Isaias 58:2

And how Christ after He was born was to escape the notice of other men until He grew to man’s estate, which also came to pass, hear what was foretold regarding this. There are the following predictions: “Unto us a child is born, and unto us a young man is given, and the government shall be upon His shoulders;” which is significant of the power of the cross, for to it, when He was crucified, He applied His shoulders, as shall be more clearly made out in the ensuing discourse. And again the same prophet Isaiah, being inspired by the prophetic Spirit, said, “I have spread out my hands to a disobedient and gainsaying people, to those who walk in a way that is not good. …

“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. …

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. …
