Yahweh thundered in the heavens, and Elyon uttered his voice. (Psalms 18:13)
It's difficult to tell in most English translations, but in the Bible, there are many different ways of referring to God. The most significant are Yahweh (often translated as Lord), El (God), El Elyon (God Most High), and Elohim (Gods). It's interesting that throughout the Old Testament, whenever the phrase "son of God" is used in conjunction with Yahweh it always refers to humans, while whenever "son of God" is used with El/El Elyon/Elohim it refers to angels. This indicates that Elyon and Yahweh are actually two distinct personages, the Father and the Son.
In the earliest Jewish writings, Elyon was the Most High and Yahweh was one of his sons who was responsible for Israel. Elyon had other sons who were the gods of the other nations in the world (see Septuagint and Dead Sea Scrolls versions of Deuteronomy 32:8-9). References to Yahweh's fellow gods were removed during the Deuteronomic reform after the Babylonian Exile, however traces of them remain (Genesis 6:2-4, Deuteronomy 32:43, Hebrews 1:6, Isaiah 14:32, Daniel 10:13-14, Job 38:7, Jubilees 2:1,4, Psalms 29:1, Psalms 89:6, Psalms 58, etc.). They are sometimes called messengers, angels, princes, or other names.
English translations often obscure the passages about them. For example, Job 1:6 literally says "Now there was a day when the sons of El Elyon set themselves against Yahweh and Satan came also among them" but the King James Version translates this as "Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them."
The Israelite god Yahwen and the Canaanite storm god Ba'al Haddu have a lot in common. For example, the theophanies of Yahweh resemble the appearances of Ba'al in the Ugaritic texts (Job 38, Ezekiel 1:4, Isaiah 24:19-23, 34:8-10, 42:13-15, 59:16-19).
The Babylonian king is associated with a god called the Day Star, one of the sons of El in the Ugaritic texts. Day Star is also called Lucifer (Isaiah 14:12), not to be confused with Satan who is a different god altogether. Just like the planet Venus (a.k.a. the morning star) is the brightest object in the sky before sunrise, so too Day Star appears to be the mightiest god. However, when the sun does rise, Babylon's god, like Venus, will disappear in the face of the sun (Yahweh). Yahweh vows to destroy another god in Ezekiel 28:12-19, this one associated with the King of Tyre.
Yahweh had the form of a man and carried a sword filled with blood (Isaiah 34:6). He protected Israel and did battle with their enemies. He appointed their high priest and was their redeemer and judge. Ezekiel described Yahweh as being bronze from the waist up and made of fire from the waist down with a rainbow surrounding him (Ezekiel 1:27-28). Daniel describes a similar figure made of bronze and fire (Daniel 10:5-6).
Leviticus 16 describes a ritual in which the sins of the people are placed upon a goat which is driven out into the desert "for" Azazel, although the Hebrew can also be translated "as" Azazel, meaning the goat is being punished for Azazel's rebellion in 1 Enoch 10:5 and The Book of Giants from the Dead Sea Scrolls. A second goat, perhaps representing Yahweh, is slain for purposes of atonement. Thus, the god symbolically dies for the sins of the people which becomes a major idea in Christianity later on.
I am Yahweh. I appeared to Abraham, to Isaac and to Jacob as El Shaddai, but by my name Yahweh I did not make myself known to them. (Exodus 6:2-3)
After the Deuteronomic reform, Yahweh and Elyon were combined together into one god. When Moses talks to the burning bush (Exodus 3:2-7), the Angel of Yahweh, Elohim, and Yahweh all speak to him at different times, indicating these terms were used as synonyms, although early Christians may have read the trinity into this story.
