 Sociologists like Bryan R. Wilson write about some former members of any religious group who may have psychological motivations such as self-justification to criticise their former groups.Wilson states that such individuals are prone to create fictitious "atrocity stories" which have no basis in reality.Many supporters of Opus Dei have expressed the belief that the criticisms of Opus Dei stem from a generalized disapproval of spirituality, Christianity, or Catholicism.
