A personal ordinariate is a canonical structure within the Catholic Church enabling former Anglicans to maintain some degree of corporate identity and autonomy with regard to the bishops of the geographical dioceses of the Catholic Church and to preserve elements of their distinctive Anglican spiritual and liturgical patrimony. Its precise nature is described in the apostolic constitution Anglicanorum Coetibus of 4 November 2009 and in the complementary norms of the same date.
