The Spanish Catholic Church, or Catholic Church in Spain, is part of the Catholic Church under the spiritual leadership of the Pope in Rome, and the Spanish Episcopal Conference. The Spanish Constitution of 1978 establishes the non-denominationality of the State, providing that the public authorities take into account the religious beliefs of society, maintaining cooperative relations with the Catholic Church and other confessions. Thus, the relations between the Spanish State and The Holy See are regulated by the 1976 agreement and the three 1979 agreements, which modified and replaced the previous 1953 concordat. History According to , Christianity could have been present in Spain from a very early period. St. Paul intend to go to Hispania to preach the gospel there after visiting the Romans along the way. But there is no clear evidence if he ever made it. After 410 AD, Spain was taken over by the Visigoths who had been converted to Arianism around 360. From the 5th to the 7th century, about thirty synods, were held at Toledo to regulate and standardise matters of discipline, decreed uniformity of liturgy throughout the kingdom.

However, there was tension from the Pope and the Catholic Church to oppose Islamic rule in Spain and to "reclaim" Europe. This was the period of the so-called "Golden age of Jewish culture in Spain". The Almohads, who had taken control of the Almoravids' Maghrebi and Andalusian territories by 1147, far surpassed the Almoravids in Islamic fundamentalism, and they notably treated the non-Islamic dhimmis harshly. Faced with the choice of death, conversion, or emigration, many Jews fled to North Africa and Egypt. The Reconquista was the long process by which the Catholics reconquered Spain from Islamic rule by 1492. The Spanish Inquisition was established in 1478 to complete the religious purification of the Iberian Peninsula. In the centuries that followed, Spain saw itself as the bulwark of Catholicism and doctrinal purity. Spanish missionaries carried Catholicism to the Americas and the Philippines, establishing various missions in the newly colonized lands. The missions served as a base for both administering colonies as well as spreading Christianity.
