Michael - Mikhail

"Questions frequently arise in Christian circles about the true identity of the mysterious biblical character known as Michael, sometimes called "Michael the archangel" and "Michael the Great Prince." Some claim that Michael is the highest of the heavenly angels, one of the covering cherubs, or a special messenger like Gabriel. And therefore, he is a created being. Others, such as Bible commentator Matthew Henry, assert that Michael is simply another of the many names for Jesus Himself. Can we know the real identity of this mysterious being? Obviously, the key to deciphering this puzzling question is found in the Scriptures. "For precept must be upon precept, precept upon precept, Line upon line, line upon line, Here a little, there a little" Isaiah 28:10.

A quick look in a Bible concordance reveals that there are 15 references to the name Michael in Scripture. Ten of these are simply people named Michael. In fact, the entry for "Michael" in the lexicon a Greek and/or Hebrew dictionary states, "The name of an archangel and nine Israelites." It is the identity of Michael, the archangel and prince, mentioned in the last five references that we seek in this important study. 

The first three of these references to Michael are in the Old Testament book of the prophet Daniel. The last two are mentioned in the New Testament books of Jude and Revelation. With an honest study and comparison of these and other verses, clues quickly emerge that lead us to an inescapable conclusion of Michael's true identity He is none other than Jesus—He is not a created angel or cherub, but this name is another of the many grand titles for God's eternal Son! 

At first glance, the Old Testament appears to portray Michael as a prince, and the New Testament describes Him as an archangel. But by looking at other related Scriptures where similar language and wording are used, we will see an interesting pattern emerge. Warning

Before you proceed any further, please carefully read and digest this next thought. Because the word "angel" means messenger, it is used very freely and broadly in Scripture. Sometimes, men are called angels in the Bible 1 Samuel 29:9 Galatians 4:14. And sometimes angels are called men Genesis 32:24. And in other places, as will be soon shown, God Himself is identified as an angel! Of course, even angels are called angels.

Typically, when a person thinks of an angel, they picture one of the many levels of winged, ministering spirits known as angels, seraphim, or cherubim. Unlike Jesus, these celestial beings are created. There are some cults that teach that Jesus, before His earthly incarnation, was really just a powerful angel that had a feud with His wayward fellow angel Lucifer. In turn, this means that Jesus is a created being who has been promoted by the Father and therefore not the eternal God as Christians accept. This study categorically rejects that view. Jesus is, and always has been, God's eternal Son and indeed God Himself. Any comparison made to Jesus as an angel in this study is simply in the classical sense as a greatest messenger of salvation and is in no way intended to diminish from His eternal divinity.

Maybe the key is in the name

First, let's consider the meaning of some words and names. In the Greek New Testament, the word "angel" means "messenger," and "arch" means "chief, principle, greatest, or highest." So "archangel" simply means "highest or greatest messenger." The Hebrew name "Michael," found in the Old Testament, means "who is like God" or sometimes it forms a question: "Who is like God?" So the title Michael the archangel can be translated as "The greatest messenger who is God." Whether this name is a question, statement, or a challenge will be clear by further study. One angel did profess to be like God. That covering cherub fallen from the heavenly courts is Lucifer, who became the devil or Satan, by claiming to "be like the most High" Isaiah 14:14. In Revelation 12:7, Satan is opposed by "Michael and his angels" and is cast out of heaven."
