Author Torbjørn Greipsland has written or edited 18 books on topics ranging from emigration to Christian artists to the Norwegian royal family. For his latest, To the Ends of the Earth (Ventura, 2017), he set out to document what he considered an underappreciated aspect of his country’s history: Norway’s contributions to missionary work around the globe.

In doing so, he came to realize just how in sync Norwegian American missionaries were with the ELCA—even those who served well over a century ago. “As the ELCA does today, so did the pioneers,” Greipsland said. Both aspired to build schools, provide health care and bolster indigenous Christians in leadership.
