Last year my husband wrapped up a composing project in which he set Luther's Small Catechism to music (I think most of my readers know this, but perhaps a few do not). The songs--66 of them--were first included piecemeal in Concordia Publishing House's Growing in Christ Sunday School curriculum, but now they have been compiled available independently in CD and songbook formats. It is my understanding that both have been selling well. (We wouldn't know firsthand as my husband was paid for his work on a stipend basis so receives no royalties from sales.)
But the fact that something is purchased does not mean that it is used. (Just ask any homeschooling mom.) So my husband loves hearing from real life people that they are utilizing the fruits of his labor and that these songs are actually doing what they were written to do: helping children learn the catechism.
Over the last few years he has heard from a number of people who have told him just that. These stories are worth more to him than you can possibly know. I heard a few more of them at the Concordia Catechetical Academy Symposium this week. What a joy it was for me to hear how parents and their children have been blessed by my husband's work, especially after having had a front row seat to see the many hours of inspiration, craft, and sweat that went into it. He has given much to his parish and to the church at large over the years, but I am beginning to think that this may be his most lasting contribution.
Here's a recent blog post from a Lutheran pastor (of one of our sister synods) on how he has used this resource both in his parish and his home.
