As concerns Sunday among the Moravians in Salem

"We think it would be well to abide by the recommendations of the Helfer Conferenz 

concerning playing on Sunday. In connection with the subject of Sunday we desire to say that in business nothing ought to be sold on Sunday, nor charged, neither should work be taken in or given out. Neither should the musicians play Minuets, Polonaises, Marches, or other worldly music, but rather confine themselves to Chorales."  -- December 1, 1772
