Here in The New York Times in "Are Christians Supposed to Be Communists?":
The books of the New Testament, I came to see, constitute a historical conundrum — not because they come from the remote world of late antiquity, but rather because they often appear to make no sense even in the context of antiquity. ... While there are always clergy members and theologians swift to assure us that the New Testament condemns not wealth but its abuse, not a single verse (unless subjected to absurdly forced readings) confirms the claim. ... It was all much easier, no doubt — this nonchalance toward private possessions — for those first generations of Christians. They tended to see themselves as transient tenants of a rapidly vanishing world, refugees passing lightly through a history not their own. ...
[T]he transition was not quite as abrupt as one might imagine. Well into the second century, the pagan satirist Lucian of Samosata reported that Christians viewed possessions with contempt and owned all property communally. And the Christian writers of Lucian’s day largely confirm that picture: Justin Martyr, Tertullian and the anonymous treatise known as the Didache all claim that Christians must own everything in common, renounce private property and give their wealth to the poor. Even Clement of Alexandria, the first significant theologian to argue that the wealthy could be saved if they cultivated “spiritual poverty,” still insisted that ideally all goods should be held in common.
As late as the fourth and fifth centuries, bishops and theologians as eminent as Basil the Great, Gregory of Nyssa, Ambrose of Milan, Augustine and Cyril of Alexandria felt free to denounce private wealth as a form of theft and stored riches as plunder seized from the poor. The great John Chrysostom frequently issued pronouncements on wealth and poverty that make Karl Marx and Mikhail Bakunin sound like timid conservatives. According to him, there is but one human estate, belonging to all, and those who keep any more of it for themselves than barest necessity dictates are brigands and apostates from the true Christian enterprise of charity. And he said much of this while installed as Archbishop of Constantinople.
The whole thing is a splendid summation of the ideas discussed here at this blog, and I wholeheartedly recommend that you read it.
