Can. 360 The Supreme Pontiff usually conducts the business of the universal Church by means of the Roman Curia, which fulfills its duty in his name and by his authority
for the good and the service of the churches; it consists of the Secretariat of State or the Papal Secretariat, the Council for the Public Affairs of the Church, congregations, tribunals and other
institutions, whose structure and competency are defined in special law.
Can. 361 In this Code the term Apostolic See or Holy See applies not only to the Roman Pontiff but also to the Secretariat of State, the Council for the Public Affairs of
the Church and other institutions of the Roman
Curia, unless the nature of the matter or the context of the words makes the contrary evident.
