"For by him all things were created in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities.." E.S.V.
Possible areas for consideration:
Do we need to understand how thrones, dominions, rulers and authorities relate to each other to understand them individually? e.g. David sat on a throne [thronon] Luke 1:32. Are thrones senior to dominions so that David was able to appoint people to "dominions"?
An N.I.V. Study Bible footnote says that thrones, dominions, rulers and authorities are "an angelic hierarchy". MacArthur N.K.J.V. footnote agrees that "these are various categories of angels".
"death hath no more dominion [kyrieuei] over him", Romans 6:9. Is something which has dominion over something else necessarily a dominion?
Neither David's throne nor "death" [Romans 6:9] sound like angels to me.
How can the "by him all things were created in heaven and on earth" turn out to be just angels?
