Liberation theology, is a political movement in Catholic theology which interprets the teachings of Jesus Christ in relation to a liberation from unjust economic, political, or social conditions. It has been described by proponents as "an interpretation of Christian faith through the poor's suffering, their struggle and hope, and a critique of society and the Catholic faith and Christianity through the eyes of the poor", and by detractors as Christianized Marxism.
Liberation theology proposes to fight poverty by addressing its supposed source: sin. In so doing, it explores the relationship betweenChristian theology — especially Roman Catholic theology — and political activism, especially in relation to social 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, S.J., argues that the poor are a privileged channel of God's grace.
Some liberation theologians base their social action upon the Bible scriptures describing the mission of Jesus Christ, as bringing a sword (social unrest), e.g. Isaiah 61:1, Matthew 10:34, Luke 22:35–38 — 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.
