For many years the theology of liberation, which emerged from Latin America in the 1970s, was viewed with suspicion and even hostility in Rome. In this historic exchange, Father Gustavo Gutiérrez, one of the original architects of liberation theology, and Cardinal Gerhard Müller, current Prefect of the Congregation for the Doctrine of the Faith, offer a new and positive chapter. Cardinal Müller, who as a student of Gutiérrez spent many summers working in Peru, writes with deep feeling and conviction about the contributions of liberation theology to church teaching--particularly in its articulation of the preferential option for the poor. In his own contribution here, Gutiérrez lays out the essential ideas of liberation theology, its ecclesial location, and its fresh enunciation of the gospel for our time.
