Interesting. Do you think we can conceive of what being a spirit creature is like very much? Some? Or not at all?
Also, what is meant by above angels in glory? Is it a reference to beatific vision?
Angels as I understand it, are static creatures. They can never be more than they were created to be. Thus Satan's jealousy of Adam. Mankind can become the children of God, so the difference in like between an heir and a servant.
