教皇庁, or the Holy See, is the central governing body of the カトリック教会. It is led by the 教皇, who is the spiritual leader of Catholics worldwide. The Holy See operates from バチカン市国, an independent city-state surrounded by Rome, Italy. The Holy See is responsible for the administration of the Church, including diplomatic relations with other countries. It also oversees various religious, educational, and charitable activities globally, promoting the teachings of キリスト教 and engaging in interfaith dialogue.
