I was sitting in the Blessed Virgin's chapel, praying my rosary before Mass yesterday, the first Sunday after Christmas, Feast of the Holy Family, when I heard a jovial usher respond to another man's Merry Christmas greeting with; "That's all over now - Christmas is over - now it's the New Year!" (He repeated his catechesis to everyone who came in.) I recognized the man's voice and was really surprised he was so convinced Christmas was over already - he is a daily Mass goer after all. Sunday was only the second day of Christmas.
I would never attempt to correct the gentleman, especially since he was so convinced Christmas was over. One can explain things to religious people over and over, but one is usually unsuccessful in changing their opinion. I couldn't help being entertained by the irony of it all however. Throughout Advent we heard the militant demands that secular businesses and newsrooms say "Merry Christmas", while Catholics were told to hold back on the Christmas celebrations until Christmas... and predictably, the day after Christmas, not a few people think it's over. (My sister takes her tree down the day after. I know!)
To be sure marketing and retail proclaim it is over, and since many consumers worship in that temple, I suppose their Christmas is over. However, if one prays, and especially if one's prayer is based in liturgical prayer, one understands that Christmas is a season traditionally referred to as Christmastide, and the first eight to twelve days are Christmas. (Albeit with Epiphany transferred to Sunday, the liturgical season appears shortened this year as well.)
Anyway, religious people who like to wear their religion on buttons and bumper stickers ought to know better.
