Praying in the name of Michael the archangel instead of Jesus
Similarly, the name Jesus Christ is used in prayer to address his role as a redeemer and saviour, whereas the name Michael the archangel has a different purpose as his role as a prince and a warrior and is not used by believers while praying.
Sounds like the description of one man, two distinct personalities/beings. The type of description used to explain the trinity. Does Jesus/Mike have two heads? ;-)
