The Bible says: (Just a couple of scriptures about One God.)
Deuteronomy 4:35 and 4:39 and 6:4
To you it was shown, that you might know that the LORD Himself is God; there is none other besides Him.
Therefore know this day, and consider it in your heart, that the LORD Himself is God in heaven above and on the earth beneath; there is no other.
"Hear, O Israel: The LORD our God, the LORD is one!"
2 Samuel 7:22
Therefore You are great, O Lord GOD. For there is none like You, nor is there any God besides You, according to all that we have heard with our ears.
1 Kings 8:60
That all the peoples of the earth may know that the LORD is God; there is no other.
Before the mountains were brought forth, Or ever You had formed the earth and the world, Even from everlasting to everlasting, You are God.
Isaiah 42:8 and 43:10-11 and 44:6-8 and 45:5 and 45:14 and 45:18 and
45:21-22 and 46:9 and 47:8 and 47:10
I am the LORD, that is My name; And My glory I will not give to another, Nor My praise to carved images.
"You are My witnesses," says the LORD, "And My servant whom I have chosen, That you may know and believe Me, And understand that I am He. Before Me there was no God formed, Nor shall there be after Me. I, even I, am the LORD, And besides Me there is no savior.
"Thus says the LORD, the King of Israel, And his Redeemer, the LORD of hosts: 'I am the First and I am the Last; Besides Me there is no God. And who can proclaim as I do? Then let him declare it and set it in order for Me, Since I appointed the ancient people. And the things that are coming and shall come, Let them show these to them. Do not fear, nor be afraid; Have I not told you from that time, and declared it? You are My witnesses. Is there a God besides Me? Indeed there is no other Rock; I know not one."
I am the LORD, and there is no other; There is no God besides Me. I will gird you, though you have not known Me,
..... saying, 'Surely God is in you, And there is no other; There is no other God.'"
For thus says the LORD, Who created the heavens, Who is God, Who formed the earth and made it, Who has established it, Who did not create it in vain, Who formed it to be inhabited: "I am the LORD, and there is no other."
..... Who has declared this from ancient time? Who has told it from that time? Have not I, the LORD? And there is no other God besides Me, A just God and a Savior; There is none besides Me. "Look to Me, and be saved, All you ends of the earth! For I am God, and there is no other.
Remember the former things of old, For I am God, and there is no other; I am God, and there is none like Me,
"Therefore hear this now, you who are given to pleasures, Who dwell securely, Who say in your heart, 'I am, and there is no one else besides me; .....
"For you have trusted in your wickedness; You have said, 'No one sees me'; Your wisdom and your knowledge have warped you; And you have said in your heart, 'I am, and there is no one else besides me.'
Mark 12:29-30 and 12:32
Jesus answered him, "The first of all the commandments is: 'Hear, O Israel, the LORD our God, the LORD is one. And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength.' This is the first commandment.
So the scribe said to Him, "Well said, Teacher. You have spoken the truth, for there is one God, and there is no other but He.
I and My Father are one.
1 Corinthians 8:4-6
Therefore concerning the eating of things offered to idols, we know that an idol is nothing in the world, and that there is no other God but one. For even if there are so-called gods, whether in heaven or on earth (as there are many gods and many lords), yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live.
There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all.
You believe that there is one God. You do well. Even the demons believe--and tremble!
1 John 5:7
For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one.
"I am the Alpha and the Omega, the Beginning and the End," says the Lord, "who is and who was and who is to come, the Almighty."
The following is from www.carm.org describing Christianity. (Christian Apologetics & Research Ministry)
True Christian doctrine is that there is only One God who has ever existed anywhere, anyplace, anytime. God is the only Supreme Being in existence in the entire universe. He is the creator of all things. He alone is God. There have never been any Gods before Him nor will there be any after Him. God is God from all eternity. Just One. God doesn't even know of any other Gods. This is called Monotheism.
So to sum it up... There is, always has been, and always will be Only One God. Biblical Christianity teaches Monotheism.
The LDS doctrine of God:
God and Jesus are two completely separate Beings. Jesus is the literal Son of God, meaning They are Two Gods. Other Gods have been formed both before and after Him. LDS God has a father, mother, grandparents, brothers, sisters, etc. Also there are other Gods for other worlds.
This practice is called Polytheism, and Polytheism is not a Biblical Christian practice.
The following is from www.carm.org describing Mormonism.
The god of earth is only one of many, many gods (Bruce McConkie, Mormon Doctrine, p. 163). This is called polytheism. However, they worship only one of the many gods, the one called Elohim. This is called monolatry.*
*Monolatry is the belief that there is more than one God, but only one is served and worshiped. Mormonism is an excellent example of monolatry. Mormonism teaches the existence of many Gods of many worlds, yet worships only the one of this planet. Therefore, monolatry is a division of polytheism, the belief in many gods. This is a false teaching contrary to Scripture.
