From Sect to Church: A Sociological Interpretation of the Baha'i Movement 

<br/><br/> -  - 
<br/><br/> Berger is one of the foremost mid-twentieth century sociologists.  His was the first sociological analysis of the Baha'i religion.  Berger sought to describe two fundamental transformations of the Baha'i Faith: (1) the transformation from a millenarian movement within Shii Islam into an independent religion with a worldwide following ; (2) the 'routinization of charismatic leadership' into largely rational-legal forms.  He uses the concept of 'motif' to study fundamental concerns of the religion and defines two major Baha'i motifs: the gnostic and the millenarian.
