The Roman Catholic Church is the largest religious denomination of Christianity with over one billion members. It maintains the claim that it is both organizationally and doctrinally the original Christian Church, founded by Jesus on St. Peter and the other Apostles. The Roman Catholic Church claims an unbroken Apostolic Succession with grace transferred through the laying on of hands. It is both the largest and the oldest continuously operating institution in existence.
Members generally prefer the term Catholic Church, but this term has multiple meanings (see Catholicism); the term Roman Catholic Church is used in this article to avoid confusion. The relationship between the Roman Catholic Church and the Western or Latin and the Eastern Churches within it is dealt with below.
The Second Vatican Council's Decree on the Church Lumen Gentium, 8, declared that "the sole Church of Christ which in the Creed we profess to be one, holy, catholic and apostolic" has a concrete realization (the Latin term is "subsistit") "in the Catholic Church, which is governed by the successor of Peter and by the bishops in communion with him". "Successor of Peter" refers to the Pope.
The Roman Catholic Church has a worldwide membership that worships in every country on Earth. It is a hierarchical organisation in which ordained clergy are divided into the orders of bishops, priests and deacons. The world is divided into 2755 (at the end of 2004) bishoprics (more commonly called a diocese), each with a presiding bishop, responsible for the religious welfare of the believers in his geographical area. The principal bishopric is that of Rome, whose occupant is known as the Pope, considered to be the successor of Saint Peter, the chief of the apostles.
The Church sees itself as set up by Jesus Christ for the salvation of souls. The Church accomplishes this goal through teaching and through administration of sacraments, including baptism, communion, and forgiveness of sins, which grant graces to the believer. Teaching authority is held by the magisterium of the Church, whose teachings are based on both scripture and apostolic tradition. As well as ordained secular clergy, the Church encourages monasticism, and has many orders of monks, friars and nuns who live in celibacy, and devote their lives entirely to God. Other religious practices include fasting, prayer, penance, pilgrimage and meditation.
According to the Catechism of the Catholic Church, the Church's first purpose is "to be the sacrament of the inner union of men with God." Thus the Church's "structure is totally ordered to the holiness of Christ's members." (Catechism of the Catholic Church 775, 773)
The History of the Roman Catholic Church spans nearly two thousand years with the Roman Catholic Church one of the oldest religious institutions in existence. The church claims an unbroken history to the year 33 AD which was the year in which Jesus is said to have been crucified and subsequently risen from the dead, thereafter instructing his followers to establish a new church.
The early Roman Catholic Church played an important role as the state religion of the Roman Empire and would later influence the Holy Roman Empire, as well as serving as the motivating agency for the Crusades. Both the Eastern Orthodox church and the Protestant Reformation can trace origins to the Roman Catholic Church in the Middle Ages.
The Roman Catholic Church has sometimes been involved in questionable activities such as the Spanish Inquisition and pogroms against both Jews and Muslims. Pope John Paul II acknowledged this in the last years of his life, asking publically that God forgive the sins of the early Roman Catholic Church.
Roman Catholic religious orders also have a rich and lengthy history with some Catholic religious orders spanning back to the very earliest days of the church. In the modern age, such institutions confine their time to charity and social work; however, in the past, some Catholic groups were powerful both in the Catholic Church and world politics. The Jesuits, for instance, controlled an economic monopoly on Japan in the 16th century and a bitter rivalry developed with the Franciscans (the novel Shogun is set during this time period). Other examples from history speak of Catholic religious orders almost as secret societies with their own agenda, sometimes separate from that of the Church.
The centre of the Roman Catholic Church's life is the liturgical service of the Eucharist or Mass. On each Sunday and Holy Day of Obligation or on the evening before, Catholics have an obligation to participate in this celebration. For further information, see the article Mass (liturgy) and the references in that article.
Another especially important part of the Church's continual prayer is the Liturgy of the Hours, whose particular characteristic is to consecrate the course of day and night. Lauds and Vespers (morning and evening prayer) are the principal hours. To these are added one or three intermediate prayer periods (traditionally called Terce, Sext and None), another prayer period to end the day (Compline), and a special period at no fixed time devoted chiefly to readings from the Scriptures and ecclesiastical writers. The prayers consist principally of the Psalter or Book of Psalms. Like the Mass, the Liturgy of the Hours has inspired great musical compositions. Earlier names for the Liturgy of the Hours were the Divine Office (a name still used as the title of one English translation), the Book of Hours, and the Breviary.
