In our more passionate moments, we imagine romantic love to be akin to Christian love, an uncritical, expansive emotion that declares I will love you for everything that you are, a love that has no conditions, that draws no boundaries, that adores every last shoe, that is the embodiment of acceptance. But the arguments that hound lovers are a reminder that Christian love is not prone to survive a move into the bedroom. Its message seems more suited to the universal than the particular, to the love of all men for all women, to the love of two neighbors who will not hear each other snoring.
