"The word of God has provided nine explanatory designations of the heavenly beings... the first group is forever around God and is said to be permanently united with Him ahead of any of the others and with no intermediary. Here there are the most holy 'thrones' and the orders said to possess many eyes and many wings, called in Hebrew the 'cherubim' and 'seraphim'... The second group... is made up of 'authorities,' 'dominions,' and 'powers.' And the third, at the end of the heavenly hierarchies, is the group of 'angels,' 'archangels,' and 'principalities.'"
