This book presents the canonical institutions - principally potestas regiminis and ecclesiastical offices - which are the backbone of the entire governance structures within the Catholic Church, from the Roman Pontiff to the parish priest. It offers a canonical treatment of the material which at the same time refers to the underlying theological principles. It is, as well a reflexion on the pastoral form of exercising governance for the good of souls.
