The Doctor on the Economy

Doctor of the Church, that is.  St. Basil the Great says:

They say: whom do I wrong by keeping my property? What, tell me, is your property? Where did you find it and brought it to your life? Just like someone in the theatre, who had a seat and then stopped those who entered, judging that what lies common in front of everyone to use, was his own: rich men are of the same kind. They first took possession of the common property, and then they keep it as their own because they were the first to take it. If one had taken what is necessary to cover one's needs and had left the rest to those who are in need, no one would be rich, no one would be poor, no one would be in need.

Isn't it true, that you fell off the womb naked? Isn't it true, that naked you shall return to the earth? Where is your present property from? If you think that it came to you by itself, you don't believe in God, you don't acknowledge the creator and you are not thankful to Him who gave it to you. But if you agree and confess that you have it from God, tell us the reason why He gave it to you.

Is God unjust, dividing unequally the goods of our life? Why are you rich, while the other is poor? Isn't it, if not for any other reason, in order for you to gain a reward for your kindness and faithful providence, and for him to be honored with the great awards of patience? But you, having gathered everything inside the bosom of avarice which is always empty, do you think that you wrong no one, while you strip so many people?

Who is the greedy person? It's him, who doesn't content himself with what he has. And who strips? He who steals what belongs to the others. And you think that you are not greedy, and that you do not strip the others? What was granted to you, in order for you to take care of the others, you took it and you made it your own. What do you think?

He who strips the clothed is to be called a thief. How should we name him, who is able to dress the naked and doesn't do it, does he deserve some other name? The bread that you possess belongs to the hungry. The clothes that you store in boxes, belong to the naked. The shoes rotting by you, belong to the bare-foot. The money that you hide belongs to anyone in need. You wrong as many people as you could help.

From Homily On Avarice 7

This is not a denial of the right to property, or that the wealthy can be good--it just indicates that the rich man can all to easily become he who cried out to Father Abraham for a single drop of water.
