Thank you for posting that information. This Sunday, our pastor will bless new crosses + fresh bottles of holy water and distribute these to the registered parishioners. The new cross will be hung by the front door. I will use your blessing ceremony with the fresh holy water to bless our house. Hopefully the temperature outside will rise above single digits :-0
The Blessing of Chalk and the Blessing of a Home
There is a difference between blessings given by a priest and the same blessings read by the father or some older member of the family when it is not possible to have the priest present. But it is a mistake to consider them without efficacy when the layman reads them. By our Baptism we have a share in Christ's Priesthood. If we are part of Christ in His Mystical Body, and He is High Priest, we share this with Him. Ours is not the same as the power of the consecrated priest, but it is our right and privilege to ask God's blessing on the things we use in daily life, and we should exercise this privilege often.
The Blessing of Chalk is usually given by a priest at church. The chalk is then distributed to the people, who take it home to use after the Blessing of the Home.
Blessing of Chalk
Verse (leader). Our help is in the name of the Lord.
Response (all). Who made heaven and earth.
V. The Lord be with you.
R. And with your spirit.
Bless, O Lord God, this creature chalk to render it helpful to men. Grant that they who use it in faith and with it inscribe upon the entrance of their homes the names of thy saints, Caspar, Melchior, and Balthasar, may through their merits and intercession enjoy health of body and protection of soul. Through Christ our Lord. Amen.
(Sprinkle chalk with holy water.)
If this blessing is not ordinarily given at church, perhaps it could be if enough parishioners requested it; at any rate, it may be read by the father or one of the grownups at home.
In some parishes it is a custom for the pastor to bless the homes of the parish from the church doorway, the people reading the words of the blessing at the same hour in their homes, and going in procession from room to room sprinkling the house with holy water. At the end of this procession, the father or other grownup writes over the front door with the blessed chalk:
20 + C + B + M + 09
Blessing of Homes on Epiphany
V. Peace be to this house.
R. And to all that dwell herein.
Antiphon: From the east the Magi came to Bethlehem to adore the Lord; and opening their treasures, they offered costly gifts: gold to the great King, incense to the true God, and myrrh in symbol of His burial. Alleluia
Now follows the reading of the Magnificat (Luke 1:46-55). The home is sprinkled with holy water, and following the Magnificat the antiphon is repeated: From the east. . . . Then the Our Father, silently.
V. And lead us not into temptation.
R. But deliver us from evil.
V. Many shall come from Saba
R. Bearing gold and incense.
V. O Lord, hear my prayer.
R. And let my cry come unto thee.
V. The Lord be with you.
R. And with thy spirit.
Let us pray. O God, Who by the guidance of a star didst this day reveal thy Sole-Begotten Son to the Gentiles, grant that we who now know thee by faith may be brought to the contemplation of thy heavenly majesty. Through the same Jesus Christ, thy Son, our Lord Who liveth and reigneth with thee in the unity of the Holy Spirit, God, forever and ever. Amen.
Responsory: Be enlightened and shine forth, O Jerusalem, for thy light is come, and upon thee is risen the glory of the Lord, Jesus Christ born of the Virgin Mary.
V. Nations shall walk in thy light, and kings in the splendor of thy birth.
R. And the glory of the Lord is risen upon thee.
Let us pray. Bless, O Lord, almighty God, this home that it be the shelter of health, chastity, self-conquest, humility, goodness, mildness, obedience to the commandments, and thanksgiving to God the Father, Son, and Holy Spirit. May blessing remain for all time upon this dwelling and them that live herein. Through Christ our Lord. Amen.
