Paul McCain has a good blog on Bo Giertz's book ,,The Hammer of God" (in the original Swedish, ,,Stengrunden" which means ,,the stone ground" or ,,the rock foundation") and a concise summary of the book.
Lutheran Visuals offers a 50-minute DVD on chapter one of Giertz's book. The DVD was filmed in Sweden, and thus is in Swedish, but there are English subtitles. This DVD (entitled ,,The Hammer of God") is faithfully and powerfully captures part one of Giertz's book. The scene with Savonius, Katrina, and Johannes is wonderfully done and well-acted. Click here for a 12-minute preview of the movie from Lutheran Visuals.
Henric Schartau (1757-1825) features prominently in chapter six of Giertz's book, when a young pastor preaches one of Schartau's sermons on Transfiguration Sunday. Here is the entire translation of Schartau's sermon.
