This article analyzes, through an essentially qualitative approach, the shift in denominations of Ivorian religious leaders in the Pentecostal milieu in Île-de-France, moving from official designations to «professional» designations. The study is based on observations and semi-structured interviews with religious leaders. The results highlight different dynamics. First, the new designations respond to a marketing challenge. Second, the role of pastor has become more than just a status, it has become a central function in the Pentecostal community of Ivorian immigrants in Île-de-France. Finally, the different denominations observed among immigration candidates are related to a process of identity construction.
