On May 21, 2005, President George W. Bush delivered the commencement address at Calvin College in Grand Rapids, Michigan. As candidate and as president, George W. Bush had developed a reputation for paying close attention to the concerns of the conservative evangelical Protestants who cement his political base. Few institutions of higher learning seemed to fit the "conservative Christian" profile better than Calvin. The president's visit should have been a meeting of the minds, but Mr. Bush's visit to Calvin was hardly smooth. One-third of the Calvin faculty endorsed a letter protesting the president's policies--especially in Iraq--and also his relative indifference to the plight of the poor. These protests at Calvin exemplify how conservative religious higher institutions have moved away from fundamentalist pieties. In this article, the author examines the mainstreaming of conservative religious higher institutions and the problems they face in the process. One of the main problems being faced by these institutions is diversity. They want students from many racial backgrounds to attend so they learn to speak in the language of diversity, but they also want to preserve their particular religious identity so they also speak in the language of uniformity. Because evangelical Christianity is itself so multiracial, colleges that speak in its name ought to be more diverse than secular ones. But because they lack sufficient appreciation for diversity in all its aspects--religious and intellectual, as well as racial and ethnic--they fall behind secular institutions in their ability to bring together students from a wide variety of backgrounds.
