No, Jesus and Michael the Archangel are not the same. Jesus is God in flesh, but Michael the Archangel is an angel which is a created being.
- Daniel 10:13, ““But the prince of the kingdom of Persia was withstanding me for twenty-one days; then behold, Michael, one of the chief princes, came to help me, for I had been left there with the kings of Persia.”
- Jude 9, “But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him a railing judgment, but said, “The Lord rebuke you.”
In Jude 9, Michael would not pronounce a judgment against the devil. Instead, he said "the Lord rebuke you." If Michael and Jesus were the same and Jesus is God in flesh, then Michael would have had the authority to rebuke the devil. But, since Michael deferred to the Lord, Michael is not the Lord. Instead, Michael is in Archangel, a created being.
