The Pew Research Center ranked Spain as the 16th out of 34 European countries in levels of religiosity, with 21% of the population declaring they were "highly religious" in the poll.
[6] Although a majority of Spaniards self-identify as Catholics, younger generations tend to ignore the Church's moral doctrines on issues such as pre-marital sex, homosexuality, same-sex marriage or contraception.
[18] [Asked only to Catholics or believers in another religion] How often do you attend Mass or other religious services, except for those related to ceremonies of social nature, such as weddings, communions or funerals?
(March 2022 CIS survey)[19] While Catholicism is still the largest religion in Spain, most Spaniards—and especially the younger—choose not to follow the Catholic teachings in morals, politics or sexuality, and do not attend Mass regularly.
[34] In the last decades religious practice has fallen dramatically and atheism and agnosticism have grown in popularity, with over 14 million people (30.3% of the population as of January 2020[update])[35] having no religion.
World-famous examples include the Holy Week in Seville, the Romería de El Rocío in Huelva or the Mystery Play of Elche, while the Sanfermines in Pamplona and the Falles of Valencia have mostly lost their original religious nature.
The destination of most is Santiago's baroque cathedral, where believers can visit what is said to be the tomb of James, the apostle, who, according to Catholic tradition, brought Christianity to Spain and Portugal.
[39][40] Most if not all cities and towns celebrate a patron saint's festival, no matter how small or known, which often includes processions, Mass and the like but whose actual religious following is variable and sometimes merely nominal.
[42] In religion à la carte, people mix popular Roman Catholic beliefs and traditions with their own worldview and/or esoteric, self-help, New Age or philosophical borrowings they like, resulting in a unique personal 'soft' spirituality without any possible church sanction or endorsement.
[45] Possibly Bishop John Stowe of Lexington, Kentucky (USA), put it best to justify the quest and search among many Catholics, especially in the area of sexuality and spirituality: "...Catholicism cannot be reduced to a morality clause.
Spanish Heathen groups include the Odinist Community of Spain–Ásatrú, which identifies as both Odinist and Ásatrú, the Asatru Lore Vanatru Assembly, the Gotland Forn Sed and Circulo Asatrú Tradición Hispánica, of which four, the first one is officially registered by the State; Celtist or Druidic groups include the Dun Ailline Druid Brotherhood (Hermandad Druida Dun Ailline) and the Fintan Druidic Order, both registered.
The Counter-Reformation (1563–1648) was especially strong in Spain and the Inquisition was not definitively abolished until 1834, thus continuing their animosity towards Islam, Judaism, Protestantism and parts of the Enlightenment for most of its history.
[96][7][8][22][23] The 1978 Constitution abolished Catholicism as the official religion of the state, while recognizing "the religious beliefs of all Spaniards" and establishing "appropriate cooperation" with the Catholic Church and other confessions.
There is some archaeological evidence of Christianity slowly penetrating the Peninsula from Rome and Roman Mauretania via major cities and ports, especially Tarragona, since the early 2nd century.
[citation needed] Theodosius I issued decrees that effectively made Nicene Christianity the official state church of the Roman Empire.
In 711 an Arab raiding party led by Tariq ibn-Ziyad crossed the Strait of Gibraltar, then defeated the Visigothic king Roderic at the Battle of Guadalete.
During this period the number of Muslims increased greatly through the migration of Arabs and Berbers, and the conversion of local Christians to Islam (known as Muladis or Muwalladun) with the latter forming the majority of the Islamic-ruled area by the end of the 10th century.
[102] In the ensuing Spanish Civil War, alleged communists and anarchists in Republican areas killed about 7,000 priests, the majority murdered between July and December 1936.
[103][104][105] On the other hand, the small Protestant minority was harshly persecuted by the "national" side, most churches were closed and many priests and religious figures were jailed or killed.
Franco secured in return the right to name Roman Catholic bishops in Spain, as well as veto power over appointments of clergy down to the parish priest level.
In the late 1960s, the Vatican attempted to reform the Church in Spain by appointing interim, or acting, bishops, thereby circumventing Franco's stranglehold on the country's clergy.
The article further states, however, that: "The public authorities shall take the religious beliefs of Spanish society into account and shall maintain the consequent relations of cooperation with the Catholic Church and the other confessions."
The government would continue, however, its program of subsidizing Catholic schools, which in 1987 cost the Spanish taxpayers about US$300 million exclusive of the salaries of teachers, which were paid directly by the Ministry of Education and Science.
In a significant change from the pre-Civil War era, the church had accepted the need for the separation of religion and the state, and it had even discouraged the creation of a Christian Democratic party in the country.
Another sign of the church's declining role in Spanish life was the diminishing importance of the controversial secular religious institute Opus Dei (Work of God).
Despite its public commitment to a nonpolitical stance, Opus Dei members rose to occupy key positions in the Franco régime, especially in the field of economic policy-making in the late 1950s and the early 1960s.
After the 1973 assassination of Prime Minister Luis Carrero Blanco (often rumored to be an Opus Dei member), however, the influence of the institute declined sharply.
Since 2003, the involvement of the Catholic Church in political affairs, through special groups such as Opus Dei, the Neocatechumenal Way or the Legion of Christ, especially personated through important politicians in the right-wing People's Party, has increased again.
This implication has had, as a consequence, a renewed criticism from important sectors of the population (especially the majority of left-wing voters) against the Church and the way in which it is economically sustained by the State.
[63] Despite the arrival of large numbers of Catholic, Orthodox, Muslim and Protestant immigrants, irreligion continues to be the fastest growing demographic as of 2018[update].
