Pope Francis has reorganized the internal structure of the Vatican’s doctrine office into two sections — the latest step in his ongoing reform of the Roman Curia.

In a letter issued motu proprio (of his own accord) on Feb. 14, Pope Francis centralised the tasks of the Congregation for the Doctrine of the Faith into a doctrinal section and a disciplinary section.

The department previously had a third section, which dealt with marriage cases. With the motu proprio, titled Fidem servare, the responsibilities of the marriage office will be moved under the doctrinal section.
