I happened upon a book by a former student of mine, Matthew Rueger, now a pastor in Iowa with a Ph.D. The book, just out from CPH, is Sexual Morality in a Christless World. Matt (if I can still call him that) tells about being put in the position of defending Christian morality in an Iowa State college classroom, whose professor was teaching pretty much the opposite. He became a regular guest lecturer, up against great opposition, but his input grew to be respected, if not appreciated. Those experiences became the basis of this book.
The Rev. Dr. Rueger includes a fascinating treatment of sexual morality in the Greco-Roman world. The wide practice of homosexuality in that classical culture–specifically, pederasty, the sexual use of young boys–is particularly illuminating. He also treats sexual morality in the ancient Hebrew world, which was not without problems of its own (such as easy divorce). The Christian perspective on sexual morality, he shows, has always been counter-cultural. It took its shape from consideration of our identity in Christ.
