A "Nuncio" is a diplomatic representative of the Vatican City to a foreign country. Officially known as an Apostolic Nuncio, this role involves promoting the interests of the Catholic Church and maintaining relations between the Church and the government of the host nation. Nuncios often hold the rank of an ambassador and are involved in various diplomatic activities. In addition to their diplomatic duties, Nuncios also play a significant role in the appointment of bishops within their assigned countries. They serve as a liaison between the Pope and local church authorities, ensuring that the Church's mission is effectively carried out in different regions around the world.
