"Just as sex is a God-given instinct for the prolongation of the human race, so the desire for property as a prolongation of one's ego is a natural right sanctioned by natural law. A person is free on the inside because he can call his soul his own; he is free on the outside because he can call property his own. Internal freedom is based upon the fact that "I am"; external freedom is based on the fact that "I have." But just as the excesses of flesh produce lust, for lust is sex in the wrong place, so there can be a deordination of the desire for property until it becomes greed, avarice, and capitalistic aggression." Archbishop Fulton Sheen (Life of Christ)
