One interesting custom for Epiphany is for families to ask God's blessing on our own homes. The Catholic tradition calls for parents or homeowner to mark, with blessed chalk, the main entrance door with the initials of the Magi and a code of the current year. This year's mark will be:

20 + C + M + B + 25

The numbers stand for the year in which the blessing is inscribed (2025). The letters stand for the names traditionally given the Magi who found the Christ Child:  Caspar, Melchior, and Balthazar. The crosses stand for Christ. They are also an abbreviation for the Latin blessing: Christus mansionem  benedicat, or "Christ bless this dwelling." Blessed chalk will be available after masses the weekend of January 4-5.

Gather your family at the main entrance to your home. 

All make the sign of the cross.

Parent or Homeowner:           "Let us praise God, who fills our hearts and homes with peace.                                   
                                                  Blessed be God forever."

Family/others:                         "Blessed be God forever."

Parent/Homeowner or reader:  (reading from Sacred Scripture) "And behold, the star that they had seen at its rising preceded                                                             them, until it came and stopped over the place where the child was. They were overjoyed at                                                                 seeing the star, and on entering the house they saw the child with Mary his mother. They                                                                     prostrated themselves and did him homage. Then, opening their treasures, they offered him gifts,                                                         gold and fankincense and myrrh."                     ― Matt 2:10-11

Parent/Homeowner imparts the blessing:  "Lord God of heaven and earth, You revealed Your only begotten Son to every nation                                                                             by the guidance of a star. Bless this house and all who inhabit it.  Fill them with the                                                                               light of Christ, that their concern for others may reflect Your love. We ask this though                                                                             Christ, our Lord."

Family/others:                                                 "Amen."

Then the parent/homeowner sprinkles holy water on those gathered and sprinkles it about the home.
