Synaxis for the archangels

Commanders of the heavenly hosts,
we who are unworthy beseech you,
by your prayers encompass us
beneath the wings of your immaterial glory,
and faithfully preserve us who fall down and cry to you:
“Deliver us from all harm,
for you are the commanders of the powers on high!” –Troparion – Tone 4

We Christians invoke St Michael for protection from invasion by enemies and from civil war, and for the defeat of adversaries on the field of battle. He conquers all spiritual enemies.
