The Order of Angels is a hierarchy of nine angelic choirs, each with its own purpose and role in the divine plan. The highest order is the SERAPH, which is a six-letter word meaning 'fiery serpent' or 'burning one'. The second highest order is the THRONES, a seven-letter word meaning 'seat of authority'. The third highest order is the SERAPHIM, an eight-letter word meaning 'the burning ones'. These three orders are the highest and most powerful of the angelic choirs.
