Evidence the SDA teaches Jesus is Michael

Some who are Seventh Day Adventist, sympathetic, or just uneducated about them believe they do not officially teach that Michael the Archangel is Jesus Christ. [As I mentioned several times before Jesus=Michael was a common Protestant doctrine among Calvinists and some Baptists until the 19th century] In a sense, this is true since their official website will you see very little about the Archangel being Jesus. I did find this:

Even before time on Earth began, the universe was engaged in a terrible conflict. John, the last living disciple of Jesus, described this conflict from what he saw in a vision while a prisoner on the island of Patmos. "There was war in heaven," he said. "Michael [another name for Jesus] and his angels fought against the dragon [Satan], and the dragon and his angels fought back" (Revelation 12:7).--A Lesson from History, Rodney Woods  [emphasis mine]

This is only a reference in passing. For more definitive proof the SDA states White is a prophet and her interpretation of the Bible is to be used since it was inspired by God. We see their official statement on Methods of Bible Study under Methods of Bible study 4.l says:

l.          Seventh-day Adventists believe that God inspired Ellen G. White. Therefore, her expositions on any given Bible passage offer an inspired guide to the meaning of texts without exhausting their meaning or preempting the task of exegesis (for example, see Evangelism, 256; The Great Controversy, 193, 595;Testimonies, vol. 5, pp. 665, 682, 707-708; Counsels to Writers and Editors, 33-35). --Methods of Bible Study: Bible Study: Presuppositions, Principles, and Methods, 4.l (Methods of Bible Study) [Official statement]

The preamble of this statement says:

This statement is addressed to all members of the Seventh-day Adventist Church with the purpose of providing guidelines on how to study the Bible, both the trained biblical scholar and others. --Methods of Bible Study, 1. Preamble

Also, at the bottom of the statement on the webpage says:

This statement was approved and voted by the General Conference of Seventh-day Adventists Executive Committee at the Annual Council Session in Rio de Janeiro, Brazil, October 12, 1986

Their official Church Manual under their 28 Fundamentals also states about Ellen White:

"One of the gifts of the Holy Spirit is prophecy. This gift is an identifying mark of the remnant church and was manifested in the ministry of Ellen. G. White . As the Lord's messenger, her writings are a continuing and authoritative source of truth which provide for the church comfort, guidance, instruction, and correction. They also make clear that the Bible is the standard by which all teaching and experience must be tested. (Joel 2:28, 29; Acts 2:14-21; Heb. 1:1-3; Rev. 12:17; 19:10.)."--Chapter 14: Fundamental Beliefs of the Seventh-Day Adventists, 18. The Gift of Prophecy, page 162. Seventh-Day Adventist Church Manual, Revised 2010. 18th edition. [pdf] [A smaller PDF of the relevant fundamental beliefs are found here]

The Adventists state this statement was lead by the Holy Spirit, but admit the Spirit might later cause them to better express their beliefs:

Seventh-day Adventists accept the Bible as their only creed and hold certain fundamental beliefs to be the teaching of the Holy Scriptures. These beliefs, as set forth here, constitute the church's understanding and expression of the teaching of Scripture. Revision of these statements may be expected at a General Conference Session when the church is led by the Holy Spirit to a fuller understanding of Bible truth or finds better language in which to express the teachings of God's Holy Word."--Chapter 14: Fundamental Beliefs of the Seventh-Day Adventists, page 156. Seventh-Day Adventist Church Manual, Revised 2010. 18th edition. [pdf] [A smaller PDF of the relevant fundamental beliefs are found here]

So, its plainly clear that Seventh-Day Adventists must believe in the divine inspiration of Ellen G White's writings. (Interestingly. despite the SDA often saying the Catholic Church is the whore of Babylon, here they seem to make a church structure like the Catholic with Ellen White being the equivalent to the Pope, and the General Conference being equal to Ecumenical Councils,) Here is what the "prophetess" White says about Michael the Archangel [all writings are on an SDA website], remember according to the SDA her writings are "inspired" by God according to them:

The words of the angel, “I am Gabriel, that stand in the presence of God,” show that he holds a position of high honor in the heavenly courts. When he came with a message to Daniel, he said, “There is none that holdeth with me in these things, but Michael [Christ] your Prince.” Daniel 10:21. --The Desire of Ages, page 99 (1898) Ellen G White

