Monotheism was a late adaptation of Jewish belief. The Israelites originally believed in multiple gods, including a son of God and a wife of God. It astonishes me that Christians don't know who they are, and from whence their traditions came.
It is no surprise that we find archeology evidence of people worshipping other Gods alongside YHVH when the Bible explicitly tells us that Israel was involved in this sin and was carried away into captivity because of it.
However, your assertion that this was seen as a normal expression of Biblical faith in God, rather than an abberation of legitimate Biblical worship of God, is proveably wrong - Both scripturally and historically.
Scripturally because the idolatrous worship of other Gods, and worship of God in pagan ways, was expressly condemned by God and resulted in judgement upon the Israelites.
In fact, we see in Jeremiah 44:15-23 what is quite probably a direct reference to Israel's idolatrous and blasohemous pairing of God with an idol as wife when it refers to them worshipping the so-called "queen of heaven".
Furthermore, we know from archeology that the name they gave the consort of YHVH was "Asherah"; and guess what is says about Asherah in the Bible:
It is expressly forbidden to practice the worship of Asherah - Deuteronomy 16:21
It is linked with idolatrous practices that led Israel astray from the one true God and provoked His anger - Judges 6:25, Judges 6:28, 1 Kings 15:13, 1 Kings 16:33, 2 Kings 13:6, 2 Kings 17:16, 2 Kings 21:3, 2 Kings 21:7, 2 Kings 23:4-7, 2 Kings 23:15, 2 Chronicles 15:16, Micah 5:14.
It was the prophets of Asherah that were the idolatrous false prophets opposing Elijah, the ones who led the nation of Israel into disasterous abandonment of YHVH under Ahab - 1 Kings 18:19
Historically, we can see when the Jews came back from Babylonian captivity, and even moreso after asserting their independence over greek influence, idolatry was no longer a major issue for the Jewish people. They worshipped the one true God - and no longer tried to corrupt the worship of YHVH by attaching pagan symbolism, rituals, and deities onto what God had revealed and commanded to them. Their biggest problem by the time Jesus came on the scene was rebellion in the sense of demanding adherence to man made authority over the authority of God's true commands (legalism), and the pride associated with it.
Historically we don't see evidence of this dual alliegence to idols and YHVH at the same time during the 2nd temple period, especially around the time of Jesus.
So it's very odd that you would try to claim that polytheism was the natural state of Judaism when everything in scripture was against it and idolatrous worship of other Gods was given as the cause of their exile from the land. Furthermore it ceased to be the practiced by the Jewsish people long before Jesus appeared on the scene, and it's practice has never been taken up again by Jews - because that is what happens when you actually try to follow what the Bible says.
By establishing himself as the Son of God, Jesus condemned monotheism.
As I established already in this post using the scripture, it can be shown there there is only one God. Jesus would not condemn that which God has declared to be true through His prophets in the Bible.
Your synopsis of LDS belief is from a hostile source, and should not be relied upon.
If there is anything I have stated about what LDS scripture or doctrine says about the nature of God and Jesus then I welcome you to point out what specifically I got wrong, and why.
I don't see anything in your post that points out how any of the statements I made was not in line with what the LDS believe.
I have to ask you first what do you mean by virgin, in light of what Mormon leaders have said:
"The birth of the Saviour was as natural as are the births of our children; it was the result of natural action. He partook of flesh and blood--was begotten of his Father, as we were of our fathers," -Brigham Young, Journal of Discourses, v. 8, p. 115
"Christ was begotten by an Immortal Father in the same way that mortal men are begotten by mortal fathers," -Bruce McConkie (member of first council of seventy), Mormon Doctrine, 1966, p. 547
""For our present purposes, suffice it to say that our Lord was born of a virgin, which is fitting and proper, and also natural, since the Father of the Child was an immortal Being" -Bruce McConkie, The Promised MEssiah, pg 466.
"And Christ was born into the world as the literal Son of this Holy Being; he was born in the same personal, real, and literal sense that any mortal son is born to a mortal father. There is nothing figurative about his paternity; he was begotten, conceived and born in the normal and natural course of events, . . . Christ is the Son of Man, meaning that his Father (the Eternal God!) is a Holy Man," -Mormon Doctrine, by Bruce McConkie, p. 742).
"The fleshly body of Jesus required a Mother as well as a Father. Therefore, the Father and Mother of Jesus, according to the flesh, must have been associated in the capacity of husband and wife; hence the Virgin Mary must have been, for the time being, the lawful wife of God the Father: we use the term lawful wife, because it would be blasphemous in the highest degree to say that He overshadowed her or begat the Savior unlawfully........He had a lawful right to overshadow the Virgin Mary IN THE CAPACITY OF A HUSBAND, and beget a Son.......Whether God the Father gave Mary to Joseph for time only, or for time and eternity, we are not informed. It may be that He only gave her to be the wife of Joseph while in this mortal state, and that He intended after the resurrection to again take her as one of his own wives to raise up immortal spirits in eternity." -"Apostle" Orson Pratty
So essentially they are claiming that Mary had a sexual relationship with God the Father in order to produce Jesus the Son, yet she is still considered a virgin because God is immortal.
That would be nonsense because the word "virgin" loses all sense of it's meaning if you try to claim that someone can have sex and still be a virgin.
The implication in the Bible when it says Mary "has known no man" in Luke 1:34 is that she has no had any intercourse with a man.
I'd must point out that this was actually the only issue you even tried to deny as untrue out of my long list of what Mormons believe. If you are trying to tell me that you don't take issue with the other things I stated, then you've got much bigger theological contradictions to be dealing with between the LDS writings and the Bible than just the issue of Mary's virginity. Mary at that point becomes the least conccerning of the things on that list when everything Mormon writings teach about the nature of God, Jesus, and the purpose and plan of God, stands in direct opposition to Biblical truth. There are no greater core fundamental truths in the Bible than those issues - You cannot contradict those with nonbiblical writings and still claim to be following a Bible based faith in the one true God.
The Bible supports the idea that God did not create the universe. Read the 1st chapter of John. It explicitly states that Jesus only created the things that were created. That would be a pointless and misleading observation if he created everything.
You can see in the extensive list of verses I gave that the scripture lists both God and Jesus as the source of creation, using all terms that refer to God in multiple languages (Elohim, YHVH, Jesus, Kyrios, and Theos).
It also infers that he wasn't alone.
This is where the trinitarian aspect of Jesus per-existing before creation with the Father comes in. It can be suggested when he said "let us make man in our image" that it was the Father conversing with the Son.
Additionally, God asks Job where he was when the earth was created and "all the sons of god shouted for joy".
There is theological debate about what exactly the Beni'Elohim (Sons of God, often translated as Angels) refers to exactly; and therefore debate over what is meant exactly when God said "let us make man in our image" (was the Father talking to the Son, or the Son talking to the Beni'Elohim which could be angels?)...
However, such questions ultimately don't matter when it comes to establishing whether or not Mormonism is consistent with the Bible - because regardless of what debate may exist over the Beni'Elohim; there are three things which we can be absolutely certain about based on the scriptures (many of which I listed already):
1. That Jesus existed before creation with God.
2. That Jesus is God.
3. That through Jesus, God, creation came into being.
Yet, LDS writings and doctrines contradict those Biblical truths. So at that point it doesn't really matter what Beni'Elohim means in the context of Genesis 1 with regards to whether or not Mormonism is true, because we already know that LDS views cannot be reconciled with what the Bible says is true.
