Identifying Michael as Jesus Christ is widely supported by reference to 1 Thessalonians 4:16. Paul there associates the Second Coming of Jesus with the voice of the archangel. The word archangel (Greek: archangelos, archangelou) appears only two times in the New Testament. In Jude 9 the archangel is named Michael, in 1 Thessalonians, the archangel is not named, but is present at the Second Coming. In both instances, the archangel is involved in the resurrection of the dead. It is a small step from there to the conclusion that the archangel Michael and Jesus Christ are one and the same person, although this is not explicit in 1 Thessalonians or Jude.

Further evidence for identifying the two is the fact that both Michael (Daniel 10:13, 21; Jude 9; Rev 12:7) and Jesus Christ (Matt 4:1-11; Rev 12:7-8) do battle with Satan. Michael is one of the chief princes (Dan 10:13—he is chief ruler in the Greek: archōnton tōn prōtōn), the great prince (Dan 12:1), and an archangel (Jude 9). Jesus Christ is king of kings and lord of lords (Rev 17:14; 19:16), the ruler of the kings of the earth (Rev 1:5). In Revelation 13:4, the worshipers of the sea beast (who is portrayed as a counterfeit of Christ) cry out, “Who is like the beast?” This cry echoes the name of Michael (Rev 12:7), which means, “Who is like God?” So there is significant evidence that at least some writers of the New Testament identified Michael with Jesus Christ.
