It's lieder, an art song, not sacred, so technically it's not supposed to be used. I wish people would consider the Faure. Much more beautiful setting.
I would have no problem with any of the three we’ve been discussing. I can’t see why you make the distinction, other than Schubert’s denomination (I’m guessing Lutheran). Deprive yourselves all you want. We won’t. We happily use Gregorian chant, Roman hymns, etc, and think them easily as beautiful and reverent as anything our home team composed.
Charity, it’s not just for money anymore.
