The RCC does not believe it is beholden to any secular entity. It is above them, a divine institution.  It knows best how to handle things. Its been running things its own way for centuries.   Butt out!  Its magnificent handling of clerical sexual abuse is exhibit one.  It has resisted the UN on child protection because it is "the father" who knows best.  Why don't pesty secular busybodies evaporate? It has more important things to do like building cathedrals, rewording liturgical texts, re-designing episcopal garb, managing museums, etc.  We don't have time to piddle with twaddle.
