Studies of interest groups typically sample from organizations or lobbyists registered with a government – those already engaged in political action. Because of this design choice, the questions asked of organizational systems are constrained. We take a different tack, pursuing investigation of one organizational form, ministerial organizations (MOs), in a wide variety of systems to ask about whether and how they engage in public affairs across ecologies. Specifically, we ask: What pressures affect whether MOs engage a public versus private purpose? How do MOs forage in public affairs, with what size and diversity of coalition? The data result from a hyper-network survey of MO contacts, identified by a national sample of United Methodist Church clergy. We find, contrary to assertions in previous work that religious interest groups respond to ecological pressures in a similar manner as other interest groups.
