"I have always declared God to be a distinct personage, Jesus Christ a separate and distinct personage from God the Father, and the Holy Ghost was a distinct personage and a Spirit: and these three constitute three distinct personages and three Gods," (Teachings of Prophet Joseph Smith, p. 370)The Godhead consists of the three distinct personages and three gods.. The Father Son and Holy Spirit. The Father and Son have bodies of flesh and bones, while the Holy Spirit is a personage of spirit. Robert Millet A Different Jesus page 198The trinity is three separate Gods: The Father, the Son, and the Holy Ghost. "That these three are separate individuals, physically distinct from each other, is demonstrated by the accepted records of divine dealings with man," (Articles of Faith, by James Talmage, p. 35).Mark 12:28 And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all? 29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: "Very interesting the pre-1835 Joseph Smith agreed with Jesus2 Nephi 31:21 And now, behold, my beloved brethren, this is the way; and there is none other way nor name given under heaven whereby man can be saved in the kingdom of God. And now, behold, this is the doctrine of Christ, and the only and true doctrine of the Father, and of the Son, and of the Holy Ghost, which is one God, without end. Amen.Alma 11:44 Now, this restoration shall come to all, both old and young, both bond and free, both male and female, both the wicked and the righteous; and even there shall not so much as a hair of their heads be lost; but everything shall be restored to its perfect frame, as it is now, or in the body, and shall be brought and be arraigned before the bar of Christ the Son, and God the Father, and the Holy Spirit, which is one Eternal God, to be judged according to their works, whether they be good or whether they be evil.Mormon 7:7 And he hath brought to pass the redemption of the world, whereby he that is found guiltless before him at the judgment day hath it given unto him to dwell in the presence of God in his kingdom, to sing ceaseless praises with the choirs above, unto the Father, and unto the Son, and unto the Holy Ghost, which are one God, in a state of happiness which hath no end.The Testimony of Three WitnessesAnd the honor be to the Father, and to the Son, and to the Holy Ghost, which is one God.

Amen.Even at General Conference this was saidCOUNSEL GIVEN BY PRESIDENT CHARLES W. PENROSENow, some of our brethren have taken up quite a discussion as to the fulness of the everlasting gospel. We are told that the Book of Mormon contains the fulness of the gospel, that those who like to get up a dispute, say that the Book of Mormon does not contain any reference to the work of salvation for the dead and that there are many other things pertaining to the gospel that are not developed in that book, and yet we are told that the book contains "the fulness of the everlasting gospel." Well, what is the fulness of the gospel? You read carefully the revelation in regard to the three glories, Section 76, in the Doctrine and Covenants, and you find there defined what the gospel is. There God, the Eternal Father, and Jesus Christ, his Son, and the Holy Ghost, are held up as the three Persons in the Trinity—the one God, the Father, the Word, and the Holy Ghost, all three being one God. When people believe in that doctrine and obey the ordinances which are spoken of in the same list of principles, you get the fulness of the gospel for this reason: If you really believe so as to have faith in our Eternal Father and in his Son, Jesus Christ, the Redeemer, and will hear him, you will learn ail about what is needed to be done for the salvation of the living and redemption of the dead.(General Conference Report, April 1922, pp. 27-28.)
So why do Mormons reject Jesus, the Book of Mormon and Bible and cling to the words of post 1835 Joseph Smith
During Joseph Smith's post 1835 period he went to a full-blown polytheist
Book of Abraham
The Gods plan the creation of the earth and all life thereon—Their plans for the six days of creation are set forth.
7 And the Gods ordered the expanse, so that it divided the waters which were under the expanse from the waters which were above the expanse; and it was so, even as they ordered.
Mormons have always twisted scripture to justify polytheism, here's one that even one of there so-called Apostle gets right
James Talmage, a Mormon Apostle, said Psalm 82:6 is not about becoming gods.
"In Psalm 82:6, judges invested by divine appointment are called 'gods.' To this scripture the Savior referred in His reply to the Jews in Solomon's Porch. Judges so authorized officiated as the representatives of God and are honored by the exalted title 'gods.' Compare the similar appellation applied to Moses (Exo. 4:16; 7:1). Jesus Christ possessed divine authorization, not through the word of God transmitted to Him by man, but as an inherent attribute. The inconsistency of calling human judges 'gods,' and of ascribing blasphemy to the Christ who called Himself the Son of God, would have been apparent to the Jews but for their sin-darkened minds." (James Talmage, Jesus the Christ, p. 501). -- Mormons often quote Psalm 82:6 which Jesus quoted in John 10:30-34 to show that we can become gods.
Rather than them believing the truth from a Christian, perhaps they will believe it from their own apostle.
judge must act with impartiality and true justice, because even judges must stand someday before the Judge. Verses 6 and 7 warn human magistrates that they, too, must be judged: “I said, `You are gods; you are all sons of the Most High.' But you will die like mere men; you will fall like every other ruler.”
This passage is saying that God has appointed men to positions of authority in which they are considered as gods among the people. They are to remember that, even though they are representing God in this world, they are mortal and must eventually give an account to God for how they used that authority.
