Samuel Stefan Osusky was a leading intellectual in Slovak Lutheranism and a bishop in his church. In 1937 he delivered a prescient lecture to the assembled clergy, "The Philosophy of Fascism, Bolshevism and Hitlerism", that clearly foretold the dark days ahead. As wartime bishop, he co-authored a "Pastoral Letter on the Jewish Question", which publicly decried the deportation of Jews to Poland in 1942; in 1944 he was imprisoned by the Gestapo for giving moral support to the Slovak National Uprising against the fascist puppet regime.

Paul R. Hinlicky traces the intellectual journey with ethical idealism's faith in the progressive theology of history that ended in dismay and disillusionment at the revolutionary pretensions of Marxism-Leninism. Hinlicky shows Osusky's dramatic rediscovery of the apocalyptic "the mother of Christian theology", and his input into the discussion of the dialectic of faith and reason after rationalism and fundamentalism.
