See Advent Daily Prayer for the opening, closing, and canticle.
Psalm 117
Antiphon: O praise the Lord, all you nations.
O praise the Lord, all you nations,
acclaim him all you peoples!
Strong is his love for us;
he is faithful for ever.
Antiphon: O praise the Lord, all you nations.
Reading: 1 Thessalonians 5:23-24
May the God of peace make you perfect in holiness. May he preserve you whole and entire, spirit, soul, and body, irreproachable at the coming of the Lord Jesus Christ. He who calls us is trustworthy, therefore he will do it.
Pray either the Canticle of Zechariah or the Canticle of Mary. You can find them here.
