All the believers were together and had everything in common. Selling their possessions and goods, they gave to anyone as he had need. Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved. Acts 2:44-46

All the believers were one in heart and mind. No one claimed that any of his possessions was his own, but they shared everything they had. With great power the apostles continued to testify to the resurrection of the Lord Jesus, and much grace was upon them all. There were no needy persons among them. For from time to time those who owned lands or houses sold them, brought the money from the sales and put it at the apostles feet, and it was distributed to anyone as he had need. Acts4:32-35

You shall communicate in all things with your neighbor; you shall not call things your own; for if you are partakers in common of things which are incorruptible, how much more [should you be] of those things which are corruptible! Barnabas (A.D. 70-130) ch.19

Do not turn away from him who is in want; rather, share all things with your brother, and do not say that they are your own. For if you are partakers in that which is immortal, how much more in things which are mortal? Didache (A.D. 80-140) ch.4

Toil together one with another, struggle together, run together, suffer together, lie down together, rise up together, as God’s stewards and assessors and ministers. Ignatius: to Polycarp (A.D. 35-105) ch.6

For the Christians are distinguished from other men neither by country, nor language, nor the customs which they observe. For they neither inhabit cities of their own, nor employ a peculiar form of speech, nor lead a life which is marked out by any singularity. The course of conduct which they follow has not been devised by any speculation or deliberation of inquisitive men; nor do they, like some, proclaim themselves the advocates of any merely human doctrines. But, inhabiting Greek as well as barbarian cities, according as the lot of each of them has determined, and following the customs of the natives in respect to clothing, food, and the rest of their ordinary conduct, they display to us their wonderful and confessedly striking method of life. They dwell in their own countries, but simply as sojourners. As citizens, they share in all things with others, and yet endure all things as if foreigners. Every foreign land is to them as their native country, and every land of their birth as a land of strangers. They marry, as do all [others]; they beget children; but they do not destroy their offspring. They have a common table, but not a common bed. They are in the flesh, but they do not live after the flesh. They pass their days on earth, but they are citizens of heaven. They obey the prescribed laws, and at the same time surpass the laws by their lives. They love all men, and are persecuted by all. They are unknown and condemned; they are put to death, and restored to life. They are poor, yet make many rich; they are in lack of all things, and yet abound in all; they are dishonoured, and yet in their very dishonour are glorified. They are evil spoken of, and yet are justified; they are reviled, and bless; they are insulted, and repay the insult with honour; they do good, yet are punished as evil-doers. When punished, they rejoice as if quickened into life; they are assailed by the Jews as foreigners, and are persecuted by the Greeks; yet those who hate them are unable to assign any reason for their hatred. Letter to Diognetus (A.D. 125-200) ch.5

But whosoever takes upon himself the burden of his neighbor, whosoever desires to benefit one that is worse off in that in which he himself is superior, whosoever by supplying to those that are in want possessions which he received from God becomes a God to those who receive them from him, he is an imitator of God. Letter to Diognetus (A.D. 125-200) ch. 10

Have regard one to another, and assist one another, and do not partake of the creatures of God alone in abundance, but share them also with those that are in want. For some men through their much eating bring weakness on the flesh, and injure their flesh: whereas the flesh of those who have naught to eat is injured by their not having sufficient nourishment, and their body is ruined. This exclusiveness therefore is hurtful to you that have and do not share with them that are in want. Hermas (A.D. 150) Ante-Nicene Fathers vol.2 pg. 16

The rich man has much wealth, but in the things of the Lord he is poor, being distracted about his riches, and his confession and intercession with the Lord is very scanty; and even that which he gives is small and weak and has not power above… The rich man then supplies all things to the poor man without wavering. But the poor man being supplied by the rich makes intercession for him, thanking God for him that gave to him. And the other is still more zealous to assist the poor man, that he may be continuous in his life: for he knows that the intercession of the poor man is acceptable and rich before God. And this work great and acceptable with God, because (the rich man) has understanding concerning his riches, and works for the poor man from the bounties of the Lord, and accomplishes the ministration of the Lord rightly. Hermas (A.D. 150) Ante-Nicene Fathers vol.2 pg.32

We who valued above all things the acquisition of wealth and possessions, now bring what we have into a common stock, and communicate to every one in need. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.167

And the wealthy among us help the needy; and we always keep together; and for all things wherewith we are supplied. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.185

And if they hear that one of their number is imprisoned or afflicted on account of the name of their Messiah, all of them anxiously minister to his necessity, and if it is possible to redeem him they set him free. And if there is among them any that is poor and needy, and if they have no spare food, they fast two or three days in order to supply to the needy their lack of food. They observe the precepts of their Messiah with much care, living justly and soberly as the Lord their God commanded them. Aristides (2nd century) Ante-Nicene Fathers vol.9 pg.277

And if we owe our lives to the brethren, and have made such a mutual compact with the Savior, why should we any more hoard and shut up worldly goods, which are beggarly, foreign to us and transitory? Shall we shut up from each other what after a little shall be the property of the fire? Divinely and weightily John says, “He that loves not his brother is a murderer,” the seed of Cain, a nursling of the devil. He has not God’s compassion. He has no hope of better things. He is sterile; he is barren; he is not a branch of the ever-living supercelestial vine. He is cut off; he waits the perpetual fire. Clement of Alexandria (A.D. 195) Ante-Nicene Fathers vol.2 pg.601

The family possessions, which generally destroy brotherhood among you, create fraternal bonds among us. One in mind and soul, we do not hesitate to share our earthly goods with one another. All things are common among us but our wives.Tertullian (A.D. 198) Ante-Nicene Fathers vol.3 pg.46
