Here is one small thing I miss from my Protestant childhood: I never quite reach CSP (Carol Saturation Point) these days. For most of December it's all O Come O Come Emmanuel at church and all Little Drummer Boy in public spaces and in consequence there is just not quite enough Hark the Herald Angels Sing in my world. HtHA = the best best best Christmas carol. And there's no HtHA on the radio once the calendar turns over on December 26.
But! If you volunteer to sing with the choir, you can belt out Christmas carols when it is still Advent because you have to rehearse them. You can belt them out in three-part harmony, even! Those HtHA words are balm to my soul: mild he lays his glory by, ris'n with healing in his wings, veiled in flesh the godhead see. My soul needed some balm this evening.
