the naked, clothe him; and despise not those who are of the household of thine own seed.” Of which members of the household it is said in the Gospel: “If they have called the master of the house Beelzebub, how much rather them of his household!”
