The teaching of the mediæval Church, therefore, on economic affairs was but the application to particular facts and cases of its general moral teaching. The suggestion, so often put forward by so-called Christian socialists, that Christianity was the exponent of a special social theory of its own, is unfounded. The direct opposite would be nearer the truth. Far from concerning itself with the outward forms of the political or economic structure, Christianity concentrated its attention on the conduct of the individual. If Christianity can be said to have possessed any distinctive social theory, it was intense individualism. 'Christianity brought, from the point of view of morals, an altogether new force by the distinctly individual and personal character of its precepts. Duty, vice or virtue, eternal punishment—all are marked with the most individualist imprint that can be imagined. No social or political theory appeared, because it was through the individual that society was to be regenerated…. We can say with truth that there is not any Christian political economy—in the sense in which there is a Christian morality or a Christian dogma—any more than there is a Christian physic or a Christian medicine.'[1] In seeking to learn Christian teaching of the Middle Ages on economic matters, we must therefore not look for special economic treatises in the modern sense, but seek our principles in the works dealing with general morality, in the Canon Law, and in the commentaries on the Civil Law. 'We find the first worked out economic theory for the whole Catholic world in the Corpus Juris Canonici, that product of mediæval science in which for so many centuries theology, jurisprudence, philosophy, and politics were treated….'[2]

Civilisation, vol. ii. p. 8.]
[Footnote 2: Roscher, op. cit., p. 5. It must not be concluded that all the opinions expressed by the theologians and lawyers were necessarily the official teaching of the Church. Brants says: 'It is not our intention to attribute to the Church all the opinions of this period; certainly the spirit of the Church dominated the great majority of the writers, but one must not conclude from this that all their writings are entitled to rank as doctrinal teaching' (Op. cit., p. 6).]
There is not to be found in the writers of the early Middle Ages, that is to say from the eighth to the thirteenth centuries, a trace of any attention given to what we at the present day would designate economic questions. Usury was condemned by the decrees of several councils, but the reasons of this prohibition were not given, nor was the question made the subject of any dialectical controversy; commerce was so undeveloped as to escape the attention of those who sought to guide the people in their daily life; and money was accepted as the inevitable instrument of exchange, without any discussion of its origin or the laws which regulated it.
The writings of this period therefore betray no sign of any interest in economic affairs. Jourdain says that he carefully examined the works of Alcuin, Rabanas Mauras, Scotus Erigenus, Hincmar, Gerbert, St. Anselm, and Abelard—the greatest lights of theology and philosophy in the early Middle Ages—without finding a single passage to suggest that any of these authors suspected that the pursuit of riches, which they despised, occupied a sufficiently large place in national as well as in individual life, to offer to the philosopher a subject fruitful in reflections and results. The only work which might be adduced as a partial exception to this rule is the Polycraticus of John of Salisbury; but even this treatise contained only some scattered moral reflections on luxury and on zeal for the interest of the public treasury.[1]
[Footnote 1: Jourdain, op. cit., p. 4.]
Two causes contributed to produce this almost total lack of interest in economic subjects. One was the miserable condition of society, still only partially rescued from the ravages of the barbarians, and half organised, almost without industry and commerce; the other was the absence of all economic tradition. The existence of the Categories and Hermenia of Aristotle ensured that the chain of logical study was not broken; the works of Donatus and Priscian sustained some glimmer of interest in grammatical theory; certain rude notions of physics and astronomy were kept alive by the preservation of such ancient elementary treatises as those of Marcian Capella; but economics had no share in the heritage of the past. Not only had the writings of the ancients, who dealt to some extent with the theory of wealth, been destroyed, but the very traces of their teaching had been long forgotten. A good example of the state of thought in economic matters is furnished by the treatment which money receives in the Etymologies of Isidore of Seville, which was regarded in the early Middle Ages as a reliable encyclopædia. 'Money,' according to Isidore, 'is so called because it warns, monet, lest any fraud should enter into its composition or its weight. The piece of money is the coin of gold, silver, or bronze, which is called nomisma, because it bears the imprint of the name and likeness of the prince…. The pieces of money nummi have been so called from the King of Rome, Numa, who was the first among the Latins to mark them with the imprint of his image and name.'[1] Is it any wonder that the early Middle Ages were barren of economic doctrines, when this was the best instruction to which they had access?
[Footnote 1: Etymol. xvi. 17.]
In the course of the thirteenth century a great change occurred. The advance of civilisation, the increased organisation of feudalism, the development of industry, and the extension of commerce, largely under the influence of the Crusades, all created a condition of affairs in which economic questions could no longer be overlooked or neglected. At the same time the renewed study of the writings of Aristotle served to throw a flood of new light on the nature of wealth.
The Ethics and Politics of Aristotle, although they are not principally devoted to a treatment of the theory of wealth, do in fact deal with that subject incidentally. Two points in particular are touched on, the utility of money and the injustice of usury. The passages of the philosopher dealing with these subjects are of particular interest, as they may be said, with a good deal of truth, to be the true starting point of mediæval economics.[1] The writings of Aristotle arrested the attention, and aroused the admiration of the theologians of the thirteenth century; and it would be quite impossible to exaggerate the influence which they exercised on the later development of mediæval thought. Albertus Magnus digested, interpreted, and systematised the whole of the works of the Stagyrite; and was so steeped in the lessons of his philosophic master as to be dubbed by some 'the ape of Aristotle.' Aquinas, who was a pupil of Albertus, also studied and commented on Aristotle, whose aid he was always ready to invoke in the solution of all his difficulties. With the single and strange exception of Vincent de Beauvais, Aristotle's teaching on money was accepted by all the writers of the thirteenth century, and was followed by later generations.[2] The influence of Aristotle is apparent in every article of the Summa, which was itself the starting point from which all discussion sprang for the following two centuries; and it is not too much to say that the Stagyrite had a decisive influence on the introduction of economic notions into the controversies of the Schools. 'We find in the writings of St. Thomas Aquinas,' says Ingram, 'the economic doctrines of Aristotle reproduced with a partial infusion of Christian elements.'[3]
