In the present lecture, Father Jaki first examines the conciliar tradition fro Trent to the present with a view to comparing developments in magisterial statements to contemporaneous developments in science, particularly in cosmology. He notes in this connection the curious absence of reference in modern theological discourse to the universe which scientist explore. He then provides considerations of the place of the universe in ancient creedal statements of the Church and in the attitudes of scientists and philosophers in the modern period. Finally, he proposes to modern theology a number of issues which need to be addressed if the Church is to engage contemporary scientific cosmology n a fruitful manner.
