Latin American liberation theology (, ) is a synthesis of Christian theology and Marxian socio-economic analyses, that emphasizes "social concern for the poor and political liberation for oppressed peoples".Dictionary of Historical Terms (1998), 2nd ed., Chris Cook, ed., p. 203. Beginning in the 1960s after the Second Vatican Council and influenced by Camilism, which can be considered the predecessor of it, liberation theology became the political praxis of Latin American theologians such as Gustavo Gutiérrez, Leonardo Boff, and Jesuits Juan Luis Segundo and Jon Sobrino, who popularized the phrase "preferential option for the poor". It arose principally as a moral reaction to the poverty and social injustice in the region, which Cepal deemed the most unequal in the world.

This expression was used first by Jesuit Fr. General Pedro Arrupe in 1968 and soon after this the World Synod of Catholic Bishops in 1971 chose as its theme "Justice in the World". It was popularized in 1971 by the Peruvian priest Gustavo Gutiérrez, who wrote one of the movement's defining books, A Theology of Liberation. Other noted exponents include Leonardo Boff of Brazil, and Jesuits Jon Sobrino of El Salvador and Juan Luis Segundo of Uruguay.Richard P. McBrien, Catholicism (Harper Collins, 1994), chapter IV.Gustavo Gutierrez, A Theology of Liberation, 1st (Spanish) ed. Lima, Peru, 1971; 1st English ed. Orbis Books (Maryknoll, New York), 1973.

The Latin American context also produced Protestant advocates of liberation theology, such as Rubem Alves, José Míguez Bonino, and C. René Padilla, who in the 1970s called for integral mission, emphasizing evangelism and social responsibility.

History A major player in the formation of liberation theology was the Latin American Episcopal Conference (CELAM). Created in 1955 in Rio de Janeiro, Brazil, CELAM pushed the Second Vatican Council (1962–1965) toward a more socially oriented stance.Robert Pelton, "Latin America, Catholicism in" in R. P. McBrien, ed., The HarperCollins Encyclopedia of Catholicism, HarperCollins, 1995.

After the Second Vatican Council, CELAM held two conferences which were important in determining the future of liberation theology: the first was held in Medellín, Colombia, in 1968, and the second in Puebla, Mexico, in January 1979. The Medellín conference debated how to apply the teachings of Vatican II to Latin America, and its conclusions were strongly influenced by liberation theology, which grew out of these officially recognized ideas. While the Medellín document is not a liberation theology document, it laid the groundwork for much of it, and after it was published, liberation theology developed rapidly in the Latin American Catholic Church.Elisabeth Erin Williams.

Peruvian priest Gustavo Gutiérrez has been widely regarded as the "father of liberation theology", with his 1971 book A Theology of Liberation considered to have been instrumental in the movement's formation.

Cardinal Alfonso López Trujillo was a central figure after the Medellín Conference. As a priest in Bogotá in 1968, he did not attend the conference. But he was elected in 1972 as general secretary of CELAM, and then its president in 1979 (at the Puebla conference). He represented a more conservative position, becoming a favourite of Pope John Paul II and the "principal scourge of liberation theology". (Available upon request) López's faction became predominant in CELAM after the 1972 Sucre conference, and in the Roman Curia after the 1979 CELAM conference in Puebla.

Despite the conservative bishops' predominance in CELAM, liberation theology remained popular in South America. Thus at the 1979 Puebla Conference the conservative bishops were met by strong opposition from those in the clergy who supported the concept of a "preferential option for the poor" and basic ecclesial communities, approved at the Medellín conference.

Pope John Paul II gave the opening speech at the Puebla Conference in 1979. The general tone of his remarks was conciliatory. He criticized radical liberation theology, saying, "this idea of Christ as a political figure, a revolutionary, as the subversive of Nazareth, does not tally with the Church's catechesis"; however, he did acknowledge that "the growing wealth of a few parallels the growing poverty of the masses", and he affirmed both the principle of private property and that the Church "must preach, educate individuals and collectivities, form public opinion, and offer orientations to the leaders of the peoples" towards the goal of a "more just and equitable distribution of goods".

Some liberation theologians, however, including Gustavo Gutiérrez, had been barred from attending the Puebla Conference. Working from a seminary and with aid from sympathetic, liberal bishops, they partially obstructed other clergy's efforts to ensure that the Puebla Conference documents satisfied conservative concerns. Within four hours of the Pope's speech, Gutiérrez and the other priests wrote a 20-page response, which was circulated at the conference, and has been claimed to have influenced its outcome. According to a socio-political study of liberation theology in Latin America, a quarter of the final Puebla documents were written by theologians who were not invited to the conference.Smith, Christian. The Emergence of Liberation Theology

Theology Liberation theology could be interpreted as an attempt to return to the gospel of the early church where Christianity is politically and culturally decentralized.Populorum progressio [On the Development of Peoples], Encyclical Letter of His Holiness Pope Paul VI promulgated on March 26, 1967

Liberation theology proposes to fight poverty by addressing its alleged source, the sin of greed. In so doing, it explores the relationship between Christian theology (especially Roman Catholic) and political activism, especially in relation to economic justice, poverty, and human rights. The principal methodological innovation is seeing theology from the perspective of the poor and the oppressed. For example, Jon Sobrino argues that the poor are a privileged channel of God's grace.

