ABSTRACT
By the seventeenth century the clearest thinkers in the Roman Church saw that her theology must be readjusted to political economy: so began a series of amazing attempts to reconcile a view permitting usury with the long series of decrees of popes and councils forbidding it. Social science as applied to political economy had gained a victory final and complete. The dealings of theology with public economy were by no means confined to the taking of interest for money. In 1872 the Holy Office, answering a question solemnly put by the Bishop of Ariano, as solemnly declared that those who take eight per cent interest per annum are "not to be disquieted"; and in 1873 appeared a book published under authority from the Holy See, allowing the faithful to take moderate interest under condition that any future decisions of the Pope should be implicitly obeyed. Social science as applied to political economy had gained a victory final and complete.
