One of the teachers at my daughter's school put this picture up on his Google+ (apparently people do use that!). He added the comment, "Wait...you mean that turning into an indignant fusspot when the checker at Wal-Mart says 'Happy Holidays' isn't the best way?"
Lutherans such as this teacher and myself don't get so involved in the "War on Christmas" stuff because we believe that Christmas and other big liturgical holy days are mostly celebrated around the altar and pulpit in the church. We don't fight about whether the Baby Jesus will get his due position at the City and County Building next to the other citizens' Festivus Pole, Hanukkah Menorah, Diwali lights, atheist profession of non-belief sign, etc. because we decorate our homes and will be decorating our church after Divine Service this Sunday for Christmas (a season which, for us and other liturgical Christians actually begins on Christmas Day as opposed to ends on that day).
We're currently in Advent, the penitential season of preparation prior to Christmas. So precisely at the time we're not supposed to be partying or too busy for prayer and devotion, the rest of the culture is in a frenzy of merry-making and what not.
My one capitulation to the general culture is that I do say "Merry Christmas" at this time of year and on through Epiphany. I say it in response to people telling me "Happy Holidays" and I say it as I'm checking out at the grocery store to the checker. I say it to people I suspect aren't actually Christian. The only time I don't say "Merry Christmas" is if I know for a fact that the person will take offense. I almost never know that for a fact.
"Happy Holidays" strikes me as all of the potential offensiveness of "Merry Christmas" with none of the specificity (Holidays=Holy Days). "Season's Greetings" kind of makes me want scream. I don't know why. I have never known an actual person (read: someone who isn't employed by a university or media outlet) who celebrated Kwanzaa. There are a dozen Jewish holidays of more significance than Hanukkah. Besides, it's over now.
So Merry Christmas it is.
I'm curious what the Ricochet crowd -- Christian and non-Christian alike -- do. How do you handle greetings?
