More than in the case of any other school of theology, it is important to assess liberation theology in its social context. Liberation theology not only asserts a necessary correlation between belief and action; its adherents are also normally active in work with poor communities or one of the many church-linked sectoral support organisations. Liberation theology has also acquired wide influence within the magisterium of the Latin American church: the meeting of the General Conference of Latin American bishops (CEL AM) in Medellin (1968) and Puebla (1979) adopted key concepts, and for the past twenty years a liberationist outlook has shaped the thinking of the Brazilian bishops’ conference, the largest on the continent.The impact of liberation theology in the Latin American church has been profound, though not universal. Where its ideas have been adopted, the church, from being in alliance with the elites and out of touch with the and a new following among the poor, and is treated with a new seriousness by non-Christian radicals. Bishops, who formerly entered the political arena mainly to defend their privileges, now commonly champion the rights of workers, the landless, indigenous peoples and other oppressed groups There has been an explosion of creativity, not only in theology, but in church structure, pastoral practice and liturgy. Liberation theology’s influence has spread beyond Latin America, stimulating similar contextual theologies in other parts of the Third World, and securing recognition of one of its key concepts, the ‘preferential option for the poor’, as an essential element of papal social teaching and a permanent question for Christians in the affluent world.