Again: Christ is called the Word of God. John 1:1-3. He is so called because God gave His revelations to man in all ages through Christ. It was His Spirit that inspired the prophets. 1 Peter 1:10, 11. He was revealed to them as the Angel of Jehovah, the Captain of the Lord’s host, Michael the Archangel.--Patriarchs and Prophets, Page 761. (1890) Ellen G White

Moses passed through death, but Michael came down and gave him life before his body had seen corruption. Satan tried to hold the body, claiming it as his; but Michael resurrected Moses and took him to heaven. Satan railed bitterly against God, denouncing Him as unjust in permitting his prey to be taken from him; but Christ did not rebuke His adversary, though it was through his temptation that the servant of God had fallen. He meekly referred him to His Father, saying, “The Lord rebuke thee.”--Early Writings, Page 164, Ellen G White [statement also found in The Story of Redemption, Page 206]

Michael, or Christ, with the angels that buried Moses, came down from heaven,--The Truth About Angels, Page 104, Ellen G White

 We see that since the Seventh-Day Adventists regard Ellen G White as a prophet with her writings inspired and "authoritative truth," and those writings teach Jesus is Michael, that logically this would make official Adventists doctrine to be Jesus is Michael.

Before the 7th Day Adventists said Jesus is Michael-Baptists did

Today, there are only two prominent Protestant sects that claim Jesus is Michael--the Jehovah Witness and the Seventh Day Adventists.  The JW's seeming to have had their beginnings in the SDA.  Concerning their Jesus is Michael doctrine, I first got informed of this from reading an article on articulifidei about a years ago. I have found more on Baptists teaching this.  In fact, Miller, who was a forerunner to the Adventists and really started the whole End of the World craze--was a Baptist and published his stuff in Baptist magazines. But anyway, here is the writings of a 18th century Reformed Baptist commentary, John Gill, of course reformed is just fancy talk for Calvinist (as it tends to be), the only real difference between a reformed baptist and a Calvinist is a reformed baptist tends to reject infant baptism. Anyway, John Gill, long before the Seventh Day Adventists and their barell of heresies, conspiracy theories, slander and misinformation said this:

Michael and his angels fought against the dragon:
by whom is meant not a created angel, with whom his name does not agree, it signifying "who is as God"; nor does it appear that there is anyone created angel that presides over the rest, and has them at his command; though the Jews seem to imagine as if the angels were ranged under several heads and governors, of whom they make Michael to be one; --John Gill's Exposition of the Bible, Revelation 12:7

And at that time shall Michael stand up
The Archangel, who has all the angels of heaven under him, and at his command, the Son of God, our Lord Jesus Christ; who is as God, as the name signifies, truly and really God, and equal in nature, power, and glory, to his divine Father: "he shall stand up"; which is not to be understood of his incarnation, or manifestation in the flesh, for this refers to times long after that; yet neither of his personal appearance in the clouds of heaven, and standing upon the earth in the latter day; but of his spiritual presence among his people, and protection of them, and continuance with them: this respects the spiritual reigns of Christ, the Lamb's standing upon Mount Zion, and the 144,000 with him, ( Revelation 14:1 ) , and this will be at that time, when the eastern antichrist, the Turk, will be destroyed; for the words are closely connected with the last verse of the preceding chapter; and when also the western antichrist, the pope of Rome, will come to his end; for, as they rose, so they will fall, much about the same time; and then Christ will rise and stand up, as the glorious Head of the church, and as a triumphant Conqueror over all his enemies, and take to himself his great power, and reign, and that kingdom which of right belongs to him. The great Prince which standeth for the children of thy people;-John Gill's Exposition of the Bible, Daniel 12:1

Ofcourse, Gill could not end his heresies with his belief in limited atonement, or confusing an Archangel for the Lord, he had to also claim the Pope is the antichrist (of the west). 

We also see another Calvinist work--the Genevah study bible calling Michael Jesus/God:

(i) Even though God could by one angel destroy all the world, yet to assure his children of his love he sends forth double power, even Michael, that is, Christ Jesus the head of angels.--Daniel 10:13 Geneva study bible

Regardless, Calvinists and Baptists tend to have an adverse reaction when show this doctrine was taught by a Reformed Calvinist long before people like Ellen G White or Charles Russell.
