Chalk your front door, or a nearby wall, for Epiphany.
20 + C + M + B + 20
The first and last numbers refer to this new year. The letters C M B are the first letters of the traditional names for the three Kings (Casper, Melchior and Balthazar), and they also represent the first letters of a prayer in Latin:-
Christus Mansionem Benedicat
May Christ bless this dwelling
This is a beautiful prayer that can be prayed to bless your home:-
Bless this home and all who live here.
Fill us with the light of Christ,
so that our concern for others may reflect your love.
Bless all our comings and goings this year and all who visit;
in Jesus name.
