Yet, there is nothing wrong with the concept of a Curia - a group of offices in the Vatican that serve the pope in the work of governing the Church.  The problem is, and has been, that through a series of events, the Curia took on powers that rival, if not taken from, that of the pope.  The Fathers of Vatican II made the necessary changes (they thought) to reverse this situation in favor of the bishops WITH Peter.  Originally, the Curia was intended to serve the pope and the bishops of the Church.  Vatican II worked to return the Curia to that position.  Pope St. John Paul II worked against it to re-centralize power in the Vatican.  Now, we are in the process of once again pulling the Church away from the grips of the Curia.  This is, thankfully, +Francis' mission as Reformer.  Those who don't like it are the same ones who reject the Council.  We take it as being so with a grain of salt.
