This is a season of changes for the Congregation for the Doctrine of the Faith.
First, let me say that I think His Holiness is trying slowly to restore the CDF to its proper importance.
We have seen in recent times the changing of the guard in the Undersecretary’s office.
I have heard from three different places in the last week that when the Pontifical Commission Ecclesia Dei is assumed under the aegis of the CDF, that it will have a new seceretary, perhaps a present official of the CDF. Keep in mind that the Secretary of the PCED, Msgr. Mario Marini died recently. That chair is open.
Some have suggested to me that the new Secretary of the PCED may be Msgr. Guido Pozzo, who is an official of the CDR and a member of the International Theological Commission.
The CDF and PCED will have to take care of the doctrinal discussions with the SSPX.
I think that the liturgy dimension of the PCED will probably be shifted to the CDW. There are good people at the CDW right now, but I still think that, since liturgy is also doctrine, it would also be best treated by the PCED, even with its closer alignment with the CDF.
Just some thoughts.
