While I certainly support most of the views above, especially Joe, Musket and Bobert, I'd be happy if the pope was less of a centralist: dealing with the things Stim raised are all about addressing the issue in front of you as it is, not referring to a centrally managed set of rules and decrees. So the central rules should be few and general - "abuses of clerical power, in whatever guise, are not tolerated and are always investigated, using independant civil agents wherever possible", for example.
