Christian theology is a theology of liberation. It is a rational study of the being of God in the world in light of the existential situation of an oppressed community, relating the forces of liberation to the essence of the gospel, which is Jesus Christ. This means its sole reason for existence is to put into ordered speech the meaning of God’s activity in the world, so that the community of the oppressed will recognize that its inner thrust for liberation is not only consistent with the gospel but is the gospel of Jesus Christ. There can be no Christian theology that is not identified unreservedly with those who are humiliate and abused. In fact, theology ceases to be a theology of the gospel when it fails to arise out of the community of the oppressed. For it is impossible to speak of the God of Israelite history, who is the God revealed in Jesus Christ, without recognizing that God is the God of and for those who labor and are overladen.
