But Ezekiel was prepared for the reception of this vision, not only by the practical reforming bent of his mind, but also by a combination in his own experience of the two elements which must always enter into a conception of this nature. If we may employ philosophical language to express a very obvious distinction, we have to recognise in the vision a material and a formal element. The matter of the vision is derived from the ancient religious and political constitution of the Hebrew state. All true and lasting reformations are conservative at heart; their object never is to make a clean sweep of the past, but so to modify what is traditional as to adapt it to the needs of a new era. Now Ezekiel was a priest, and possessed all a priest’s reverence for antiquity, as well as a priest’s professional knowledge of ceremonial and of consuetudinary law. No man could have been better fitted than he to secure the continuity of Israel’s religious life along the particular line on which it was destined to move. Accordingly we find that the new theocracy is modelled from beginning to end after the pattern of the ancient institutions which had been destroyed by the Exile. If we ask, for example, what is the meaning of some detail of the Temple building, such as the cells surrounding the main sanctuary, the obvious and sufficient answer is that these things existed in Solomon’s Temple, and there was no reason for altering them. On the other hand, whenever we find the vision departing from what had been traditionally established, we may be sure that there is a reason for it, and in most cases we can see what that reason was. In such departures we recognise the working of what we have called the formal element of the vision, the moulding influence of the ideas which the system was intended to express. What these ideas were we shall consider in subsequent chapters; here it is enough to say that they were the fundamental ideas which had been communicated to Ezekiel in the course of his prophetic work, and which have found expression in various forms in other parts of his writings. That they are not peculiar to Ezekiel, but are shared by other prophets, is true, just as it is true on the other hand that the priestly conceptions which occupy so large a place in his mind were an inheritance from the whole past history of the nation. Nor was this the first time when an alliance between the ceremonialism of the priesthood and the more ethical and spiritual teaching of prophecy had proved of the utmost advantage to the religious life of Israel.(207) The unique importance of Ezekiel’s vision lies in the fact that the great development of prophecy was now almost complete, and that the time was come for its results to be embodied in institutions which were in the main of a priestly character. And it was fitting that this new era of religion should be inaugurated through the agency of one who combined in his own
