While I would agree that a meaningful dialogue is not possible on the basis of mere reaffirmation of church teaching and what purports to be natural law, I would also point out that an uncritical acceptance of the whole spectrum of contemporary sexual practice would be equally meaningless. Our society has crossed many lines that need to be reexamined by people of faith, and I would hope that includes some non-celibates who treat sexuality as more than a concept. I'm getting tired of well-meaning priests and nuns telling us what we should think about sex and do with pur bodies.
