Augustin Arndt was one of the greatest Jesuit writers active in the late nineteenth and early twentieth centuries. His interests included exegesis of the Bible, secular law and canon law. However, his involvement in the sobriety movement is little known. After presenting the outline of the history of the anti-alcohol movement in the Diocese of Wroclaw, the author discusses Arndt’s life and work, focusing on his work as a documentary filmmaker of the sobriety movement in the Diocese of Wrocław. He discusses in turn: the work of Franciszek Bering, Handbook for the clergy and believers developed and translated by Arndt; his own work Brotherhood of abstinence; edited by Arndt the church periodical “Sunday Messenger for the Diocese of Wroclaw” (“Sunday Courier for the Diocese of Wroclaw”), and in particular the addition to it, called “Abstinence.” This supplement was addressed to promoters and members of church sobriety brotherhoods. The author considers A. Arndt as a precursor of the historiography of sobriety movement in the diocese of Wroclaw.
