There are also autonomous Eastern Catholic Churches consisting of a single province and headed by a metropolitan. Metropolitans of this kind are to obtain the pallium from the Pope as a sign of his metropolitan authority and of his Church's full communion with the Pope, and only after his investment with it can he convoke the Council of Hierarchs and ordain the bishops of his autonomous Church. In his autonomous Church it is for him to ordain and enthrone bishops and his name is to be mentioned immediately after that of the Pope in the liturgy.
