It is not surprising that the results of the investigations of two schools, having aims so diverse in view, should be mutually incompatible. According to the views of some members of the ritualistic school, the vestments of the Christian Church were modelled directly upon the vestments of the Jewish priesthood; and as minute instructions for the shapes and usage of the latter were laid down in the divinely-revealed laws of Moses, they thus claim an at least indirect Divine appointment for the Christian vestments. The antiquarian party, on the other hand, are unanimous in holding that the vestments of the Christian Church were evolved, by a natural process, from the ordinary costume of a Roman citizen of the first or second century of our era. The consideration of these two theories must first occupy our attention. Neither is absolutely correct; for, although the balance of probability is enormously in favour of the second view, yet this theory, in the form in which it is often stated, does not cover certain changes which were made in the textures, outlines, and number of the vestments while the Church was yet comparatively young. These changes were all introduced to assimilate, as far as possible, the Jewish and Christian systems; and thus it may be said that both views contain an element of truth. The theory of a Levitical origin is the older of the two; in fact, it was the first, and for many years the only, solution proposed. We shall therefore at the outset devote a page or two to considering its merits. Very few, even among the students of the ritualistic school, now hold it absolutely. The weight of argument which can be brought to bear against it is so great that it is almost universally abandoned as untenable. For comparative purposes, it will be necessary at this stage to introduce a short descriptive catalogue of the vestments of the Levitical priesthood, as prescribed in the Book of Exodus (chap. xxviii). Josephus ('Antiquities,' iii 7) is also a _locus classicus_ on the subject, and some additional particulars from that source are here incorporated: I. _The Drawers or 'Breeches' of Linen._ II. _The Tunic of Linen_ ('coat of fine linen,' Exod. xxviii 39).—Josephus tells us that this tunic was of fine linen or flax doubled; that it reached to the feet, fitting close to the body, and was furnished with tight sleeves. It was girded to the breast, a little above the level of the elbows, by III. _The Girdle._—This was a strip of linen which, according to Josephus, was four fingers broad; according to Maimonides,[1] three fingers broad and thirty-two cubits long. It was wound many times round the body; the ends were then tied over the breast and hung down to the feet, except when the priest was engaged in sacrifice or other service, in which case he threw it over his left shoulder, so that it should not impede him in his duty. It was elaborately embroidered with flowers, worked in scarlet, purple, and blue threads.
