Well, the years of JPII as Pope and Ratzinger as Prefect of the CDF saw the ideas of dialogue and discussion smashed to pieces.  Got no better when Ratzinger became BXVI and Levada became Prefect.  They believe in their own power as God given and that is how they act.  

There is an enormous ego the Holy Spirit must tame in bringing truth into the world.  I think we often get more ego than truth, or as much ego as truth, anyway.  Still, some truth does slip through.  There is good intention, I am sure.  But you know what people say about roads paved with good intentions.  

I do not know how Pope Francis views the role of the CDF in his own pontificate, but, since he doesn't seem to like sledgehammers very much, I don't think Francis will use it the same way past popes did.  He will work around them.  More, Francis is intent on extending the power of bishops conferences which may reduce the power of offices like the CDF.

I think we need to pray for a long pontificate for Pope Francis.
