242. Dialogue between science and faith also belongs to the work of evangelization at the service of peace. Whereas positivism and scientism “refuse to admit the validity of forms of knowledge other than those of the positive sciences”, the Church proposes another path, which calls for a synthesis between the responsible use of methods proper to the empirical sciences and other areas of knowledge such as philosophy, theology, as well as faith itself, which elevates us to the mystery transcending nature and human intelligence. Faith is not fearful of reason; on the contrary, it seeks and trusts reason, since “the light of reason and the light of faith both come from God” and cannot contradict each other. Evangelization is attentive to scientific advances and wishes to shed on them the light of faith and the natural law so that they will remain respectful of the centrality and supreme value of the human person at every stage of life. All of society can be enriched thanks to this dialogue, which opens up new horizons for thought and expands the possibilities of reason. This too is a path of harmony and peace.
