Taking into account that the authentic magisterium of the Bishops, namely what they teach insofar as they are invested with the authority of Christ, must always be in communion with the Head of the College and its members,(83) when the doctrinal declarations of Episcopal Conferences are approved unanimously, they may certainly be issued in the name of the Conferences themselves, and the faithful are obliged to adhere with a sense of religious respect to that authentic magisterium of their own Bishops. However, if this unanimity is lacking, a majority alone of the Bishops of a Conference cannot issue a declaration as authentic teaching of the Conference to which all the faithful of the territory would have to adhere, unless it obtains the recognitio of the Apostolic See, which will not give it if the majority requesting it is not substantial. The intervention of the Apostolic See is analogous to that required by the law in order for the Episcopal Conference to issue general decrees.(84) The recognitio of the Holy See serves furthermore to guarantee that, in dealing with new questions posed by the accelerated social and cultural changes characteristic of present times, the doctrinal response will favour communion and not harm it, and will rather prepare an eventual intervention of the universal magisterium.
23. The very nature of the teaching office of Bishops requires that, when they exercise it jointly through the Episcopal Conference, this be done in the plenary assembly. **Smaller bodies —the permanent council, a commission or other offices—do not have the authority to carry out acts of authentic magisterium either in their own name or in the name of the Conference, and not even as a task assigned to them by the Conference**.