Elohim (as the Mormons like to call the Father) used to be a man on another planet (Mormon Doctrine, p. 321). Elohim became a God and came to this world with his goddess wife (Articles of Faith, by James Talmage, p. 443). Mormons have the potential of becoming gods of their own worlds (Teachings of the Prophet Joseph Smith, pages 345-347, 354).
According to that which was ordained in the midst of the Council of the Eternal God of all other gods before this world was, that should be reserved unto the finishing and the end thereof, when every man shall enter into his eternal presence and into his immortal rest.
The Father has a body of flesh and bones as tangible as man's; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit. Were it not so, the Holy Ghost could not dwell in us.
D&C 132:18-20 and 132:37
.....when they are out of the world it cannot be received there, because the angels and the gods are appointed there, by whom they cannot pass; ..... and shall be of full force when they are out of the world; and they shall pass by the angels, and the gods, which are set there, to their exaltation and glory in all things, as hath been sealed upon their heads, which glory shall be a fulness [sic.] and a continuation of the seeds forever and ever. Then shall they be gods, because they have no end; therefore shall they be from everlasting to everlasting, because they continue; then shall they be above all, because all things are subject unto them. Then shall they be gods, because they have all power, and the angels are subject unto them.
Abraham received concubines, and they bore him children; and it was accounted unto him for righteousness, because they were given unto him, and he abode in my law; as Isaac also and Jacob did none other things than that which they were commanded; and because they did none other things than that which they were commanded, they have entered into their exaltation, according to the promises, and sit upon thrones, and are not angels but are gods.

GODHEAD, Plurality of Gods, Joseph Smith
I will preach the plurality of Gods. ..... I wish to declare I have always and in all congregations when I have preached on the subject of the Deity, it has been the plurality of Gods. ..... separate and distinct personage .....these three constitute three distinct personages and three Gods. ..... three Gods ..... they are plural ..... Gods many and Lords many ..... and is he authorized to say that there is only one God? He makes himself a fool if he thinks or says so ..... head God ..... heads of the Gods ..... The head one of the Gods ..... Many men say there is one God ..... I say that is a strange God anyhow--three in one, and one in three! It is a curious organization. .....
..... If Jesus Christ was the Son of God, and John discovered that God the Father of Jesus Christ had a Father, you may suppose that He had a Father also. Where was there ever a son without a father? And where was there ever a father without first being a son? Whenever did a tree or anything spring into existence without a progenitor? And everything comes in this way. Paul says that which is earthly is in the likeness of that which is heavenly, Hence if Jesus had a Father, can we not believe that He had a Father also? I despise the idea of being scared to death at such a doctrine, for the Bible is full of it. .....
It is very clear that not only did the founding prophet of the LDS church believe and preach Polytheism and Monolatry, but this teaching remains in the LDS scripture and doctrine to this day. He does not give God the Glory and Power that He deserves. He has lowered God's Name. This teaching is extremely offensive to me and it makes me extremely sad. I can no longer support this man.
A few more quotes on the subject...
Doctrines of Salvation by Joseph Fielding Smith, v1, p. 10-12
Father and Son are resurrected men with physical bodies. Holy Ghost is a separate man with a spiritual body. Three totally separate Gods. God is married. Other Gods for other worlds.
Articles of Faith, p. 421 and 466-467
"Jesus Christ is the Son of Elohim both as spiritual bodily offspring; that is to say, Elohim is literally the Father of the spirit of Jesus Christ and also of the body in which Jesus Christ performed his mission in the flesh,"
History of the Church 6:474
"I have always declared God to be a distinct personage, Jesus Christ a separate and distinct personage from God the Father, and that the Holy Ghost was a distinct personage and a Spirit: and these three constitute three distinct personages and three Gods."
Apostle Bruce McConkie...
"...Father, Son, and Holy Ghost - comprise the Godhead... To us, speaking in the proper finite sense These are the Only Gods we worship. (Mormon Doctrine, p. 576-577)
LDS temple ceremony - Three Gods
... you will hear the voices of three persons who represent Elohim, Jehovah,
Elohim = God the Father
Jehovah = Jesus
(The Biblical meaning of Jehovah is God. Meaning Jehovah is LORD)
also see Reason 4
Michael = Adam
(Father of physical mankind) A.K.A. Michael the archangel
Jesus Christ is the same yesterday, today, and forever.
Therefore, if He was One God, is One God and always will be One God, then that will never change no matter what anyone, including a supposed prophet of God, preaches.
My unanswered questions were:
How could Joseph Smith, in his first vision, have seen two personages when there is clearly Only One God? Why are there three Gods in the LDS temple ceremony when there is clearly Only One God?
I was initially devastated when I received these answers, yet overjoyed to find the truth that there is Only One God and there is no way that God and Jesus can be Two different Personages or Gods!
