Lucifer, being next to Christ the Son of God, in Heaven tried to usurp (assume) authority as the third being (person) of the Godhead, claiming that he should be included in the counsels of God the Father and His Son. In subtle little hints he suggested to the angels that his position of being the brightest, most beautiful, strongest and the leader of all the angels gave him the right to be in those counsels. He was defeated and cast out of Heaven along with his sympathizers. Now we see that Satan HAS usurped (assumed) that authority of the third being (person) of the godhead here on earth as it is in the teaching of the triune (trinity) god. Obviously this is a false god whose teaching will eventually lead the believer into reasoning that God the Father and the Son of God are NOT REALLY REAL, but are "metaphorical figures", "titles", or "three gods just deciding to role-play their parts" , all this for the salvation of man. Somewhere in eternity they got together and decided that one would be the Father, one would be the Son and one the Holy Spirit. Unfortunately, these are the exact quotes from our Church leaders, theologians and teachers. Our future ministers in this church are being taught this lie. We read in their books and sabbath school lessons "Although the word trinity cannot be found in scripture but....the concept can be found in 'subtle textual hints'" (Glimpses of our God, Lesson 1, page 6, January 2012.) If our Heavenly Father and His only begotten Son are not real, then our salvation is not real and we fall under 1John 2:22-24,
"Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. No one who denies the Son has the Father. He who confesses the Son has the Father also. Let what you heard in the beginning abide in you. If what you heard from the beginning abide in you, then you will abide in the Son and the Father."
This is why our Father sends three angels to warn us (Rev. 14:6). Embedded in that warning is the proclamation to worship the TRUE GOD who created the heavens and earth and seas. God is calling us to come out from following these FALSE DOCTRINES OF MAN (ROME) in which the trinity teaching is their foundational teaching. "Let him who have an ear hear" Our Father says of Jesus, "This is my beloved Son, with whom I am well pleased; LISTEN TO HIM". (Matt. 17:5) What did Jesus say? "This IS eternal life, that they KNOW thee the ONLY TRUE GOD, and Jesus Christ whom thou has sent." (John 17:3)
God has revealed to us through His servant what has actually happened. Read EARLY WRITINGS page 55-56, there in vision we see Satan moving in to take that assumed authority in the holy place of the sanctuary, posing as Christ, after Jesus went into the Holy of Holies in 1844. Some christians followed Jesus there while others stayed in the holy place. When God's people in the Holy of Holies by faith pray "My Father, give us Thy Spirit".... "Jesus BREATHES upon them the Holy Spirit. In that breathe was light, power and much love, joy and peace." We also see the other christians pray the same prayer, "Father, give us Thy Spirit." "Satan would then breathe upon them an UNHOLY INFLUENCE; in it there was light and much power, BUT NO sweet love, joy and peace. Satan's object was to keep them deceived and to draw back and deceive GOD"S CHILDREN."
I pray that our gracious Heavenly Father (the source of all) through His dearly beloved Son will open our eyes, as a church, in seeing and understanding the ONLY TRUE GOD and HIS SON and worship them as the angelic host in Heaven "worship HIM who sits on the Throne and the LAMB." AMEN!