Some liberation theologians base their social action upon the Biblical description of the mission of Jesus Christ as bringing a sword (social unrest), e.g., , , – and not as bringing peace (social order). This Biblical interpretation is a call to action against poverty, and the sin engendering it, to effect Jesus Christ's mission of justice in this world.

Gustavo Gutiérrez gave the movement its name with his 1971 book, A Theology of Liberation. In this book, Gutiérrez combined populist ideas with the social teachings of the Catholic Church. He was influenced by an existing socialist current in the Church which included organizations such as the Catholic Worker Movement and the , a Belgian Christian youth worker organization. He was also influenced by Paul Gauthier's Christ, the church and the poor (1965). Gutiérrez's book is based on an understanding of history in which the human being is seen as assuming conscious responsibility for human destiny, and yet Christ the Saviour liberates the human race from sin, which is the root of all disruption of friendship and of all injustice and oppression.Gustavo Gutierrez, A Theology of Liberation (London: SCM Press, 1974), 36f Gutiérrez also popularized the phrase "preferential option for the poor", which became a slogan of liberation theology and later appeared in addresses of the Pope. Drawing from the biblical motif on the poor, Gutiérrez asserts that God is revealed as having a preference for those people who are "insignificant", "marginalized", "unimportant", "needy", "despised", and "defenseless". Moreover, he makes clear that terminology of "the poor" in the Christian Bible has social and economic connotations that etymologically go back to the Greek word .Gutierrez, Gustavo. The God of Life. Maryknoll, New York: Orbis, 1991. (Original: El Dios de la vida. Lima: CEP, 1989.) p. 112 To be sure, as to not misinterpret Gutiérrez's definition of the term "preferential option", he stresses, "Preference implies the universality of God's love, which excludes no one. It is only within the framework of this universality that we can understand the preference, that is, 'what comes first'."Nickoloff, James B., ed. Gustavo Gutierrez: Essential Writings. Maryknoll, New York: Orbis, 1996, p. 145

Gutiérrez emphasized practice (or, more technically, "praxis") over doctrine. He clarified his position by advocating a circular relationship between orthodoxy and orthopraxis, in a symbiotic relationship.Gutierrez, Gustavo. The Truth Shall Make You Free: Confrontations. Maryknoll, New York: Orbis, 1990. (Original: La verdad los hara libres: confrontaciones. Lima: CEP, 1986) His reading of prophets condemning oppression and injustice against the poor (i.e., Jeremiah 22:13–17) informs his assertion that to know God (orthodoxy) is to do justice (orthopraxis).Gutierrez, Gustavo. The Power of Poor in History. Maryknoll, New York: Orbis, 1983. (Original: La fuerza historica de los obres: selección de trabajos. Lima: CEP, 1971.) Cardinal Joseph Ratzinger (later Pope Benedict XVI), however, criticized liberation theology for elevating orthopraxis to the level of orthodoxy. Richard McBrien summarizes this concept as follows:

Another important hallmark for Gutiérrez's brand of liberation theology is an interpretation of revelation as "history". For example, Gutiérrez wrote:

Gutiérrez also considered the Church to be the "sacrament of history", an outward and visible sign of an inward and spiritual grace, thus pointing to the doctrine of universal salvation as the true means to eternal life, and assigning the Church itself to a somewhat temporal role, namely, liberation.

Practice One of the most radical and influential aspects of liberation theology was the social organization, or reorganization, of church practice through the model of Christian base communities, also called basic ecclesial communities. Liberation theology strove to be a bottom-up movement in practice, with Biblical interpretation and liturgical practice designed by lay practitioners themselves, rather than by the Church hierarchy. In this context, sacred text interpretation is understood as "praxis".

The priest Camilo Torres (a leader of the Colombian guerrilla group ELN) celebrated the Eucharist only among those engaged in armed struggle against the army of the Colombian state. He also fought for the ELN.

Liberation theology seeks to interpret the actions of the Catholic Church and the teachings of Jesus Christ from the perspective of the poor and disadvantaged. In Latin America, liberation theologians specifically target the severe disparities between rich and poor in the existing social and economic orders within the state's political and corporate structures. It is a strong critique of the economic and social structures, such as an oppressive government supported by a conservative Church hierarchy and by First World economic interests, that allow some to be extremely rich while others are unable even to have safe drinking water.
