Advent and Christmas at HNOJ

Pope Benedict XVI said this in 2008 about Christmas Trees,
"With its loftiness, its green [color] and the lights in its branches, the Christmas tree is a symbol of life that points to the mystery of Christmas Eve. Christ, the Son of God, brings to the dark, cold, unredeemed world in which he was born, a new hope and a new splendor. If a man allows himself to be touched and enlightened by the splendor of the living truth that is Christ, he will experience an interior peace in his heart and will himself become an instrument of peace in a society that has so much nostalgia for reconciliation and redemption.”

USCCB on Christmas Trees:

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.

Patron Saint of Christmas Trees - St. Boniface
In one of the earliest stories relating to the Christmas tree, the eighth-century Catholic missionary, Saint Boniface, is said to have cut down an oak tree sacred to the pagan god Thor. An evergreen, fir tree grew in its place, which Boniface
said symbolized the everlasting nature of Jesus Christ.

Christmas Tree Blessing
Use the following blessing to bless your Christmas Tree at home. From the USCCB

When all have gathered, a suitable song may be sung.
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.
The leader says the 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”:
