Life and strength of all Thy servants, Brightness of the Father???s light; Men with angels, earth with Heaven, In Thy praise their songs unite. Thousand thousand warrior princes In Thine angel army stand; Flames the victor Cross before them, Grasped in Michael???s dauntless hand. Hurling back from Heav???n the rebels With the lifting of his sword, In the might of God he tramples On the dragon???s head abhorred. Lord of angels, Christ, we pray Thee, Bid them aid us in our strife, Chase afar the hosts of evil, Till we reach the land of life. God the Father, God immortal, God the Son, for us Who died, God the Comforter, the Spirit, Evermore be glorified!
