The idea of the biblical God changes throughout the course of the Bible as does the name, and there seem to be several changes of Deity. For example:
- The God in the Genesis creation story is called Elohim. The Elohim are the sons of El in the Canaanite pantheon. They were ruled by El Elyon (God Most High), and later by Hadad the rain god, who is generally the god referred to by the title Baal (Lord). In Genesis 14:18-22, Abram is blessed by Melchizedek, the Canaanite High Priest of El Elyon and king of Salem, and Abram accepts the god as his. The enemy of the Elohim is Yam (the sea), a chaos monster slain by Baal. This might have been derived from the Sumerian creation epic Enuma Elish, in which the god Marduk battles the great dragon Tiamat (the waters of chaos, and mother of the gods) and divides her body to create the heaven and the earth. In Genesis 1, God's Spirit moves upon the face of the waters (verse 2) and then divides them (verses 6-7). Marduk hangs up his bow after his victory over Tiamat, much as God does in Genesis 9:13 after the Flood.
- In Genesis 14, Abraham is blessed by Melchizedek. the king of Salem that Abraham and other kings have just conquered. Melchizedek was also the High Priest of the "Most High God" of the Canaanite pantheon (El Elyon). Abraham assimilates the attributes of this god into his own.
- When Moses encounters God, God introduces himself as Yahweh (I am who am, I will be what I will be, etc). Continuity with previous beliefs is maintained by the claim to be the God of Abraham, Isaac and Jacob.
-Exodus 19:9 makes him appear to be a thunder god - And the LORD said unto Moses, Lo, I come unto thee in a thick cloud, that the people may hear when I speak with thee, and believe thee for ever. And Moses told the words of the people unto the LORD.
-In Exodus he also looks like fire, for example Chapter 19 Verse 18.
-Exodus 34:5, still a storm god - And the LORD descended in the cloud, and stood with him there, and proclaimed the name of the LORD.
-1 Kings 19:11-12 suggests that God isn't in wind, earthquake or fire, but in a still, small voice - And he said, Go forth, and stand upon the mount before the LORD. And, behold, the LORD passed by, and a great and strong wind rent the mountains, and brake in pieces the rocks before the LORD; but the LORD was not in the wind: and after the wind an earthquake; but the LORD was not in the earthquake: And after the earthquake a fire; but the LORD was not in the fire: and after the fire a still small voice.
- In Acts 17, Paul further assimilates the attributes of Greek gods into the deity, when he identifies the "unknown god" as the one he is teaching about.
