Are Mormon's/ LDS Members Believe in Polytheism or Monotheism?

Mom (or rather Kyle) asked me if our religion (The Church of Jesus Christ of Latter Day Saints) are Monotheistic or Polytheistic? I immediately said Monotheistic. Even though to my dad said I was right and in a way to my mom I was wrong, I didn't have enough information to back up my answer. So here I am, searching for the true answer. May God help me.


This is what I found so far:
* "The Only True God and Jesus Christ Whom He Hath Sent" By Jeffrey R. Holland
     ~ " We declare it is self-evident from the scriptures that the Father, the Son, and the Holy Ghost are separate persons, three divine beings."
     ~ " Our first and foremost article of faith in the Church of Jesus Christ of Latter Day Saints is 'We believe in God, the Eternal Father, and in His son, Jesus Christ, and in the Holy Ghost.' We believe these three divine persons constituting a single Godhead are united in purpose, in manner, in testimony, in mission. We believe Them to be filled with the same godly sense of mercy and love, justice and grace, patience, forgiveness, and redemption. I think it is accurate to say we believe They are one in every significant and eternal aspect imaginable except believing Them to be three persons combined in one substance, a Trinitarian notion never set forth in the scriptures because it is not true."
     ~ "In the year A.D.‍ 325 the Roman emperor Constantine convened the Council of Nicaea to address—among other things—the growing issue of God’s alleged “trinity in unity.” What emerged from the heated contentions of churchmen, philosophers, and ecclesiastical dignitaries came to be known (after another 125 years and three more major councils) ⁴ as the Nicene Creed, with later reformulations such as the Athanasian Creed. These various evolutions and iterations of creeds—and others to come over the centuries—declared the Father, Son, and Holy Ghost to be abstract, absolute, transcendent, immanent, consubstantial, coeternal, and unknowable, without body, parts, or passions and dwelling outside space and time. In such creeds all three members are separate persons, but they are a single being, the oft-noted “mystery of the trinity.” They are three distinct persons, yet not three Gods but one. All three persons are incomprehensible, yet it is one God who is incomprehensible."
     ~ "To whom was Jesus pleading so fervently all those years, including in such anguished cries as “O my Father, if it be possible, let this cup pass from me” ¹⁴ and “My God, my God, why hast thou forsaken me”? ¹⁵ To acknowledge the scriptural evidence that otherwise perfectly united members of the Godhead are nevertheless separate and distinct beings is not to be guilty of polytheism; it is, rather, part of the great revelation Jesus came to deliver concerning the nature of divine beings. Perhaps the Apostle Paul said it best: “Christ Jesus … being in the form of God, thought it not robbery to be equal with God.”
     ~ "Through the Holy Spirit of Truth, may we all‍ know “the only true God, and Jesus Christ, whom [He has] sent."

*The Fulness of the Gospel: The Nature of the Godhead, "The Fulness of the Gospel: The Nature of the Godhead", Ensign, Jan. 2006, 50–51
     ~ "Three Separate Beings: 'In common with the rest of Christianity,' Elder Oaks continued, 'we believe in a Godhead of Father, Son, and Holy Ghost. However, we testify that these three members of the Godhead are three separate and distinct beings. We also testify that God the Father is not just a spirit but is a glorified person with a tangible body, as is his resurrected Son, Jesus Christ. … In contrast, many Christians reject the idea of a tangible, personal God and a Godhead of three separate beings. They believe that God is a spirit and that the Godhead is only one God. In our view, these concepts are evidence of the falling away we call the Great Apostasy.' ²

      Not long after the deaths of the Savior’s New Testament Apostles, ideas from Greek philosophy began transforming plain and precious gospel truths. Conflicting doctrines regarding the nature of deity led Emperor Constantine to convene a churchwide council in Nicaea in A.D. 325. The resulting Nicene Creed eliminated the concept of deity as separate beings by declaring Jesus Christ to be “one substance with the Father.”

'Other councils followed,” Elder Oaks explained, “and from their decisions and the writings of churchmen and philosophers there came a synthesis of Greek philosophy and Christian doctrine. … The consequences persist in the various creeds of Christianity, which declare a Godhead of only one being.'" ³

     ^{~ "Divine Truth Restored: The truth concerning the nature of the Godhead was restored in the spring of 1820 when Joseph Smith entered the Sacred Grove. As he prayed, a pillar of light appeared, which he described as being “above the brightness of the sun. … When the light rested upon me,” he recorded, “I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!” (JS—H 1:16–17). Joseph learned during this vision, among other truths, that God the Father and His Son, Jesus Christ, are separate, glorified individuals and that we, as the Bible teaches, are created “in the image of God” (Gen. 1:27).}

President Gordon B. Hinckley has said, “The experience of Joseph Smith in a few moments in the grove on a spring day in 1820, brought more light and knowledge and understanding of the personality and reality and substance of God and his Beloved Son than men had arrived at during centuries of speculation.” ⁴

In 1843 Joseph Smith summarized what he had learned through direct revelation about the Godhead: “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 130:22).
