1John 3:17 · Douay-Rheims
“He that hath the substance of this world, and shall see his brother in need, and shall shut up his bowels from him: how doth the charity of God abide in him?”

“But neither let the consideration, dearest brethren, restrain and recall the Christian from good and righteous works, that any one should fancy that he could be excused for the benefit of his children; since in spiritual expenditure we ought to think of Christ, who has declared that He receives them; and not prefer our fellow-servants, but the Lord, to our children, since He Himself instructs and warns us, saying, "He that loveth father or mother more than me is not worthy of me, and he that loveth son or daughter more than me is not worthy of me." Also in Deuteronomy, for the strengthening of faith and the love of God, similar things are written: "Who say," he saith, "unto their father or mother, I have not known thee; neither did they acknowledge their children, these have observed Thy words, and kept Thy covenant." For if we love God with our whole heart, we ought not to prefer either our parents or children to God. And this also John lays down in his epistle, that the love of God is not in them whom we see unwilling to labour for the poor. "Whoso," says he, "hath this world's goods, and seeth his brother have need, and shutteth up his bowels from him, how dwelleth the love of God in him?" For if by almsgiving to the poor we are lending to God-and when it is given to the least it is given to Christ-there is no ground for any one preferring earthly things to heavenly, nor for considering human things before divine.”

“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 hath this world's substance, and seeth his brother desiring, and shutteth up his bowels from him, how dwelleth the love of God in him? " Of this same thing in the Gospel according to Luke: "When thou makest a dinner or a supper, call not thy friends, nor brethren, nor neighbours, nor the rich; lest haply they also invite thee again, and a recompense be made thee. But when thou makest a banquet, call the poor, the weak, the blind, and lame: and thou shalt be blessed; because they have not the means of rewarding thee: but thou I shalt be recompensed in the resurrection of the I just."”

“When you see someone in need, do not run away, but think to yourself, if that were you, would you want to be treated like that?”

“But thou wilt say to me, And by what am I to know it? For to what it is perfected, we have heard; whence it begins, let us hear. He goes on to say: "But whoso hath this world's good, and seeth his brother have hunger, and shutteth up his bowels of compassion from him, how can the love of God dwell in him?" Lo, whence charity begins withal! If thou art not yet equal to the dying for thy brother, be thou even now equal to the giving of thy means to thy brother. Even now let charity smite thy bowels, that not of vainglory thou shouldest do it, but of the innermost marrow of mercy; that thou consider him, now in want. For if thy superfluities thou canst not give to thy brother, canst thou lay down thy life for thy brother? There lies thy money in thy bosom, which thieves may take from thee; and though thieves do not take it, by dying thou wilt leave it, even if it leave not thee while living: what wilt thou do with it? Thy brother hungers, he is in necessity: be-like he is in suspense, is distressed by his creditor: he is thy brother, alike ye are bought, one is the price paid for you, ye are both redeemed by the blood of Christ: see whether thou have mercy, if thou have this world's means.”

“Perchance thou sayest, "What concerns it me? Am I to give my money, that he may not suffer trouble?" If this be the answer thy heart makes to thee, the love of the Father abideth not in thee. If the love of the Father abide not in thee, thou art not born of God. How boastest thou to be a Christian? Thou hast the name, and hast not the deeds. But if the work shall follow the name, let any call thee pagan, show thou by deeds that thou art a Christian. For if by deeds thou dost not show thyself a Christian, all men may call thee a Christian yet; what doth the name profit thee where the thing is not forthcoming?”

Gregory the Great Patristic
c. A.D. 540–604
“But behold, no one persecutes us even unto death. How then can we prove whether we love our enemies? Yet there is something that ought to be done in the peace of holy Church, by which it may become clear whether we would be able to die for love in a time of persecution. Certainly the same John says: "He who has the substance of this world, and sees his brother in need, and closes his heart against him, how does the love of God remain in him?" Hence also John the Baptist says: "He who has two tunics, let him give to him who has none." Therefore, he who in a time of tranquility does not give his tunic for God, when will he give his life in persecution? Therefore, let the virtue of charity, that it may be unconquered in disturbance, be nourished through mercy in tranquility, so that one may first learn to spend one's possessions for almighty God, and afterward oneself.”

Bede Patristic
A.D. 673–735
“Whoever has the world's goods, and sees his brother in need, etc. Behold where love begins. If you are not yet fit to die for your brother, be at least fit to give from your possessions to your brother. For if you do not sympathize with your brother suffering hardship, indeed the love of the Father, from whom both of you were reborn, does not abide in you.”
