The Archangel Michael is the chief angel, the head of the holy host of Angels and Archangels. "Archangel Michael" includes five words:
arch - senior
angel - messenger
mi - who
ka - like
el - God
The literal translation of the name, "Who is like God?", suggests a questioning intonation. Thus, the name "Michael" means "no one is equal to God".
O Lord God, Great and Eternal King! Send, O Lord, Thy Archangel Michael to help Thy servant (name), and to deliver me from all my enemies, visible and invisible. O Archangel Michael, angel of the Lord and vanquisher of demons! Suppress all my combatants, make them meek as sheep, and disperse them like dust before the wind. O great Michael, Archangel of the Lord, six-winged high prince, leader of the heavenly host, the Cherubim and the Seraphim! O kind Archangel Michael, be my helper in all offenses, sorrows and woes, in the desert, at the crossroads, be a safe haven on rivers and seas. Deliver me, O great Archangel Michael, from all the temptations of the demons, when they hear me, thy sinful servant (name), praying to thee, and calling upon thee, and entreating thy holy name: hasten to assist me and heed my prayer. O great Archangel Michael! Vanquish all my opponents by the power of the Holy and Life-giving Heavenly Cross of the Lord, by the prayers of the Most-holy Theotokos and the holy apostles, the holy prophet of God Elias, Saint Nicholas the wonder worker, Saint Andrew the fool-for-Christ, the holy great martyrs Nikitas and Eustace, the venerable fathers and holy hierarchs, martyrs, and all the heavenly host. Amen.
