Deu 6:4  Hear, O Israel: The LORD our God is one LORD:

“Satan has long been preparing for his final effort to deceive the world. The foundation of his work was laid by the assurance given to Eve in Eden: "Ye shall not surely die." "In the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil." Genesis 3:4,5. Little by little he has prepared the way for his masterpiece of deception in the development of spiritualism. He has not yet reached the full accomplishment of his designs; but it will be reached in the last remnant of time. … Except those who are kept by the power of God, through faith in His word, the whole world will be swept into the ranks of this delusion.”GC 561

You ask what we teach about the Trinity. Inasmuch as we find no such expression in the Scriptures, we do not teach anything about it. But as to the Being of God,-the Godhead,-Divinity as revealed in the Father, the Word (the Son), and the Holy Spirit, we believe and teach just what the Bible says, and nothing else. No man can by searching find out God. No creature can understand the Almighty to perfection. The finite mind cannot comprehend infinity. Therefore, in discussions about the Trinity, about the nature of God, Christ, and the Holy Spirit, are manifestations of gross presumption. E.J Waggoner Present Truth Feb 6 1902

"It is an inescapable teaching of Scripture Adrian that Jesus is Yahweh. Therefore, we cannot entertain the grave error that you propose, that is that Jesus is the literal Son of Yahweh, born from Him at sometime in eternity past. He cannot be the son of Himself. He cannot be a literal son. It is true that He did become a son through His birth from the Virgin Mary but that has nothing whatever to do with the origin you claim for Him in eternity. Of course it is legitimate for Jesus to be called Son of God because of the Incarnation, but, there is no excuse whatever for calling Him the Son of God because of a supposed literal birth from God in eternity.  – Jesus is Yahweh and therefore cannot be the literal son of Yahweh.
