26 The events of 1989 took place principally in the countries of Eastern and Central Europe. However, they have worldwide importance because they have positive and negative consequences which concern the whole human family. These consequences are not mechanistic or fatalistic in character, but rather are opportunities for human freedom to cooperate with the merciful plan of God who acts within history. The first consequence was an encounter in some countries between the Church and the workers' movement, which came about as a result of an ethical and explicitly Christian reaction against a widespread situation of injustice. For about a century the workers' movement had fallen in part under the dominance of Marxism, in the conviction that the working class, in order to struggle effectively against oppression, had to appropriate its economic and materialistic theories. In the crisis of Marxism, the natural dictates of the consciences of workers have re-emerged in a demand for justice and a recognition of the dignity of work, in conformity with the social doctrine of the Church. The worker movement is part of a more general movement among workers and other people of good will for the liberation of the human person and for the affirmation of human rights. It is a movement which today has spread to many countries, and which, far from opposing the Catholic Church, looks to her with interest. The crisis of Marxism does not rid the world of the situations of injustice and oppression which Marxism itself exploited and on which it fed. To those who are searching today for a new and authentic theory and praxis of liberation, the Church offers not only her social doctrine and, in general, her teaching about the human person redeemed in Christ, but also her concrete commitment and material assistance in the struggle against marginalization and suffering. In the recent past, the sincere desire to be on the side of the oppressed and not to be cut off from the course of history has led many believers to seek in various ways an impossible compromise between Marxism and Christianity. Moving beyond all that was short-lived in these attempts, present circumstances are leading to a reaffirmation of the positive value of an authentic theology of integral human liberation. Considered from this point of view, the events of 1989 are proving to be important also for the countries of the Third World, which are searching for their own path to development, just as they were important for the countries of Central and Eastern Europe.
