Exusiai/Origin

Powers or Authorities ''' '''

The "Powers" (lat.  potestas  (f), pl.  potestates ), or "Authorities", from the Greek  exousiai , pl. of  exousia  (see Greek root in Eph 3:10), appear to collaborate, in power and authority, with the Principalities (Rulers).

The Powers are the bearers of conscience and the keepers of history. They are also the warrior angels created to be completely loyal to God. Some believe that no Power has ever fallen from grace, but another theory states that Satan was the Chief of the Powers before he Fell (see also Ephesians 6:12). Their duty is to oversee the distribution of power among humankind, hence their name.

Paul used the term  rule  and  authority  in Ephesians 1:21, [9 ] and  rulers  and  authorities  in Ephesians 3:10. [10 ] He may have been referring to the rulers and authorities of humanity, instead of referring to angels.