The Roman Catholic Church recognizes and administers seven sacraments, which are considered gifts of Christ through the Church which give Divine grace to those who receive them. The sacraments are listed here with reference to the section of the Catechism of the Catholic Church (CCC) that deals with each.
The Roman Catholic Church attributes very high authority to 21 Ecumenical Councils: Nicaea I (325), Constantinople I (381), Ephesus (431), Chalcedon (451), Constantinople II (553), Constantinople III (680-681), Nicaea II (787), Constantinople IV (869-870), Lateran I (1123), Lateran II (1139), Lateran III (1179), Lateran IV (1215), Lyons I (1245), Lyons II (1274), Vienne (1311-1312), Constance (1414-1418), Florence (1438-1445), Lateran V (1512-1517), Trent (1545-1563), Vatican I (1869-1870), Vatican II (1962-1965).
Of these, the Orthodox Churches of Byzantine tradition accept only the first seven, the family of "non-Chalcedonian" or "pre-Chalcedonian" Churches only the first three, and the Christians of Nestorian tradition only the first two.
Dialogue has shown that even where the break with one of these ancient Churches occurred as far back as the Councils of Ephesus (431) and Chalcedon (451), long before the break with Constantinople (1054), the few doctrinal differences often concern terminology, not substance.
Emblematic is the "Common Christological Declaration between the Catholic Church and the Assyrian Church of the East"  (note the use in an inter-Church document of "Catholic Church" rather than "Roman Catholic Church"), signed by "His Holiness John Paul II, Bishop of Rome and Pope of the Catholic Church, and His Holiness Mar Dinkha IV, Catholicos-Patriarch of the Assyrian Church of the East", on 11 November 1994. The division between the two Churches in question goes back to the disputes over the legitimacy of the expression "Mother of God" (as well as "Mother of Christ") for the Virgin Mary that came to a head at the Council of Ephesus in 431. The Common Declaration recalls that the Assyrian Church of the East prays the Virgin Mary as "the Mother of Christ our God and Saviour", and the Catholic tradition addresses the Virgin Mary as "the Mother of God" and also as "the Mother of Christ", fuller expressions by which each Church clearly acknowledges both the divinity and the humanity of Mary's son. The co-signers of the Common Declaration could thus state: "We both recognize the legitimacy and rightness of these expressions of the same faith and we both respect the preference of each Church in her liturgical life and piety."
Some, at least, of the most difficult questions in relations with the ancient Eastern Churches concern not so much doctrine as practical matters such as the concrete exercise of the claim to papal primacy and how to ensure that ecclesial union would not mean mere absorption of the smaller Churches by the Latin component of the much larger Roman Catholic Church (the most numerous single religious denomination in the world), and the stifling or abandonment of their own rich theological, liturgical and cultural heritage.
There are much greater differences with the doctrinal views of Protestants, whom Roman Catholics feel have broken continuity with the past, and the true teachings of the apostles, for the sake of what Protestants believe to be the true teaching of the apostles. But even with these groups, dialogue has on both sides clarified some misunderstandings of what the other believes.
The Catechism of the Catholic Church, 85 states that authentic interpretation of the word of God is entrusted to the living Magisterium of the Church, namely the bishops in communion with the successor of Peter.
Main article: Catholic social teaching
The Church holds that the teachings of Jesus call its members to act a particular way in their dealings with the rest of humanity. Among these teachings, as they have been elaborated in recent decades by Catholic thinkers, Bishops' statements and Papal encyclicals, are that every person has a right to life and to a decent minimum standard of living, that humanity's use of God's creation implies a responsibility to protect the environment, and that the range of circumstances under which military force is permissible is extremely limited.
Particular Churches within the single Roman Catholic Church
Unlike "families" or "communions" of Churches that see themselves as distinct Churches, the Church of those who are in full communion with the Pope considers itself a single Church, not a federation of Churches. It has authoritatively expressed this self-understanding in, for instance, the 28 May 1992 Letter to the Bishops of the Catholic Church on some aspects of the Church understood as communion, 9.
Accordingly, it has never adopted the usage of those who apply the term "Roman Catholic" to the Latin or Western Church alone, to the exclusion of the Eastern Churches that also are in full communion with the Bishop of Rome. When it employs the term "Roman Catholic Church", which it rarely does except in its relations with other Churches, it means the whole Church "governed by the successor of Peter and by the bishops in communion with him", wherever they live and whether they are of Eastern or Western tradition, since this Church has Rome as its centre. The only other meaning it would give to "Roman Catholic" is "a Catholic who lives in Rome", as a Catholic who lives in Warsaw could be called a Warsaw Catholic.
