What scripture do people that believe Michael was JESUS use to come up with that.
Those were posted somewhere in this thread.
VIII. Summary of the Evidence
1. Terms used concerning Christ are similar to those used or Michael: (a) of Christ, as "Prince of princes," as "prince of the host," as "Messiah the Prince," and as the "Prince of life"; (b) of Michael, as "your prince," and as the "great prince."
2. As archangel is used of Michael, so is archegos and archon used of Christ. Thus: Christ is the archegos—the "captain", (Heb. 2:10); the "author" (Heb. 12:2); the "Prince" (Acts 3:15).

3. The beginning of the great controversy between Christ (Michael) and Satan is seen in Revelation 12:7-10.
4. Michael exercises the same prerogative as does Jehovah when He says to Satan, "The Lord rebuke thee."
5. Michael is equated with Christ by many Bible scholars.
From the foregoing it will be seen that our concept of Michael, as just another title for the Lord Jesus Christ, is vastly different from the views of others who teach that Michael is merely a created, angelic being and not the Eternal Word of God. In direct contrast to such a depreciating Christology, Seventh-day Adventists hold that Jesus is "very God of very God, of the same substance as the Father"—coequal, coexistent, and coeternal with God the Father. We believe that there never was a time when Christ was not. He is God forevermore, His life being "original, unborrowed, underived."
