Opus Dei is an issue but it's not the only 'cult within a cult' in the Catholic Church, not even the first. They just happen to be the most recent fashion. Popes have always had to balance the power and influence of this or that organization - franciscans, dominicans, benedictines, any one of these (and more) had to be contained at some point.
