The Investigative Judgment eradicates all assurance of salvation:
How solemn is the thought! Day after day, passing into eternity, bears its burden of records for the books of heaven. Words once spoken, deeds once done, can never be recalled. Angels have registered both the good and the evil. The mightiest conqueror upon the earth cannot call back the record of even a single day. Our acts, our words, even our most secret motives, all have their weight in deciding our destiny for weal or woe. Though they may be forgotten by us, they will bear their testimony to justify or to condemn (end of page 509 of The Great Controversy - Investigative Judgment starts on page 501). 

SDA doctrine says that Jesus is Michael the archangel:
In Jude 1:9, the SDA's Clear Word Bible says, "In contrast to these ungodly men is the Lord Jesus Christ, also called Michael, the archangel in charge of the entire angelic host. When He was challenged by Satan about His intentions to resurrect Moses, He didn't come against Satan with a blistering attack nor did he belittle him. He simply said, 'God rejects your claim to his body.'"
