Doug the human is resistant to the notion that the only appropriate Christmas greeting is “Merry Christmas“, and he prefers and uses “Wishing you a blessed Christmas“.
Compare:
merry = cheerful and lively;
blessed = made holy; consecrated.
Seriously, which word better defines the significance of the birth of the Christ Child? Make your choice but consider this: the commercialism of Christmas is the war on this holy day, not some catch phrase you don’t like as well as another.
