The Epiphanytide practice of household blessing also serves to protect Christian homes from evil spirits until the next Epiphany Day, at which time the custom is repeated. This rite of blessing the home is led by a priest. If no priest is available, please use the following guide:
 

V: Peace be to our home.
R: And to all who dwell herein.

ANTIPHON
From the East came the Magi 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.

You then sprinkle holy water throughout the home.

Please bless, O Lord, almighty God this home that it be a shelter of health, chastity, self-conquest, humility, goodness, mildness, obedience to the commandments, and thanksgiving to God the Father, Son, and Holy Ghost. May this blessing remains for all time upon this dwelling and to all those who live herein. Through Christ our Lord.
R: Amen.

You then inscribe with blessed chalk the initials of the three kings over the lintel of the doors (especially the doors leading into the home), denoting the century and year on either side, for example: 22 † C † M † B † 23 The following prayer may then be said:

Hear us. O Holy Lord, Father Almighty, Eternal God, and send Thy Holy Angel from Heaven to watch over, cherish, protect, be with, and defend all who live in this house. I call upon Thy saints, Caspar, Melchior, and Balthazar, to protect this family and this home from every harm and danger, and I place the marks of their holy names over the doors of this home to remain there as a constant reminder to us and to all who enter here that this house is truly a house of the Lord.

O God, make the door of this house wide enough to receive all who need charity and companionship, narrow enough to shut out all envy, pride, and strife. Make its threshold smooth enough to be no stumbling block to children, nor to straying feet, but rugged and strong enough to turn back the Tempter’s power.

O God, make the door of this house the gateway to Thy eternal Kingdom, I ask these things in the name of Jesus Christ, Thy Son, Our Lord, Amen.
