Of the benefit of good works and mercy
In Isaiah: “Cry aloud,” says He, “and spare not; lift up your 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 You have not seen: we have humiliated our souls, and You have not known. For in the days of fasting are found your own wills; for either you torment those who are subjected to you, or you fast for strifes and judgments, or you strike your neighbours with fists.
For what do you fast unto me, that today your voice should be heard in clamour? This fast I have not chosen, save that a man should humble his soul. And if you shall bend your neck like a ring, and spread under you sackcloth and ashes, neither thus shall it be called an acceptable fast. Not such a fast have I chosen, says the Lord; but loose every knot of unrighteousness, let go the chokings of impotent engagements. Send away the harassed into rest, and scatter every unrighteous contract.
Break your bread to the hungry, and bring the houseless poor into your dwelling. If you see the naked, clothe him; and despise not them of your own seed in your house. Then shall your seasonable light break forth, and your garments shall quickly arise; and righteousness shall go before you: and the glory of God shall surround you. Then you shall cry out, and God shall hear you; while you are yet speaking, He shall say, Here I am.” Concerning this same thing in Job: “I have preserved the needy from the hand of the mighty; and I have helped the orphan, to whom there was no helper.
The mouth of the widow blessed me, since I was the eye of the blind; I was also the foot of the lame, and the father of the weak.” Of this same matter in Tobit: “And I said to Tobias, My son, go and bring whatever poor man you shall find out of our brethren, who still has God in mind with his whole heart. Bring him hither, and he shall eat my dinner together with me. Behold, I attend you, my son, until you come.” Also in the same place: “All the days of your life, my son, keep God in mind, and transgress not His precepts.
Do justice all the days of your life, and do not walk in the way of unrighteousness; because if you act truly, there will be respect of your works. Give alms of your substance, and turn not your face from any poor man. So shall it come to pass that the face of God shall not be turned away from you. Even as you have, my son, so do: if you have abundant substance, give the more alms therefrom; if you have little, communicate even of that little. And do not fear when you give alms: you lay up for yourself a good reward against the day of need; because alms delivers from death, and does not suffer to go into darkness.
Alms is a good office for all who do it in the sight of the most high God.” On this same subject in Solomon in Proverbs: “He that has pity on the poor lends unto the Lord.” Also in the same place: “He that gives to the poor shall never want; but he who turns away his eye shall be in much penury.” Also in the same place: “Sins are purged away by almsgiving and faith.” Again, in the same place: “If your enemy hunger, feed him; and if he thirst, give him to drink: for by doing this you shall scatter live coals upon his head.” Again, in the same place: “As water extinguishes fire, so almsgiving extinguishes sin.” In the same in Proverbs: “Say not, Go away, and return, tomorrow I will give; when you can do good immediately.
For you know not what may happen on the coming day.” Also in the same place: “He who stops his ears that he may not hear the weak, shall himself call upon God, and there shall be none to hear him.” Also in the same place: “He who has his conversation without reproach in righteousness, leaves blessed children.” In the same in Ecclesiasticus: “My son, if you have, do good by yourself, and present worthy offerings to God; remember that death delays not.” Also in the same place: “Shut up alms in the heart of the poor, and this will entreat for you from all evil.” Concerning this thing in the thirty-sixth Psalm, that mercy is beneficial also to one's posterity: “I have been young, and I have also grown old; and I have not seen the righteous forsaken, nor his seed begging their bread.
