The Underground Pewster nails everything that is wrong with "dialogue" about sexuality: a hypothetical conversation between Bishop Waldo and a simple pewsitter.
I particularly loathe the phrase "living in relationship", which sits between "dialogue" and "living in community" on my Shelf of Theological Vacuity. Every two people live in some sort of relationship; the important thing is pinning down what that relationship needs to be like, and you know, God/people (your choice) invented these things called "rules" and "laws" to help us through this. "That kind of relationship" is discussed at length in scripture, and besides it doesn't take a lot of observation to realize that (a) long-term monogamy is what works best, and (b) "relationship" is a word which means "letting your sexual appetites and the drudgery of everyday life dictate your behavior."
At any rate, it took about thirty seconds for "not that kind of relationship" to become the new catchphrase in the Wingate household.
