God our Father,
in a wonderful way you guide the work of angels and men.
May those who serve you constantly in heaven
keep our lives safe from all harm on earth.
Grant this through our Lord Jesus Christ, your Son,
who lives and reigns with you and the Holy Spirit,
one God, for ever and ever.
(from the Christian prayer book, Liturgy of the Hours, for September 29, Feast day of Michael, Gabriel and Raphael, Archangels).
Important! Be sure to notice that this prayer is directed to God, not to the angels. Anything and everything that angels do to assist humans is at the behest of God and God alone.