The whole day he is merciful, and lends; and his seed is in blessing.” Of this same thing in the fortieth Psalm: “Blessed is he who considers over the poor and needy: in the evil day God will deliver him.” Also in the cxith Psalm: “He has distributed, he has given to the poor; his righteousness shall remain from generation to generation.” Of this same thing in Hosea: “I desire mercy rather than sacrifice, and the knowledge of God more than whole burnt-offerings.” Of this same thing also in the Gospel according to Matthew: “Blessed are they who hunger and thirst after righteousness: for they shall be satisfied.” Also in the same place: “Blessed are the merciful: for they shall obtain mercy.” Also in the same place: “Lay up for yourselves treasures in heaven, where neither moth nor rust does corrupt, and where thieves do not dig through and steal: for where your treasure is, there will your heart be also.” Also in the same place: “The kingdom of heaven is like a merchantman seeking goodly pearls: and when he has found a precious pearl, he went away and sold all that he had, and bought it.” That even a small work is of advantage, also in the same place: “And whoever shall give to drink to one of the least of these a cup of cold water in the name of a disciple, verily I say unto you, His reward shall not perish.” That alms are to be denied to none, also in the same place: “Give to every one that asks you; and from him who would wish to borrow, be not turned away.” Also in the same place: “If you will enter into life, keep the commandments. He says, Which? Jesus says unto him, You shall not kill, You shall not commit adultery, You shall not bear false witness, Honour your father and mother: and, You shall love your neighbour as yourself. The young man says unto Him, All these things have I observed: what lack I yet? Jesus says unto him, If you will be perfect, go and sell all that you have, and give to the poor, and you shall have treasure in heaven; and come, follow me.” Also in the same place: “When the Son of man shall come in His majesty, and all the angels with Him, then He shall sit on the throne of His glory: and all nations shall be gathered together before Him; and He shall separate them one from another, even as a shepherd separates the sheep from the goats: and He shall place the sheep on the right hand, but the goats on the left hand. Then shall the King say unto them that are on His right hand, Come, you blessed of my Father, receive the kingdom prepared for you from the beginning of the world. For I was hungry, and you gave me to eat: I was thirsty, and you gave me to drink: I was a stranger, and you took me in: naked, and you clothed me: I was sick, and you visited me: I was in prison, and you came unto me. Then shall the righteous answer Him, and say, Lord, when saw we You a stranger, and took You in: naked, and clothed You? And when saw we You sick, and in prison, and came to You? And the King, answering, shall say unto them, Verily I say unto you, Inasmuch as you did it to one of the least of these my brethren, you did it unto me. Then shall He say unto them who are on His left hand, Depart from me, you cursed, into everlasting fire, which my Father has prepared for the devil and his angels: for I was hungry, and you gave me not to eat: I was thirsty, and you gave me not to drink: I was a stranger, and you took me not in: I was naked, and you clothed me not: sick, and in prison, and you visited me not. Then shall they also answer, and say, Lord, when saw we You hungry, or thirsty, or a stranger, or naked, or sick, or in prison, and did not minister unto You? And He shall answer them, Verily I say unto you, Inasmuch as you did it not to one of the least of these, you did it not unto me. And these shall go away into everlasting burning: but the righteous into life eternal.” Concerning this same matter in the Gospel according to Luke: “Sell your possessions, and give alms.” Also in the same place: “He who made that which is within, made that which is without also. But give alms, and, behold, all things are pure unto you.” Also in the same place: “Behold, the half of my substance I give to the poor; and if I have defrauded any one of anything, I restore him fourfold. And Jesus said unto him, that salvation has this day been wrought for this house, since he also is a son of Abraham.” Of this same thing also in the second Epistle to the Corinthians: “Let your abundance supply their want, that their abundance also may be the supplement of your want, that there may be equality: as it is written, He who had much had not excess; and he who had little had no lack.” Also in the same place: “He who sows sparingly shall reap also sparingly; and he who sows in blessing shall reap also of blessing. But let every one do as he has proposed in his heart: not as if sorrowfully, or of necessity: for God loves a cheerful giver.” Also in the same place: “As it is written, He has dispersed abroad; he has given to the poor: his righteousness remains for ever.” Likewise in the same place: “Now he who ministers seed to the sower, shall both supply bread to be eaten, and shall multiply your seed, and shall increase the growth of the fruits of your righteousness: that in all things you may be made rich.” Also in the same place: “The administration of this service has not only supplied that which is lacking to the saints, but has abounded by much giving of thanks unto God.” Of this same matter in the Epistle of John: “Whoso has this world's substance, and sees his brother desiring, and shuts up his bowels from him, how dwells the love of God in him?” Of this same thing in the Gospel according to Luke: “When you make a dinner or a supper, call not your friends, nor brethren, nor neighbours, nor the rich; lest haply they also invite you again, and a recompense be made you. But when you make a banquet, call the poor, the weak, the blind, and lame: and you shall be blessed; because they have not the means of rewarding you: but you I shall be recompensed in the resurrection of the I just.”