On the other hand, the Roman Catholic Church attaches great importance to the particular Churches within it, whose theological significance the Second Vatican Council highlighted. Two categories of particular Churches are distinguished.
Particular Churches or Rites
The higher level of particular Churches is that of what the Second Vatican Council’s Decree on the Catholic Eastern Churches Orientalium Ecclesiarum, 2 calls "particular Churches or rites". The long-established use of the term "rite" for these particular Churches is due to the central place that the Eucharist holds in the Roman Catholic Church, making each particular Church's liturgy its most noted distinguishing mark.
However, the word "rite" is used not only of particular Churches but also of liturgical rites. Examples are the Ambrosian rite, the Mozarabic rite and the Roman rite, different liturgical rites used within the one Latin particular Church or Latin rite (singular). And terms such as "Byzantine rite" may refer to a liturgical rite used by more than one particular Church. To avoid the ambiguity to be found in the terms "particular Church" and "rite", the 1983 Code of Canon Law adopted instead the term "autonomous ritual Church" (in Latin, "Ecclesia ritualis sui iuris") for the same reality; and the 1990 Code of Canons of the Eastern Churches shortened this to "autonomous Church" (in Latin, "Ecclesia sui iuris").
The autonomy of each such Church, Eastern or Western, shows in its distinctive liturgy, canon law, theological tradition etc. The Latin or Western particular Church is governed by the Code of Canon Law, while the Code of Canons of the Eastern Churches outlines the discipline that the Eastern particular Churches have in common.
The official yearly Vatican directory, Annuario Pontificio (Libreria Editrice Vaticana), gives the following list of rites (in the sense of particular Churches) within the Roman Catholic Church:
A. Eastern rites of Alexandrian tradition: Coptic, Ethiopic (2).
B. Eastern rites of Antiochian tradition: Malankara, Maronite, Syrian (3).
C. Eastern rite of Armenian tradition: Armenian Church (1).
D. Eastern rites of Chaldaean or East-Syrian tradition: Chaldean, Malabar (2).
E. Eastern rites of Constantinopolitan or Byzantine tradition: Albanian, Belarussian, Bulgarian, Greek, Greek-Melkite, Hungarian, Italo-Albanian, Romanian, Russian, Ruthenian, Slovak, Ukrainian (12).
F. Latin rite (1).
Particular or Local Churches
In Catholic teaching, each diocese too is a local or particular Church: "A diocese is a section of the People of God entrusted to a bishop to be guided by him with the assistance of his clergy so that, loyal to its pastor and formed by him into one community in the Holy Spirit through the Gospel and the Eucharist, it constitutes one particular church in which the one, holy, catholic and apostolic Church of Christ is truly present and active" (Second Vatican Council, Decree on the Pastoral Office of Bishops in the Church Christus Dominus, 11).
The particular Churches within the Roman Catholic Church, whether rites or dioceses, are seen as not simply branches or sections of a larger body. Theologically, each is considered to be the embodiment in a particular place of the whole Roman Catholic Church. "It is in these and formed out of them that the one and unique Catholic Church exists" (Second Vatican Council, Dogmatic Decree on the Church Lumen Gentium, 23.).
What most obviously distinguishes the Roman Catholic Church from others is the link between its members and the Pope. The Catechism of the Catholic Church, 882, quoting the Second Vatican Council’s document Lumen Gentium, states: "The Pope, Bishop of Rome and Peter’s successor, ‘is the perpetual and visible source and foundation of the unity both of the bishops and of the whole company of the faithful.’"
In certain circumstances, this papal primacy, which is referred to also as the Pope's Petrine authority or function, involves papal infallibility, i.e. the definitive character of the teaching on matters of faith and morals that he propounds solemnly as visible head of the Church. In any normal circumstances, exercise of this authority will involve previous consultation of all Catholic bishops.
The Catechism of the Catholic Church, 891 says: "’The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful – who confirms his brethren in the faith – he proclaims by a definitive act a doctrine pertaining to faith or morals... The infallibility promised to the Church is also present in the body of bishops when, together with Peter’s successor, they exercise the supreme Magisterium,’ above all in an Ecumenical Council."
The Pope lives in Vatican City, set up in 1929 as a minute, but symbolically important, independent state within the city of Rome. The body of officials that assist him in governance of the Church as a whole is known as the Roman curia. The term "Holy See" (i.e. of Rome) is generally used only of Pope and curia, because the Code of Canon Law, which concerns governance of the Latin Church as a whole and not internal affairs of the see (diocese) of Rome itself, necessarily uses the term in this technical sense.
