Concordat

A concordat is a convention between the Holy See and a sovereign state that defines the relationship between the Catholic Church and the state in matters that concern both, i.e. the recognition and privileges of the Catholic Church in a particular country and with secular matters that impact on church interests. According to P. W. Brown the use of the term "concordat" does not appear "until the pontificate of Pope Martin V (1413–1431) in a work by Nicholas de Cusa, entitled De Concordantia Catholica". The first concordat dates from 1098, and from then to the beginning of the First World War the Holy See signed 74 concordats. Due to the substantial remapping of Europe that took place after the war, new concordats with legal successor states were necessary. The post-World War I era saw the greatest proliferation of concordats in history. Although for a time after the Second Vatican Council, which ended in 1965, the term 'concordat' was dropped, it reappeared with the Polish Concordat of 1993 and the Portuguese Concordat of 2004. A different mode of relations between the Vatican and various states is still evolving, often contentiously, in the wake of a growing secularism and religious pluralism in the western world. The Catholic church historically claimed not to be bound to one form of government over another, but was willing to work with any kind of government, so long as the rights of God and believers were maintained. Pius XI wrote in 1933: Universally known is the fact that the Catholic Church is never bound to one form of government more than to another, provided the Divine rights of God and of Christian consciences are safe. She does not find any difficulty in adapting herself to various civil institutions, be they monarchic or republican, aristocratic or democratic. From a church–state perspective, the contentions regarding concordats involves two perspectives. From a Catholic perspective, the Church has the moral and theological right to enter into diplomatic relations with states in order to reach agreements regarding the care of its members residing there.
