Pietisten
During Rosenius' editorship, the magazine was essentially written by him, and was his main literary channel. In this way it had a great influence. His articles have subsequently been published as reflections and writings with a total circulation of two million, and another million in other languages, despite the fact that they are not particularly reader-friendly. Rosenius and Waldenström contributed to the founding of Evangeliska Fosterlandsstiftelsen (EFS, the Swedish Evangelical Mission, 1856) and the Svenska Missionsförbundet (SMF, Swedish Missions Society, 1878), the former being a revivalist movement within the Church of Sweden, the latter a free church. This  contradiction led the EFS, in reaction to the founding of the SMF, to reissue the first fifteen volumes under the title "Pietisten". , which Rosenius had edited, while "Pietisten" under Waldenström became the official mouthpiece of the SMF in 1909 and was merged with the magazine "Missionsförbundet" in 1919.
