In its ultimate analysis, the whole subject may be reduced to a classification of the various duties which attached to the right of private property. The owner of property, as we shall see, was bound to observe certain duties in respect of its acquisition and its consumption, and certain other duties in respect of its exchange, whether it consisted of goods or of money. The whole fabric of mediæval economics was based on the foundation of private property; and the elaborate and logical system of regulations to ensure justice in economic life would have had no purpose or no use if the subject matter of that justice were abolished. It must not be understood that the mediæval writers treated economic subjects in this order, or in any order at all. As we have already said, economic matters are simply referred to in connection with ethics, and were not detached and treated as making up a distinct body of teaching. Ashley says: 'The reader will guard himself against supposing that any mediæval writer ever detached these ideas from the body of his teaching, and put them together as a modern text-book writer might do; or that they were ever presented in this particular order, and with the connecting argument definitely stated.'[1] [Footnote 1: _Op. cit._, vol. i. pt. ii. p. 387.] CHAPTER II PROPERTY SECTION 1.--THE RIGHT TO PROCURE AND DISPENSE PROPERTY The teaching of the mediæval Church on the subject of property was perfectly simple and clear. Aquinas devoted a section of the _Summa_ to it, and his opinion was accepted as final by all the later writers of the period, who usually repeat his very words. However, before coming to quote and explain Aquinas, it is necessary to deal with a difficulty that has occurred to several students of Christian economics, namely, that the teaching of the scholastics on the subject of property was in some way opposed to the teaching of the early Church and of Christ Himself. Thus Haney says: 'It is necessary to keep the ideas of Christianity and the Church separate, for few will deny that Christianity as a religion is quite distinct from the various institutions or Churches which profess it....' And he goes on to point out that, whereas Christianity recommended community of property, the Church permitted private property and inequality.[1] Strictly speaking, the reconciliation of the mediæval teaching with that of the primitive Church might be said to be outside the scope of the present essay. In our opinion, however, it is important to insist upon the fundamental harmony of the teaching of the Church in the two periods, in the first place, because it is impossible to understand the later without an understanding of the earlier doctrine from which it developed, and secondly, because of the widespread prevalence, even among Catholics, of the erroneous idea that the scholastic teaching was opposed to the ethical principle laid down by the Founder of Christianity.
