The letter is here given in full because often more force is carried by the reference to a great name than by the study of his argument. A careful reading of this letter does not reveal a positive approval of usury. He merely excuses it by suggesting other evils that he thinks worse; for instance, that land rentals may be worse than the usury of money. He does not mention the necessary oppression of the poor tenants by the loan upon a mortgage.
It is proof of the weakness of the case when this letter is the most favorable that can be presented from any ecclesiastic.
