The Christian contribution is essential to the fight for economic and cultural freedom in Latin America. Out of the struggle for a just society comes a rethinking of the Christian faith: the theology of liberation that is revivifying Christianity all over the world. Practical Theology of Liberation is a fundamental text for all those passing from the European political theology of the 1960s to the faith of the future. It comes from a world where that faith is forged in a constant encounter with the forces of evil. Hugo Assmann is a Brazilian priest. He shows that it is essentially analysis of history, for knowledge that events come first distinguishes Christianity from philosophical systems. Theologians of liberation have to analyze the actual situation, reflect theologically, and act pastorally. That means joining forces with the politically committed.
