Over Epiphanytide there is a custom to bless the home with a prayer and chalking in the year and initials of the wise men who journeyed over a long distance to meet the Christ-child. This custom is about welcoming the Christ-child and the unknown visitor into your home.
Using the blessed chalk (I still have some if anyone local needs it), mark the lintel of your front door (or front porch step) as follows:
20 + C + M + B + 18 while saying:
The three Wise Men, Caspar, Melchior, and Balthazar followed the star of God’s Son who became human two thousand and eighteen years ago. May Christ bless our home and remain with us throughout the new year. Amen.
Then offer the following prayer:
Visit, O blessed Lord, this home with the gladness of your presence. Bless all who live or visit here with the gift of your love; and grant that we may manifest your love to each other and to all whose lives we touch. May we grow in grace and in the knowledge and love of you; guide, comfort, and strengthen us in peace, O Jesus Christ, now and forever. Amen.
