Our Advent observations are pretty simple. Neither my husband nor I grew up with Advent observations in the home. Heck, my husband didn't even have much by way of Christmas celebrations growing up. For the first two decades of our marriage, we wandered around broad evangelicalism, which looks askance at anything liturgical, except for Christmas and Easter (and some Calvinists don't even recognize Christmas). For nearly the past decade we have been at home~ very much at home~ in confessional Lutheranism and have grown in our appreciation and love for the liturgy. Every year, I think, we do a little better job observing Advent.
