What’s ultimately exciting about sexuality is mystery. The mysteriousness of the sexual union is found in the sense that this union transcends everyday life. That’s why today’s sexual revolutionaries want to define their very identities in terms of their sexual desires and practices. They are off the mark on that, but not totally. Sexual union gets at the core not only of who we are but also of the universe itself. The apostolic Christian faith tells us why.

Why does the Creator pronounce it “not good” that Adam should be alone (Gen 2:18)? Why is it that Elohim gives to the primeval man a woman formed from his own flesh and bone, for whom he is to leave everything to become “one flesh” (Gen 2:22-24)? Why is it that rebellion against the Creator always manifests itself in rebellion against the order of human sexuality (Gen 6:1-2; Rom 1:24)?

The Apostle Paul tells us precisely why: because human sexuality points to a grander cosmic mystery that has now been revealed in these last days of human history.
