Priest's Prayer in Opus Angelorum

O Lord, God of Hosts! You made Your Angels winds, and Your Servants flames of fire! Send Your messenger spirits out in the power of Your Word, to call laborers into the harvest, to add their light to our words when we preach Your Gospel, and to call the faithful to the Wedding Feasts of the Lamb. Send forth Your Angels as flames of fire to purify our hearts, to teach us anew holy reverence before You as we stand at Your altar, as once Your Angel taught Moses from the Burning Bush!

May Your Angels strengthen us in all that is good, inflame our hearts with Your love, and with their flaming sword protect us and our flock from the roaring lion that roams about seeking the ruin of souls. Grant that by heeding their voice and following the light of their inspirations, we may escape all evil and come to the eternal home that You have prepared for us, so that together with Your Angels and Saints we may sing Your praises for ever and ever. Amen.
