Many non-Adventist members of Christian denominations claim that the title of Michael the Archangel used by Ellen White is a direct challenge to Christ's deity - and a reiteration of the Jehovah's Witnesses' position that Jesus is a created being, and not equal to the Father.
To reply to this objection, a deep study of the title "archangel" in a good quality lexicon will effectively refute this objection. The word "archangel" comes from the Greek archon, meaning chief, or commander in chief. Any good lexicon will indicate several meanings of the Greek word above. The correct translation for "archangel" is commander of the angels, or commander -in-chief of the same. Thus the title of Michael the Archangel is not in any way, shape, or form designed to deny or diminish the deity of Jesus Christ. Michael means "Who is like God?" in Hebrew - and only Jesus can answer this question - as He is the express image of the Father, and the fullness of the Godhead.
Furthermore, God revealed Himself many times to Moses, Elijah, and other prophets as the ANGEL OF THE LORD, throughout the books of Genesis, Exodus, and other Old Testament books. Thus God Himself had assumed form of an angel while retaining His omnipotence and Deity. Thus we can say that the term "Michael the Archangel" is used in the same sense as the "Angel of the Lord" - that God Himself can assume the form of an angel in order to communicate closely with man on a personal, intimate level, as He did to Moses.
It is this Michael the Archangel, or the Angel of the LORD, that is mentioned in the twelfth chapter of Daniel, verses 1 and 2:
"And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book [the Lamb's book of life - Rev. 21:27].
"And many of them that sleep in the in the dust of the earth shall awake, some to everlasting life, and some to everlasting contempt."
After examining the above evidence, we can conclude that Michael and Christ are one and the same person.
