He published under the pen name Stefan Martha in "Dziś i Jutro", the PAX Association magazine (1950–1953). These periodicals represented a different styles of Catholicism. Pax sought to 'collaborate' with the communist government, while "Tygodnik Powszechny" took a more oppositional stance (it was legal but its circulation was limited). Herbert definitely finished his cooperation with PAX in 1953. "Przegląd Powszechny" was closed and "Tygodnik Powszechny" was transferred to PAX after it refused to publish an obituary of Joseph Stalin's death. In this situation Herbert decided that his cooperation with PAX was impossible.
