Invocation of the Nine Choirs of Angels

September is dedicated to the Holy Angels. From Burning Lamp-stand:

According to ancient tradition, the angels are arrayed in a hierarchy of nine ranks or choirs, whose designations are drawn from Scripture.

O holy Angels, watch over us at all times during this perilous life.
O holy Archangels, be our guides on the way to heaven.
O heavenly choir of the Principalities, govern us in soul and body.
O mighty Powers, preserve us against the wiles of the demons.
O celestial Virtues, give us strength and courage in the battle of life.
O powerful Dominions, obtain for us dominion over the rebellion of our flesh.
O sacred Thrones, grant us peace with God and man.
O brilliant Cherubim, illuminate our minds with heavenly knowledge.
O burning Seraphim, enkindle in our hearts the fire of charity. Amen.
