My family had a missalette with prayers for the weeks of Advent to be said at the table before meals. Thanks to the power of Google, here they are. I offer my own version here:
Prayer over the Advent Wreath
Our help is in the name of the Lord. Who made heaven and earth. Let us pray. O God, by Your word all things are made holy. Pour forth Your blessing on this wreath and grant that we who use it may prepare our hearts for the coming of Jesus and that we may receive abundant graces. We ask this through Christ our Lord. Amen.
First Week of Advent (Reading: Luke 21:34-36)
May this light remind us of Jesus, who is the true light of the world. Let us call upon him whose coming we await, for he is: God from God, Light from Light, True God from True God. Amen.
Second Week of Advent (Reading: Luke 3:1-6)
Father, help us to prepare the way of Jesus, the light of the world. May we who believe he will come again serve You today and every day. Let us proclaim this mystery of our faith: Christ has died, Christ is risen, Christ will come again. Amen.
Third Week of Advent (Reading: Luke 3:10-18)
Lord, we ask you to penetrate the darkness of our minds so that, filled with your brightness, we may rejoice in your coming as we say: Blessed be God forever. Amen.
Fourth Week of Advent (Reading: Luke 1:39-45)
Lord, hurry and come to us. May your light shine in our lives, so that we may be freed from sin. Protect us from all anxiety as we wait in joyful hope for your coming as our Savior: For the kingdom, the power, and the glory are yours, now and forever. Amen.
