PRAISE the Lord, all ye nations: praise him, all ye peoples.
Great is the power of thine angels, O Christ! For being bodiless, they speed through the world guarding the churches with the strength which cometh from thee, O Master, and they intercede on behalf of the whole world.
FOR his mercy hath been abundant toward us: and the truth of the Lord endureth for ever.
O ye Powers, Authorities, Angels, Archangels, Seraphim and Thrones, Principalities and Dominions, Cherubim of the inexpressible glory and the perfect wisdom, intercede now on behalf of the whole world.
Glory be to the Father, and to the Son, and to the Holy Spirit.
Both now and for ever, and to the ages of ages.
HAVING obtained great benefits from thee, O Immaculate Lady, with the angels we honour thy child, who from the deepest compassion deigned to be born from thy womb, and make the human race anew.
