These two theodicies manifest in socioeconomic stratification within religiously similar groups. For example, U.S. American "mainline" Protestant churches with upper class congregations generally "promote order, stability, and conservatism, and in so doing proved to be a powerful source of legitimation of the status quo and of existing disparities in the distribution of wealth and power," because much of the wealth of the church comes from the congregation.[11] In contrast, Pentecostal churches find their roots in among working class persons with a theodicy of misfortune. Instead of supporting status quo, these churches may advocate "change intended to advance the cause of justice and fairness".[11] The theodicies of these churches, which are enmeshed in their origins, practices, and preaching, thus reinforce segregation by social class.