In the early centuries of Christianity, a main focus of rabbinic Judaism was to discredit the idea that there were two gods. According to the Mekhilta of R. Ishmael, this idea apparently came about due to two different appearances of Yahweh in Exodus. In Exodus 15:3, Yahweh is a man of war, indicating that he is a young warrior. In Exodus 24:10, Yahweh is giving Law, the activity of an old man. R. Ishmael tries to explain this apparent contradiction away by explaining that Yahweh can appear in different forms and he cites Daniel 7 as an example. It's a strange example to cite, however, since Daniel 7 portrays two distinct gods. Yahweh (Son of Man) is depicted as the young warrior god succeeding the elderly El Elyon (Ancient of Days).
In the Deuteronomic writings, the goddess Asherah is always linked with Ba'al, however in extra-Biblical Hebrew writings, Asherah is linked with Yahweh, and in Canaanite texts of the first millennium, she is never linked with Ba'al. It seems the Deuteromists connected Asherah with Ba'al in an effort to discredit both, but Asherah was originally Yahweh's consort, not Ba'al's.
We know Asherah was worshiped in Israel, since we are repeatedly told that she was purged from the Temple (2 Kings 23:6-7, 18:4, 21:7, 13:6, 23:6, 1 Kings 15:13, 18:19, 18:40). These purgings didn't seem to take effect, since she always seemed to come back. She is described by Ezekiel in terms similar to Lady Atirat, consort of El and mother to seventy sons in the Ugaritic literature.
We also know she was Yahweh's consort from archealogical evidence. There are inscriptions mentioning "Yahweh and his Asherah" at Kuntillet 'Ajrud and Khirbet-el-Qom. There is a cultic stand at Taanach which has two Asherah scenes and two Yahweh scenes. Asherah is sometimes depicted as a tree (see Deuteronomy 16:21, 7:5, 12:3, 1 Kings 14:23, 14:15, 16:33, 2 Kings 17:10, 17:16, Proverbs 3:18, Sirach 24:13-22) while Yahweh was depicted as a sun horse. Female figurines have been found at many Israelite sites, including at the royal palace of Ramath Rachel, indicating that worship of a female deity was not limited to the common people. Horse figurines, some with sun disks around their heads, have also been found in Jerusalem, not far from the temple (see 2 Kings 23:11, Revelation 19:11-16).
Digging into the texts, Margaret Barker finds evidence that Yahweh's female aspect or consort, Wisdom, was suppressed by the Deuteronomists (1 Enoch 94:5, Deuteronomy 4:6, Baruch 3:12, Baruch 3:36-37, Pistis Sophia). Kabbalistic writings speak of the exile of the female aspect of Yahweh called Shekinah. Jeremiah calls this figure the Queen of Heaven (Jeremiah 44:17-18). A female god is also mentioned in Micah 5:3 and Isaiah 7:14. Yahweh is sometimes described in feminine terms, such as giving birth to Israel (Deuteronomy 32:11,18, Isaiah 42:14, see also Isaiah 45:9-11, Isaiah 49:14-15, Isaiah 66:13).
Not only was Yahweh's female aspect called the Spirit of God or Wisdom in the Old Testament, but many early Christians considered the Holy Spirit of the trinity to be female. The greatest church in Byzantium was named Hagia Sophia after Wisdom. Words Matthew 23:34 attributes to Jesus are attributed to Wisdom in Luke 11:49 and Paul describes Jesus as the Wisdom of God in 1 Corinthians 1:24.
Origen speaks of a similar Jewish tradition in which God has a masculine aspect called the Word and a feminine aspect called the Spirit. The canonical Gospels don't tell us who declared Jesus the beloved son during the baptism, we simply assume it was the Father. However, the Gospel of the Hebrews (now lost, but quoted by Origen and Jerome) states that the Holy Spirit is the Mother of Jesus and it was she who declared Jesus her son during the baptism.
