The world does not set the agenda for the church. Only Christ, the head of the church, establishes its ministry through the Word. The task of the church is to exalt its head, to teach only the doctrines he has revealed, to worship him as he has commanded, and to order its life by what he has ordained. The church is not an agent of social transformation, though it may contribute to it. The purpose of the church is not to save the world, but to save God’s people from the world. These two models have vied with each other throughout the history of American Protestantism. Their differences lay at the heart of the New School-Old School division in nineteenth-century Presbyterianism and the modernist-fundamentalist controversy of the twentieth century.
