It's been a while since "permissiveness" was blamed for America's social ills. Wall Street thievery and wildcate ventures including Bernie Madoff's helped set aside the notion that the old nemesis could be invoked on liberals with impunity -- and permissiveness talk sort of went away.
Now the pope's letter to the Irish, and the premise behind Rome's investigation of nuns, signal a revival. In one case, Benedict says child abuse was in large measure egged on when the "renewal" called for by Vatican II "was sometimes misinterpreted," a situation made more confusing by "profound social change" in and around it.
Nothing Benedict says indicates he thinks anything is wrong with church laws and discipline. Things just got lax and the church sheriffs were distracted from enforcing those laws. The remedy is to do a better job. There's no need to reform the system itself.
Unmentioned is the permissivness angle. Bishops are told they "failed, at times, greviously, to apply the long established norms of canon law to the crime of child abuse." But so far the bishops face no sanctions for this permissive behavior.
