Foreign relations of the Holy See treaties. Traditionally, an agreement on religious matters between the Holy See of the Catholic Church and a sovereign state is called a concordat. This often includes both recognition and privileges for the Catholic Church in a particular country, such as exemptions from certain legal matters and processes, issues such as taxation, as well as the right of a state to influence the selection of bishops within its territory. Foreign relations of the Holy See The Holy See has long been recognised as a subject of international law and as an active participant in international relations. One observer has said that
Legal status of the Holy See personality akin to that of states, has led professor Ian Brownlie to define it as a ""sui generis" entity". Moreover, the Holy See itself, while claiming international legal personality, does not claim to be a State. Cardinal Jean-Louis Tauran, former Secretary for Relations with States of the Secretariat of State of the Holy See, has underlined that we must avoid the temptation of assimilating the Holy See and its international action with that of a State, with their thirst for power. For him, the Holy See is unquestionably a sovereign subject of international law but of a predominantly religious nature.
