From time to time I quibble with Lutherans over the law / Gospel paradigm and the third use of the law. You see, if you're Reformed, according to some Lutherans, you're clueless about such issues, and all you're interested in is law, law, law. Because you're Reformed, you don't even understand the gospel: you've missed the gospel in the sacraments, you worship predestination as the gospel, and you love the fact that Christ is sending people to Hell and didn't die for them. The Reformed are so clueless they probably read "Sinners in the Hands of Angry God" to their children as a bedtime story. In fact, some Lutherans have gone so far as to emphatically suggest the Reformed view of things is far more dangerous than Roman Catholicism.
Anyway, now that that three second rant is finished, Lutheran minister Rev. McCain has an interesting post called, Aversion to Sanctification: A Phobic Reaction. Worth a look.
