One of Biggest lies Mormon leaders teach

In Marvelous Work and A Wonder, Le Grand Richards Page 18 under the heading John’s Testimony of the Personality of God Says “This accords also with the report of John’s baptism of Jesus:   16 When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. 17 And suddenly a voice came from heaven, saying, “This is My beloved Son, in whom I am well pleased.”   Here each of the three members of the Godhead are distinctly and separately mentioned; (1) Jesus coming up out of the water; (2) the Holy Ghost descending like a dove; (3) the voice of the Father from heaven expressing his love and approval of his beloved Son. How could one possibly believe these three to be one person without body or form?
  President Gordon B. Hinckley explained why he also could not believe in the Trinity: The world wrestles with the question of who God is, and in what form He is found. Some say that the Father and the Son and the Holy Ghost are one. I wonder how they ever arrive at that. How could Jesus have prayed to Himself when he uttered the Lord’s Prayer? How could He have net with Himself when He was on the Mount of Transfiguration? No. He is a separate being. God, our Father, is one. Jesus Christ is two. The Holy Ghost is three. And these three are united in purpose and in working together to bring to pass the immortality and eternal life of man.’ ONE GOD The above comments are clearly antithetical   James Talmage states: “This [the Trinity] cannot rationally be construed to mean that the Father, the Son and the Holy Ghost are one in substance and person” (A Study of the Articles of Faith, p.40)
. Hugh B. Brown, The Abundant Life, p.313   Surely this was not ventriloquism where Christ was speaking to and of himself. It was the Father introducing His Son. In this case, the members of the Holy Trinity manifested themselves, each in a different way, and each was distinct from the others. A similar event occurred on the Mount of Transfiguration when members of the Godhead were distinguished in the presence of Moses and Elias, and Peter, James, and John.
What’s interesting about all these statements is that Le Grand Richards, Gordon B. Hinckley, James Talmage, Hugh B. Brown and other leaders like Jeffrey R Holland lie about the Orthodox view of the Godhead and pin modalism to Orthodox Christianity and our belief of the Trinity.
Notice how we believe the teaching they try to say we believe is considered a heresy and are called modalism and monarchism
Trinity 1 X 1 X 1 = 1 ONE GOD    Mormonism 1 + 1  +1 = 3 gods

Notice from reputable dictionaries  and encyclopedias we believe Three separate and distinct persons represent the ONE GOD God- Godhead- Substance- Essence- Being [ all Synonyms ] The doctrine of the Trinity in the godhead includes the three following particulars, viz. (a) There is only one God, one divine nature; (b) but in this divine nature there is the distinction of Father, Son, and Holy Ghost, as three (subjects or persons); and (c) these three-have equally, and in common with one another, the nature and perfection of supreme divinity. It was the custom in former times for theologians to blend their own speculations and those of others with the statement of the Bible doctrine. It is customary now to exhibit first the simple doctrine of the Bible, and afterwards, in a separate part, the speculations of the learned respecting it.

TRINITY The coexistence of the Father, the Son, and the Holy Spirit in the unity of the Godhead (divine nature or essence). The doctrine of the trinity means that within the being and activity of the one God there are three distinct persons: Father, Son, and Holy Spirit. Although the word trinity does not appear in the Bible, the “trinitarian formula” is mentioned in the Great Commission (Matt 28:19) and in the benediction of the apostle Paul’s Second Epistle to the Corinthians (2 Cor 13:14). (from Nelson’s Illustrated Bible Dictionary, Copyright © 1986, Thomas Nelson Publishers) Trinity used to express the doctrine of the unity of God as subsisting in three distinct Persons. This word is derived from the Gr. trias , first used by Theophilus (A.D. 168 A.D. – 183 A.D.), or from the Lat. trinitas, first used by Tertullian (A.D. 220 A.D.), to express this doctrine. The propositions involved in the doctrine are these: 1. That God is one, and that there is but one God (Deut 6:4; 1 Kings 8:60; Isa 44:6; Mark 12:29,32; John 10:30). 2. That the Father is a distinct divine Person (hypostasis, subsistentia, persona, suppositum intellectuale), distinct from the Son and the Holy Spirit. 3. That Jesus Christ was truly God, and yet was a Person distinct from the Father and the Holy Spirit. 4. That the Holy Spirit is also a distinct divine Person.
