Clearly, when all gods have come to be more or less solar in their external and acquired features, the process of identification and internationalisation is proportionately easy.
The syncretism thus brought about in the Hebrew religion by the superposition of nature-worship on the primitive cult must have paved the way for the later recognition of { 210}monotheism, exactly as we know it did in the esoteric creed of Egypt, by making all the gods so much alike that worshippers had only to change the name of their deity, not the attributes of the essential conception. Let us look first how far this syncretism affected the later idea of Jahweh, the phallic stone-god preserved in the ark; and then let us enquire afterward how the patriotic reaction against Assyrian aggression put the final coping-stone on the rising fabric of monotheistic Jahweh-worship.
It is often asserted that Jahweh was worshipped in many places in Israel under the form of a golden calf. That is to say, Hebrews who set up images of a metal bull believed themselves nevertheless to be worshipping Jahweh. Even the prophets of the eighth century regard the cult of the bull as a form of Jahweh-worship, though not a form to which they can personally give their approbation. But the bull is probably in its origin a distinct god from the stone in the ark; and if its worship was identified with that of the Rock of Israel, it could be only by a late piece of syncretic mysticism. Perhaps the link here, as in the case of Apis, was a priestly recognition of the bull as symbolising the generative power of nature; an idea which would be peculiarly appropriate to the god whose great function it was to encourage fruitfulness. But in any case, we cannot but see in this later calf-worship a superadded element wholly distinct from the older cult of the sacred stone, just as the worship of Ra was wholly distinct in origin from the totem-cult of Mnevis, or as the worship of Amen was wholly distinct from that of Khem and Osiris. The stone-god and the bull-god merge at last into one, much as at a far later date the man Jesus merges into the Hebrew god, and receives more reverence in modern faiths than the older deity whom he practically replaces.
