The fact that the CDF is not making a lot of noise, not attracting a lot of attention to itself, does not mean that it's not doing anything.  Perhaps it is functioning less like a decision-making entity and more like an advisory/consultative body, supporting individual bishops and conferences of bishops.  It would be good if the CDF understood itself as a ministry of service to the bishops, not as a check on them or as superior to them; it would be even better if Pope Francis has communicated that understanding to them; and it would be better yet if the pope would codify that understanding.  For too long, the CDF (and its predecessor, the 'Holy Office of the Inquisition') usurped authority that rightly belongs to the bishops.
