Offering a compelling understanding of Christian faith in the age of scientific reason, this book is part of the commitment of the Vatican Observatory to the interdisciplinary research on faith and science and to the evangelization of scientific culture. It is addressed to professors of university courses in science and theology, to students interested in these topics, and to everyone who wants to reflect on a Christian theology developed within our contemporary scientific context. The author writes to advance scientific perspectives in fundamental theology, taking into account the relevant questions that the sciences pose to Christian faith.
