Does the Church need to be “reformed”?

“There is constant talk about Pope Francis being a “reformer” and it is assumed without anyone challenging the idea, that the Vatican  (and by extension the whole Catholic Church) is desperately in need of being reformed. But what does this call for “reform” really mean? Everybody has their own idea, but I get the feeling that the generally agreed and assumed definition is the agenda for change that the secular media simply assume must be the right thing to do.”