The present rules governing the election of a pope are found in the apostolic constitution Universi Dominici Gregis. This deals with the powers, from the death of a pope to the announcement of his successor’s election, of the cardinals and the departments of the Roman curia; with the funeral arrangements for the dead pope; and with the place, time and manner of voting of the meeting of the cardinal electors, a meeting known as a conclave. This word is derived from Latin com- (together) and clavis (key) and refers to the locking away of the participants from outside influences, a measure that was introduced first as a means instead of forcing them to reach a decision.
A pope is given the option to resign. (The term "abdicate" is not usually used of popes.) There have been several cases, though the two best known are those of Pope Celestine V in 1294 (who, though the poet Dante pictured him condemned to hell for this action, was canonized in 1313) and Pope Gregory XII, who resigned in 1415 to help end the Great Western Schism.
Cardinals are appointed by the pope, generally from the ranks of his assistants in the curia and bishops of important sees, Latin or Eastern, throughout the world.
In 1059, the right of electing the Pope was assigned exclusively to the principal clergy of Rome and the bishops of the seven "suburbican" sees. Because of their resulting importance, the term "cardinal" (from Latin "cardo", meaning "hinge") was applied to them. In the twelfth century the practice of appointing ecclesiastics from outside Rome as cardinals began. Each cardinal is still assigned a church in Rome as his "titular church" or is linked with one of the suburbicarian dioceses. Of these sees, the Dean of the College of Cardinals holds that of Ostia while keeping his preceding link with one of the other six sees. Traditionally, there have thus been only six cardinals who hold the rank of Cardinal Bishop, but when Eastern rite patriarchs are made cardinals, they too hold the rank of Cardinal Bishop, without being assigned a suburbicarian see, still less a church in Rome. The other cardinals have the rank either of Cardinal Priest or Cardinal Deacon.
Only a limited number (which has been set at a maximum of 120) can be admitted to a conclave. The rule has therefore been made that cardinals who have celebrated their eightieth birthday before the pope’s death may not join the conclave. Accordingly, no more than 120 ecclesiastics below the age of eighty may normally be made cardinals, but there may be any number over that age. This has enabled the Pope to confer the cardinalatial dignity on particularly worthy older clergy, such as theologians, or priests who have suffered long imprisonment under dictatorial regimes.
The colour associated with the robes of cardinals is a crimson red, while the red of bishops who are not cardinals (and of Honorary Prelates and Apostolic Prothonotaries) is really a Roman purple, and that of the lower class of monsignors (known as Chaplains of His Holiness) has a violet hue.
The hat and tassels of cardinals’ armorial bearings are red; those of bishops and lesser prelates are green.
Bishops are the successors of the apostles in the governance of the Church. The Pope himself is a bishop and traditionally uses the title "Venerable Brother" when writing formally to another bishop. The typical role of a bishop is to provide pastoral governance for a diocese. Bishops who fulfill this function are known as diocesan ordinaries, because they have what canon law calls ordinary (i.e. not delegated) authority for a diocese. Other bishops may be appointed to assist them (auxiliary and coadjutor bishops) or to carry out a function in a broader field of service to the Church. Even when a bishop retires from his active service, he remains a bishop, since the ontological effect of the sacrament of holy orders is permanent.
On the other hand, titles such as archbishop or patriarch imply no ontological alteration, but are generally associated with special authority. Some of the Eastern Catholic Churches are headed by a patriarch. (A few bishops in the Latin Church also have the title of patriarch, but in their case the title is merely honorary.) Two Eastern Churches are headed by a major archbishop, a bishop who has practically all the powers of a patriarch, but without the title. Smaller Eastern Churches (consisting however of at least two dioceses or, to use the Eastern term, two eparchies) are headed by a metropolitan. Within the Latin Church too, dioceses are normally grouped together as ecclesiastical provinces, in which the bishop of a particular see has the title of metropolitan archbishop, with some very limited authority for the other dioceses, which are known as suffragan sees. However, almost all the authority of a metropolitan archbishop to intervene in case of necessity with regard to a suffragan see belongs, in the case of the metropolitan see itself, to the senior suffragan bishop. (In some Eastern Churches, the term "metropolitan bishop" corresponds instead to "diocesan ordinary" in the Latin Church; and an Anglican usage of "suffragan" corresponds to Catholic "auxiliary bishop.") The Latin-Church title of primate is now merely honorary.