Instead of making the usual assumption that gnosticism is a heretical form of Christianity, Margaret Barker takes a close look at the texts and finds that gnosticism has more in common with pre-Deuteronomic Judaism. Gnosticism is exactly what you'd expect to find if a group of Jews rejected the monotheistic reform and held onto the earlier beliefs. They grew to view Judaism as the enemy and the god of the Jews as evil, although they still believed in a good god. One gnostic text points out that Yahweh admits he isn't the only god when he says that he is a jealous god. If there was no other god, why would he be jealous? (Apocryphon of John II:1:11-13)
The Gnostics also speak of a female aspect of god called Sophia who shared a lot in common with the Wisdom of the Bible. She was said to be the tree of knowledge in the garden of Eden (Apocryphon of John II:1:22, Hypostatis of the Archons II:4:94, 1 Enoch 32:3-6, Proverbs 3:18).
There are a few scattered references that link men with angels. The Prayer of Joseph, an early Jewish work which has not survived the ravages of time, but is quoted in part by Origen, says that the archangel Israel was chief captain of the heavenly hosts before coming to earth as Jacob. According to the gnostic text On the Origin of the World, Jesus became the angel Israel (literally 'the man who sees God').
In apocalyptic writings, humans are referred to as animals and angels are referred to as men. Thus, when Noah is born a bull and becomes a man (1 Enoch 89:1) and Moses is a sheep who becomes a man (1 Enoch 89:36), what's really being described is the process of them becoming angels. The New Testament describes Jesus going through a similar transformation (Philippians 2:9-11).
The archangel Metatron used to be the man known as Enoch (3 Enoch 4:3). Metatron is known as the Little Yahweh, which implies there were two Yahwehs. Many early Christian and gnostic texts refer to two different Lords or Yahwehs (Pistis Sophia, Book of Jeu, Gannat Bussame, Sirach 51:10, Ascension of Isaiah 9:40, 10:7, Eusebius, 1 Corinthians 8:5-6)
The early Jewish writer Philo believed in two separate gods, one called Logos (the Word). He describes the Logos in terms used for Yahweh, meaning that for Philo, Yahweh was the Word. To the early Christians, Jesus was Yahweh. He is called son of the Most High (Luke 1:32, Mark 5:7), but never son of the Lord. However, he is called Lord himself all throughout the New Testament. Early Christian writers such as Clement of Alexandria and Theodotus equated Jesus with Philo's Logos (see also John 1, 1 John 1:1-2, Revelation 19:11-16, Hebrews 4:12, 2 Peter 3:5-7).
Early Christians such as Justin, Irenaeus of Lyons, Clement of Alexandria, Hippolytus of Rome, and Novatian believed there were two separate gods. Unlike modern translators, Eusebius read the Hebrew of Psalm 91:9 correctly: "You, O Yahweh, are my refuge, you have made Elyon your dwelling place." (Proof IX:7) Two distinct gods are clearly referenced, yet modern readings are based on what the translators think it should have said. Eusebius goes on to demonstrate that the Hebrew of Psalms 45:7 indicates the the Anointed One is a second god, not a priest: "Thou hast, O God, loved justice and hated impiety: therefore in return, O God, the highest and greater God, Who is also thy God hath anointed thee." (Proof IV:15)
The early Christians prayed to Jesus as if he were Yahweh (1 Corinthians 16:22, Didache 10:6). Several early versions of John 1:18 read "the only begotten GOD who is in the bosom of the Father" instead of "only begotten Son" (Codex Sinaiticus, Codex Vaticanus, parts of Irenaeus and Origen). Barker goes on to quote numerous New Testament passages which name Jesus as God. Jesus is called the Savior in the New Testament, while the Old Testament constantly refers to Yahweh as the Savior.
2 Corinthians and the Epistle to the Hebrews both imply that Jesus was present at the Exodus. Two of the most important early manuscripts of Jude, verse 5 (Codex Vaticanus and Codex Alexandrinus) actually read, "Jesus saved a people from the land of Egypt." This isn't surprising after reading the numerous passages in the New Testament which clearly identify Jesus as Yahweh.
