Fe religiosa y ciencias naturales. Pasado y presente.

The article presents the relationship between religious faith and natural sciences within a historical perspective. Three great periods are distinguished: classical, enjoying a substantial harmony between science and belief in God; modern period, characterized by a radical rationalism that can be seen as the root of the structural conflict between science and religion; contemporary phase, with the collapse of rationalism, notwithstanding the great prestige of natural science, often perceived within a secularist framework. It is argued that no objective reasons oppose today scientific knowledge to theology and religion. The present state of natural sciences is favourable for a new complementarity between secular/rational views and theological/religious faith.
