Synaxis of the Archangel Michael & the other Bodiless Powers: Gabriel, Raphael, Uriel, Salaphiel, Jegudiel, & Barachiel

Reading from the Synaxarion:

All the Angels, according to the Apostle Paul, are ministering
spirits, - sent forth to minister to them who shall be heirs of salvation
- (Heb. 1:14). God set them as overseers of every nation and
people, and guides to that which is profitable (Deut. 32:8); and while
one Angel is appointed to oversee each nation as a whole, one is also
appointed to protect each Christian individually. He commands them to
guard them that hope on Him, that nothing should harm them, neither
should any evil draw nigh to their dwelling (Ps. 90:10-12). In the
Heavens they always behold the face of God, sending up to Him the
thrice-holy hymn and interceding with Him in our behalf, seeing they rejoice
over one sinner that repents (Esaias 6:2-3; Matt. 18:10; Luke 15:7).
In a word, they have served God in so many ways for our benefit,
that the pages of Holy Scripture are filled with the histories
thereof. It is for these reasons that the Orthodox Catholic Church,
wisely honouring these divine ministers, our protectors and guardians,
celebrates today the present Synaxis that is, our coming together in
assembly for their common feast to chant their praises, especially for the
Archangels Michael and Gabriel, who are mentioned in the Scriptures by name.
The name Michael means "Who is like God?" and Gabriel means "God
is mighty." The number of Angels is not defined in the divine
Scriptures, where Daniel says that thousands of thousands ministered before
Him, and ten thousands of ten thousands attended upon Him -(Dan.
7:10). But all of them are divided into nine orders which are called
Thrones, Cherubim, Seraphim, Dominions, Powers, Authorities,
Principalities, Archangels, and Angels.

Apolytikion in the Fourth Tone
O Commanders of the Heavenly Host, we the unworthy beseech you,
that through your entreaties you will fortify us, guarding us in the
shelter of the wings of your ethereal glory, even as we fervently bow
before you crying: "Deliver us from all danger, as Commanders of the
Powers on high! "

Kontakion in the Second Tone
Chief Commanders of God; ministers of divine glory; guides for men and
leadership of the Incorporeal; as Chief Commanders of the Incorporeal, plead
for our welfare and for great mercy.
