This book comes as something of a shock from the great theologian, Karl Barth. Somehow we'd expect him to lead a great pacifist movement but no -- he calls us to a Holy War, a war against National Socialism which he is convinced is opposing Christ. It is a call to arms against National Socialism in particular and in general a call to the Church to support those who take up arms against the Anti-Christ. Barthian theology has become a school. His followers and all thinking people will do well to study this little book for the author knows National Socialism, he knows its leaders, its policies, and he knows the people who have had to exist under Hitler's regime. As this book was originally published in Switzerland in German, we hope it reached the German Church ahead of the Nazi censors.