Bishops of a country or region form an episcopal conference and meet periodically to discuss common problems. Decisions in certain fields, notably liturgy, fall within the exclusive competence of these conferences. But the decisions are binding on the individual bishops only if agreed to by at least two-thirds of the membership and confirmed by the Holy See.
Bishops are assisted by priests and deacons. Parishes, whether territorial or person-based, within a diocese are normally in the charge of a priest, known as the parish priest or the pastor. Dioceses too, though normally territorial, may be person-based (as, for instance, a military ordinariate).
The honorary title of Monsignor is conferred on some priests. It corresponds to a knighthood or similar honour for a lay person.
In the Latin Church only celibate men, as a rule, are ordained as priests, while the Eastern Catholic Churches also ordain married men. Both sides maintain the tradition of holding it impossible for a priest to marry. Even a married priest whose wife dies may not then marry.
To explain this tradition, one theory holds that, in early practice, married men who became priests – they were often older men, "elders" – were expected to refrain permanently from sexual relations with their wives, perhaps because they, as priests representing Christ, were treated as the Church's spouse. When at a later stage it was clear that not all did refrain, the Western reaction was to ordain only celibates, while the Eastern Churches relaxed the rule, so that Eastern Orthodox Churches now require their married clergy to abstain from sexual relations only for a limited period before celebrating the Eucharist. The Church in Persia, which in the fifth century became separated from the Church described as Orthodox or Catholic, decided at the end of that century to abolish the rule of continence and allow priests to marry, but recognized that it was abrogating an ancient tradition. The Coptic and Ethiopic Churches, whose separation came slightly later, allow deacons (who are ordained when they are boys) to marry, but not priests. The theory in question, if true, helps explain why all the ancient Christian Churches of both East and West, with the one exception mentioned, exclude marriage after priestly ordination, and why all reserve the episcopate (seen as a fuller form of priesthood than the presbyterate) for the celibate.
Since the Second Vatican Council, the Latin Church admits married men of mature age to ordination as deacons, but not if they intend to advance to priestly ordination. Ordination even to the diaconate is an impediment to a later marriage.
The Roman Catholic Church and the other ancient Christian Churches see priestly ordination as a sacrament effecting an ontological change, not as the deputizing of someone to perform a function or as the admission of someone to a profession such as that of medicine or law. They also consider that priestly ordination can be conferred only on males. In the face of continued questioning, Pope John Paul II felt obliged to confirm the existing teaching that the Church is not empowered to change this practice: "In order that all doubt may be removed regarding a matter of great importance, a matter which pertains to the Church's divine constitution itself, in virtue of my ministry of confirming the brethren (cf. Luke 22:32) I declare that the Church has no authority whatsoever to confer priestly ordination on women and that this judgment is to be definitively held by all the Church's faithful."  The Roman Catholic Church thus holds this teaching as irrevocable and as having the character of infallibility, not in virtue of the apostolic letter Ordinatio Sacerdotalis itself, from which this quotation is taken, but because the teaching "has been preserved by the constant and universal Tradition of the Church and firmly taught by the Magisterium ."
What in the Latin Church were called minor orders have, since the Second Vatican Council, been reduced to two, lectors and acolytes. These are now called "instituted ministries", and those on whom they are conferred are no longer classified as members of the clergy.
Public Consecrated Life
Within the Catholic Church, there are those who publicly undertake to observe as obligations what the Christian gospel proposes as counsels rather than commands. Some Catholics, in particular hermits and consecrated virgins, do so individually. Others group together to form what are called religious institutes. The term "religious order", which in its strict sense refers only to a subset of these institutes, is commonly used also of all of them.
There is a great variety of religious institutes. Some have only lay members, others have both priests and lay members, others still may have only priests and men preparing for priesthood. Some date from the earliest centuries of Christianity, others spring up every year.
These groups normally begin as an association formed, with the consent of the diocesan bishop, for the purpose of becoming a religious institute. After time has provided proof of the rectitude, seriousness and durability of the group, the bishop, after consulting the Holy See, may formally set it up as a religious institute, for which he is responsible. Later, when it has grown in numbers, perhaps extending also into other dioceses, and further proved its worth, then the Holy See may grant it formal approval, bringing it under the Holy See's responsibility, rather than that of the bishops of the dioceses where it is present. For the good of the institute and to provide for the needs of their apostolate, the Holy See can exempt them from the governance of the local bishops, bringing them entirely under the authority of the Holy See itself or of someone else.
