Abstract: This article addresses the religious career of a transgender mystic who died as Père Jean in 1967. While it might sound contradictory, for scholars working on women, mysticism and charisma, sources on Jean’s life offer exceptional insights. When Jean made the news in the 1920s, he headlined as Bertha Mrazek/Georges Marasco and was still perceived as a woman. Bertha’s cross-dressing, miraculous cure and law suit started discussions about what it meant to be a charismatic woman in post-war Belgium. Rather than focusing on the sensational aspects, the emphasis here is on Jean’s reinventions, the historicity of his appeal to others, and the importance of ideals of gender and sanctity as well as the historical context in the reception of this transgender mystic.
