Lutherans believe that worship is an act of receiving God’s gifts. That’s why the worship service we use is called the Divine Service. It’s a time during which God comes to us through His Word and Sacraments. Lutheran Service Book includes five different versions, or settings, of the Divine Service. There is only one Divine Service, but there are different settings. Some of the music and language differ between the settings, but the core of them all is the same—God delivering to us His forgiveness and salvation.
There are a lot of ideas about what makes music appropriate for church. This post is an excerpt from Ceremony and Celebration and provides a few principles as defined by Paul H. D. Lang.
