Nevertheless, the Church has given no positive approval to any of the foregoing theories. In the last formal pronouncement by a Pope on the subject, Benedict XIV[136] condemned anew all interest that had no other support than the intrinsic conditions of the loan itself. At the same time, he declared that he had no intention of denying the lawfulness of interest which was received in virtue of the title of "lucrum cessans," nor the lawfulness of interest or profits arising out of investments in productive property. In other words, the authorisation that he gave to both kinds of interest was merely negative. He refrained from condemning them. In the Responses given by the Roman Congregations from 1822 onward to questions relating to the lawfulness of loan-interest, we may profitably consider four principal features. First, they declare more or less specifically that interest may be taken in the absence of the title of "lucrum cessans"; second, some of them definitely admit the title of "praemium legale," or civil authorisation, as sufficient to give the practice moral sanction; third, they express a genuine permission, not a mere toleration, of interest taking; fourth, none of them explicitly declares that any of the titles or reasons for receiving loan-interest will necessarily or always give the lender a _strict right_ thereto. None of them contains a positive and reasoned approval of the practice. Most of them merely decide that persons who engage in it are not to be disturbed in conscience, so long as they stand ready to submit to a formal decision on the subject by the Holy See. The insertion of the latter condition clearly intimates that some day interest taking might be formally and officially condemned. Should such a condemnation ever appear, it would not contradict any moral principle contained in the "Roman Responses," nor in the present attitude of the Church and of Catholic moralists. Undoubtedly it could come only as the result of a change in the organisation of industry, just as the existing ecclesiastical attitude has followed the changed economic conditions since the Middle Ages.
