[From the Liturgy appointed for this day]
Bless the Lord, O you his angels, you mighty ones who do his word, obeying the voice of his word!
Everlasting God, You have ordained and constituted the service of angels and men in a wonderful order. Mercifully grant that, as Your holy angels always serve and worship You in heaven, so by Your appointment they may also help and defend us here on earth; through Your Son, Jesus Christ, our Lord...
He will command his angels concerning you to guard you in all your ways.
Bless the Lord, O my soul, and all that is within me, bless his holy name!
Alleluia! They conquered him by the blood of the Lamb and the word of their testimony , for they loved not their lives even unto death. Alleluia!
It is truly good, right, and salutary that we should at all times and in all places give thanks to You, holy Lord, almighty Father, everlasting God, through Jesus Christ, our Lord. Through Him Your majesty is praised by all the holy angels and celebrated with one accord by the heavens and all the powers therein. The cherubim and seraphim sing Your praise, and with them we laud and magnify Your glorious name, evermore praising You and saying: Holy, holy, holy...
