Micheal is not a being, it means 'resembling God'.
Certainly, it is the same as being a Messiah, for you are anointed with Godliness. It is also the same as Gabriel, for now you are empowered by God. It is the same as Rafael, for now your soul is healed in God. It is the same as Uriel, for the flame of God burns within you.
These are not distinct beings, they are ways of describing the enlightened state, now you are an angel - a messenger of God - for the enlightened ones every act and word manifests Truth.
Every enlightened being is Emmanuel - each are God among us, for each has dropped personal will, surrendered themselves to the will of God, now it is only God which resides within them.
How strange that Emmanuel is not considered an angel by the Christians, yet the others are Archangels, the heavenly hierarchy. There is no difference, just different aspects of the same state. That state is commonly referred to as enlightenment or illumination. It is every souls destiny: to return home.
