Ambrose of Milan : Therefore, take heed, oh wealthy person; for you also carry flesh like the poor. ... For it is written: When you have driven out the nations and have taken possession of their land, do not say: My own power and the strength of my own hand have won this possession for me (Deut. VIII, 17). Thus is the one who ascribes his wealth to himself deemed deserving. And in this manner, he does not recognize his own error, but instead drags sin along with a long rope. For if one believes that the acquisition of money is either due to chance events or dishonest cunning, then there is no place for arrogance in those who have either no praise and empty labor, or for immodest desire ignorant of setting a limit to pleasure. — The Six Days of Creation, Book 6, Chapter 8, Section 53
