A few more hints about the song I've mentioned: written by a self-described agnostic, written to commemorate an anniversary of Abraham Lincoln's birthday.
Unlike the canonical book of Esther, the song does mention God. (But given that the author is agnostic about this God of whom he speaks, what might this tell us about the God who's invoked?)
There's no church.
No Christ. Of course, no gospel. As we might expect, pure law.
It invokes memories of a particular ethnic group.
Later: which song I'm speaking of. And a likely reason why it's in the Lutheran Service Book. And what its inclusion in LSB tells us about the current state and future of the Missouri Synod.
