The use of the Christmas tree is relatively modern. Its origins are
found in the medieval mystery plays that depicted the tree of
paradise and the Christmas light or candle that symbolized
Christ, the Light of the world.

According to custom, the Christmas tree is set up just before Christmas
and may remain in place until the Solemnity of Epiphany.
The lights of the tree are illuminated after
the prayer of blessing.

In the home the Christmas tree may be blessed by a parent
or another family member, in connection with the evening
meal on the Vigil of Christmas or at another
suitable time on Christmas Day.

The leader makes the sign of the cross, and all reply “Amen.”

The leader may greet those present in the following words:

Let us glorify Christ our light, who brings salvation and peace into our midst, now and forever.  R/. Amen.

In the following or similar words, the leader prepares those present for the blessing:

My brothers and sisters, amidst signs and wonders Christ Jesus was born in Bethlehem of Judea: his birth brings joy to our hearts and enlightenment to our minds. With this tree, decorated and adorned, may we welcome Christ among us; may its lights guide us to the perfect light.

One of those present or the leader reads a text of sacred Scripture, for example, Titus 3:4 (lines 4-7)  or Ezekiel 17:22  (lines 22-24 4; I will plant a tender shoot on the mountain heights of Israel.)

Reader: The Word of the Lord.   R/. Thanks be to God.

The intercessions are then said. The leader says:

Let us ask God to send his blessing upon us and upon this sign of our faith in the Lord.
R/. Lord, give light to our  hearts.

That this tree of lights may remind us of the tree of glory on which Christ accomplished our salvation, let us pray to the
Lord.
R/. Lord, give light to our  hearts.

That the joy of Christmas may always be in our homes, let us pray to the Lord.
R/. Lord, give light to our  hearts.

That the peace of Christ may dwell in our hearts and in the world, let us pray to the Lord.
R/. Lord, give light to our  hearts.

After the intercessions the leader invites all present to say the Lord’s Prayer.

Then the  leader says the following prayer with hands joined:

Lord our God,
we praise you for the light of creation:
the sun, the moon, and the stars of the night.
We praise you for the light of Israel:
the Law, the prophets, and the wisdom of the Scriptures.
We praise you for Jesus Christ, your Son:
he is Emmanuel, God-with-us, the Prince of Peace,
who fills us with the wonder of your love.

Lord God,
let your blessing come upon us
as we illumine this tree.
May the light and cheer it gives
be a sign of the joy that fills our hearts.
May all who delight in this tree
come to the knowledge and joy of salvation.
We ask this through Christ our Lord.

R/. Amen.

The lights of the tree are then illuminated.

The leader concludes the rite by signing himself or herself with the sign of the cross and saying:

May the God of glory fill our hearts with peace and joy, now and forever.
R/. Amen.

The blessing concludes with a verse from “O Come, O Come, Emmanuel”:

O come, thou dayspring, come and cheer
our spirits by thine advent here;
disperse the gloomy clouds of night
and death’s dark shadow put to flight.
Rejoice! Rejoice! Emmanuel
shall come to thee, O Israel.
