Last I knew the Greek fathers are still regarded as Fathers of the Church by you Latins, and Pope Benedict XVI is given to quoting them and preaching on them to a greater extent perhaps than any Pope of Rome since the ninth century (yes, I meant ninth, not eleventh), so for the benefit of any of you who need to argue with "Catholic Worker" types, here is a quote from the Golden-Mouth of which I'm rather fond, and have posted here before:
Should we look to kings and princes to put right the inequalities between rich and poor? Should we require soldiers to come and seize the rich persons gold and distribute it among his destitute neighbors? Should we beg the emperor to impose a tax on the rich so great that it reduces them to the level of the poor and then to share the proceeds of that tax among everyone? Equality imposed by force would achieve nothing, and do much harm. Those who combined both cruel hearts and sharp minds would soon find ways of making themselves rich again.
Worse still, the rich whose gold was taken away would feel bitter and resentful; while the poor who received the gold from the hands of soldiers would feel no gratitude, because no generosity would have prompted the gift. Far from bringing moral benefit to society, it would actually do moral harm. Material justice cannot be accomplished by compulsion, a change of heart will not follow. The only way to achieve true justice is to change peoples hearts firstand then they will joyfully share their wealth.
- St. John Chrysostom on the poor from On Living Simply XLIII
You ought to get the book, On Living Simply, if you don’t have it already. I know that the passage you cited above is all over the Interwebz, but the are other reflections in the book that are not so widely republished that are equally worthwhile.
