How indigenous was the Evangelical Free Church movement in Tsarist Russia? Was it simply a foreign import? To what extent did it threaten the political stability of the nation and encroach upon the existing Russian and German churches? On the Edge examines the efforts of the regimes to suppress the movement and how the movement not only survived but also expanded. To what extent did the movement bring upon itself unnecessary opposition because of aggressiveness and tactics? Albert Wardin describes the contributions the movement made to the religious life of Russia and examines its numerical success.
