Benefict is doing so with the most egregious of our problems (American seminaries, Franciscans of Assisi, open homosexuals in priesthood, to mention a few of the biggies).
He also squarely dealt with the IMMORALITY of relative morality. He stood four-square behind tradtional Christian, Scriptural moral absolutes and moral imperatives. Not an easy thing to do today in the worship and courtship of cultural and religious diversity -- that is, accepting other absolutes/imperatives as equal and/or superior to our own.
He is also dealing with so many other issues. One biggie, in my mind, in the union of Orthodoxies with Rome. All but the Russians have joined. I think that was huge. The sticking point with many Russians was the Polishness of John Paul II.
Rome and Lutherans also signed a momentous agreement at the 500th anniverary of Luther's protests.
These weren't all officially Benedict, but I bet he was in on them in some form. They were all papal interdictions/interventions.
My two cents.
