In matters of belief the Eastern church nearly approaches the Anglican, the main divergence is that whereas the Anglican and Roman churches agree that the Holy Ghost proceeds from the Father and the Son, the Eastern Church holds that it proceeds from the Father only. The bible may be read; the church may interpret its teaching, "for the traditions of the church have been maintained uncorrupted through the influence of the Holy Spirit." God the Father, the Son, and the Holy Ghost, "perfectly equal in nature and dignity," may alone be worshipped; but homage may be paid to the Virgin Mary, and reverence shown to the saints, to ikons and to relics. That this may not be abused, bishops at their consecration are requested to promise that "honour shall be shown to God only, not to the sacred ikons, and that no false miracle shall be ascribed to them.... The _moshi_ or incorruptible remains which are so greatly venerated, are the corpses of those long dead, whose burial-place has been forgotten and is made known by a supernatural manifestation. These remains must not be subject to the ordinary process of decay, and may possess such virtue as to miraculously cure the sick--which is the quality usually attributed to them." The ecclesiastical architecture of Moscow, or of Russia, is not so complex as it appears to be at first sight; originally the place for Christian worship was but a square log-hut; add an apse at the east end, cover the building with a dome roof supporting a cross to indicate its sacred character, and the external structure of the primitive church is complete. Instead of a dome roof it was found easier, as larger buildings became necessary, to cover with the dome only the centre of the church, which was still further elevated to make more prominent the dome and cross denoting the purpose of the building. Three apses, symbolic of the Trinity, took the place of one; five and seven are sometimes found. When the idea of the original whole dome roof was expressed by four small domes arranged around the higher central one, the model became the permanent type from which all other forms have been elaborated. The primitive type is best exemplified in the church of St Michael within the Chudov monastery, but the cathedrals of the Assumption and of the Archangels, on the Sobornia Ploshchad of the Kremlin, will serve equally well to illustrate the permanent form. The origin and development of the bulbous dome, as well as the size, position and number of secondary domes, may be traced by comparing the various old churches in South Russia, and those of wood, formerly or at present existing in "wooden" Russia. For this purpose a convenient series of framed drawings is to be found on stands in Room [Greek: B] of the Historical Museum. They confirm what has already been stated in the preceding chapter, concerning the origin of Russian architecture, and
