Conservative Christian colleges, once relatively insulated from the culture war, are increasingly entangled in the same battles over LGBT rights and related social issues that have divided other institutions in America.

Students and faculty at many religious institutions are asked to accept a "faith statement" outlining the school's views on such matters as evangelical doctrine, scriptural interpretation and human sexuality. Those statements often include a rejection of homosexual activity and a definition of marriage as the union of one man and one woman. Changing attitudes on sexual ethics and civil rights, however, are making it difficult for some schools, even conservative ones, to ensure broad compliance with their strict positions.

"Millennials are looking at the issue of gay marriage, and more and more they are saying, 'OK, we know the Bible talks about this, but we just don't see this as an essential of the faith,' " says Brad Harper, a professor of theology and religious history at Multnomah University, an evangelical Christian institution in Portland, Ore.

LGBT students at Christian schools are also increasingly likely to be open about their own sexual orientation or gender identity. Read more and listen to the story via NPR
