Chalk the Door – Epiphany House Blessing
20 C+M+B 20
“Christus mansionem benedicat”
The equation is written to be the first two digits of the year,
followed by the initials C, M, and B,
followed by the last two digits of the year.
Each portion is split by plus signs.
For this year, the equation would be written as
“20 + C + M + B + 20.”
The chalking holds two meanings.
The C, M and B, refer to the traditional names
of the Magi: Caspar, Melchior and Balthasar.
The letters also stand for the Latin phrase
“Christus mansionem benedicat” which means
“May Christ bless the house.”
The plus signs represent the cross
and the 20 and 20 simply refer to the year.
