(M19) On the foregoing argument, which I do not now find very cogent, I would remark that we must distinguish the cases in which an effigy or an image is burnt in the fire from the cases in which it is simply carried through or over it. We have seen that in the Chinese festival of fire the image of the god is carried thrice by bearers over the glowing furnace. Here the motive for subjecting a god to the heat of the furnace must surely be the same as the motive for subjecting his worshippers to the same ordeal; and if the motive in the case of the worshippers is purificatory, it is probably the same in the case of the deity. In other words we may suppose that the image of a god is periodically carried over a furnace in order to purify him from the taint of corruption, the spells of magicians, or any other evil influences that might impair or impede his divine energies. The same theory would explain the custom of obliging the priest ceremonially to pass through the fire; the custom need not be a mitigation of an older practice of burning him in the flames, it may only be a purification designed to enable him the better to discharge his sacred duties as representative of the deity in the coming year. Similarly, when the rite is obligatory, not on the people as a whole, but only on certain persons chosen for the purpose,(56) we may suppose that these persons act as representatives of the entire community, which thus passes through the fire by deputy and consequently participates in all the benefits which are believed to accrue from the purificatory character of the rite.(57) In both cases, therefore, if my interpretation of them is correct, the passage over or through a fire is not a substitute for human sacrifice; it is nothing but a stringent form of purification. § 2.
