Ein feste Burg ist unser Gott
In general, the characters find themselves in situations that have to be overcome by placing their faith in God. While the show is explicitly faith-based, there is no content specifically about the Lutheran Church, which made broadcasters more comfortable with the idea of an overtly religious mainstream children's show. The only reference to Lutherans in the show was the theme song, an instrumental version of "A Mighty Fortress Is Our God", and the Luther rose displayed in the opening theme and end credits.
