It is believed that Abraham introduced fire-worship among the Jews from Ur in Mesopotamia, a land in which lights are still venerated, and fire altars are worshipped as containing the Deity.

The real essence of fire which was identical with the life-principle was holy. The "Lord" of the Israelites was in the fire which descended on Mt. Sinai, Exodus xix., 18. "The bush burned with fire and the bush was not consumed," Exodus iii., 2. Whether the signification of "bush" is the same as "grove," I know not, but Josephus assures us that the bush was holy before the flame appeared in it. Because of its sacred character, it became the receptacle for the burning "Lord" of the Jews. The ark, the religious emblem which Moses bore aloft, was simply a fire altar on which the fire must continually burn. The fact will doubtless be observed that although the ark and the bush (female emblems) were invested with a certain degree of sanctity, they were nevertheless only receptacles for the substance within them.

At the same time that the Jews kept sacred or holy fires continually burning on their altars, they carried about a serpent on a pole representing it to be the "healer of nations." They also kept a phallic emblem in a box, chest, or ark which they worshipped as the "God of Hosts," the "Life Giver," etc. It has been observed that although the Jews frequently lost their ark, they were never without their serpent-pole. At a certain stage in the religious development of mankind all the temples in Africa and Western Asia were dedicated to Vulcan the fire god or the "Lord of Fire," to whom all furnaces were sacred. The principal festivals in honor of this Deity took place in the spring, at the Easter season, and on the 23d of August, when it is said that the licentiousness practiced in the temples compared with those of the "Harvest Homes" of Europe when the sun was in Libra and the harvest had been garnered in. Vulcan was the "God of fornication" or of passion.

These excesses, which remained unchecked down to the fourth century before Christ, are said to have somewhat abated after the rise of the Stoic philosophy.

Various philosophers of early historic times as well as many of the early fathers in the Christian church believed that God was a corporeal substance which in some way is manifested through fire.

In Egypt, during the early ages of Christianity, "a great dispute took place among the monks on the question, whether God is corporeal." Tertullian declared that "God is fire"; Origen, that "he is a subtle fire"; and various others that "he is body."

There is little doubt that in early historic ages the Persians, who had undertaken to purify their religion, were the strongest and purest sect of this cult; they were in fact the genuine worshippers of the pure creative principles which they believed resided in fire.

We have observed that force or spirit was originally regarded as a part of Nature, or in other words that it was a manifestation of, or an outflowing from matter, but so soon as it began to be considered as something apart from Nature, there at once arose a desire for some corporeal object to represent this unseen and occult principle.

During many of the ages of fire-worship, holy fire, although a material substance, seems to have been too subtle to clearly represent the god-idea, hence everywhere the worship of the serpent is found to be interwoven with it. In fact, so closely are serpent, fire, pillar, and other phallic faiths intermingled that it is impossible to separate them.

The Persians are by some writers said to have been the earliest fire-worshippers: by others the truth of this statement is denied, while many claim, and indeed the Maji themselves declared, that they never worshipped fire at all in any other manner than as an emblem of the divine principle which they believed resided within it. It is probable, however, from the evidence at hand, that they, like all the other nations of the globe, prior to the reformation led by Zarathustra and his daughter, had lost or nearly forgotten the profound ideas connected with the worship of Nature.
