To read the papers or watch the news, one would think that sex and gender are the only issues facing Christians today. Christian thought about war and injustice, or about how to believe in God in this postmodern age, almost never makes the headlines. And the discussion about sex and gender focuses on particular aspects of those issues. Can gay people be ordained? Can a woman be a presiding bishop? Should wives obey their husbands? Such questions seem to arrive in popular debate without much context of Christian thought about sexuality in general, about how we make moral decisions or about what it means to be human. In particular, liberal Christians seem to have no systematic response to the conservative conviction that once we modify traditional sexual mores we begin a slide toward total sexual degradation.