The oldest existing forms of such institutes are those of monks and nuns, such as the Benedictines of the West and the Basilians of the East, living in monasteries. Around the thirteenth century Mendicant Orders, such as of those of the Dominicans and Franciscans, arose. Unlike the monks and nuns, the members of these orders had their convents not in the country but in the towns, which were becoming increasingly important. One of the best known of those that appeared still later is the Society of Jesus, which today is the religious institute with the largest number of members (known as Jesuits).
Typically, members of religious institutes take vows of poverty, chastity and obedience. For some, the vow of stability in a monastery or to live according to a particular written rule is considered to include these vows. Other institutes add further vows. People wishing to join a religious institute may spend some time as postulants, then as novices, and then one or more periods with temporary vows, before committing themselves fully with perpetual vows.
Unless they are priests, male members of religious institutes are usually referred to as "Brother", while in female institutes most members are called "Sister", but the superior of the whole institute, or even of a single community, is usually called "Mother" or "Mother Superior".
Secular institutes are another form of consecrated life. They differ from religious institutes in that their members live their lives in the ordinary conditions of the world, either alone, in their families or in fraternal groups.
Somewhat similar are the societies of apostolic life, dedicated to pursuit of an apostolic purpose, such as educational or missionary work. They do not take religious vows, but live in common, striving for perfection through observing the "constitutions" of the society to which they belong.
The total number of Catholics in the world is over one billion. They are found in nearly every country, though they are more concentrated in the Americas and Europe. They currently make up 63% of the population of North and South America, 40% of Europe, roughly 20% of Sub-Saharan Africa, and 3% of Asia .
In Europe, Catholic majorities are found in Austria, Belgium, Croatia, France, Hungary, Ireland, Italy, Lithuania, Malta, Poland, Portugal, Slovakia, Slovenia and Spain. Germany, the Netherlands, and Switzerland, as well as the Northern Ireland, are about equally divided between Catholics and Protestants. In the Czech Republic, Roman Catholics make up 39% of the population. Catholics are a significant minority in Britain, where their faith underwent a revival in the 19th and early 20th Century after three centuries of relentless persecution.
Nearly all Latin American countries have large Catholic majorities, among them being such heavyweights as Brazil, Mexico, Colombia, and Argentina. The United States of America has a large minority of Catholics; this is a legacy of massive immigration, mainly from countries like Italy, Ireland and Germany. The number of Catholics grew from virtually nothing in 1790 to about a quarter of the total population by 1920, a proportion that remains today. A majority of Canadians are also Catholic, given the strong historical presence of France in the region and the vast number of people that have immigrated from Catholic countries.
Catholicism has spread relatively recently to some parts of the world; there are now some 115 million in Africa. Other countries where significant populations have developed are South Korea and East Timor. But, aside from an older presence in Uganda, the Catholicism in those countries tends to be somewhat more eclectic than in more established regions of the world. Catholics form a majority in the Philippines, which was once a Spanish colony.
The number of Catholics in the world continues to increase, through population growth in developing countries and, to a lesser extent, spread to new areas. The increase between 1978 and 2000 was 288 million. Protestant evangelicals have succeeded in making inroads into parts of Latin America, but remain a small percentage of the population. In most industrialized countries, church attendance has decreased since the 19th Century, similarly to other faiths.
Throughout the centuries of its existence, the Roman Catholic Church has met with criticism for various reasons. The particular controversies are discussed in separate articles.
Historically, the Church's response to heresy and witchcraft through the Inquisition and its association with witchhunts are subjects of criticism. The Church is also accused of being hostile to democracy, freedom of religion, and freedom of speech, and of supporting absolute monarchy and, later, Fascism and Falangism. The Church came under fire from the philosophers of the Age of Enlightenment, who perceived the Church's doctrines as superstitious and hindering the progress of civilization. Other thinkers and academics criticised it for being anti-science for clinging to Ptolemaic geocentrism and for the famous trial of Galileo Galilei.
Contemporary criticism concerns the Church's stance on issues such as artificial birth control, homosexuality, abortion and embryonic stem cell research, and in particular the Church's resulting opposition to the use of condoms to prevent the spread of AIDS. Actions by bishops or other officials have aroused controversy, with some praising them for upholding Catholic teaching on faith and morals, and others condemning what they see as heavy-handed attempts to limit a right of conscience, as when it was stated that the Eucharist should not be given to politicians who oppose legislation limiting access to abortion or support broadening access. Another issue given wide coverage has been the Roman Catholic Church sex abuse scandal that broke towards the end of the twentieth century.
