As Christians have challenged the cultural ethos of the Sexual Revolution, in the popular consciousness Christianity has often become associated with a fixation upon and a negative attitude towards sex. Framed only by their opposition to our prevailing sexual culture, orthodox Christian sexual ethics can seem judgmental and even pathological. Why Christians should care so much about sex in the first place is quite unclear to many. However, as we frame the Christian challenge to the Sexual Revolution by the Christian faith’s own positive account of sex, the reasons for the opposition will become more apparent and our challenge to our culture will be more robust.
