Some of these include the Apostolic See, the Pontifical See, and the Roman See. These terms are used to refer to the spiritual authority of the Pope and the administrative apparatus of the Catholic Church. The Holy See represents the highest-level governing body of the Catholic Church, and is responsible for important decisions regarding faith and policy. Regardless of the term used, the Holy See is an essential institution for millions of Catholics around the world.
