The American Protestant mainline tradition has consistently reported losses in membership, participation and institutional support throughout the last three decades. In the midst of this decline, evangelical renewal movements (ERM’s) have arisen from within the denominations expressing a concern over this decline and calling for a return to the teachings and doctrines of the past. Current theory and research would suggest that the ERM’s should soon leave their denominations, perpetuating the well-documented sect to church cycle. But most of these movements show few signs of leaving and many are claiming a broad base of clergy support. This brings us to the questions posed by this research: How are these movements mobilized and sustained? Research on social movements outside the church points to the importance of networks and relational ties in successfully mobilizing movements. Utilizing self-administered, mail questionnaires, this research looks at the impact of clergy ties on the mobilization of religious movements in the Protestant mainline. This research will elucidate the importance of clergy ties in mobilizing movements, when and where critical ties are formed, as well as looking anew at the future of mainline religion.
