Benedict XVI: Lecture at the University of Regensburg
This gives rise to two principles which are crucial for the issue we have raised. First, only the kind of certainty resulting from the interplay of mathematical and empirical elements can be considered scientific. Anything that would claim to be science must be measured against this criterion. Hence the human sciences, such as history, psychology, sociology and philosophy, attempt to conform themselves to this canon of scientificity. A second point, which is important for our reflections, is that by its very nature this method excludes the question of God, making it appear an unscientific or pre-scientific question. Consequently, we are faced with a reduction of the radius of science and reason, one which needs to be questioned.
I will return to this problem later. In the meantime, it must be observed that from this standpoint any attempt to maintain theology’s claim to be “scientific” would end up reducing Christianity to a mere fragment of its former self. But we must say more: if science as a whole is this and this alone, then it is man himself who ends up being reduced, for the specifically human questions about our origin and destiny, the questions raised by religion and ethics, then have no place within the purview of collective reason as defined by “science”, so understood, and must thus be relegated to the realm of the subjective. The subject then decides, on the basis of his experiences, what he considers tenable in matters of religion, and the subjective “conscience” becomes the sole arbiter of what is ethical. In this way, though, ethics and religion lose their power to create a community and become a completely personal matter. This is a dangerous state of affairs for humanity, as we see from the disturbing pathologies of religion and reason which necessarily erupt when reason is so reduced that questions of religion and ethics no longer concern it. Attempts to construct an ethic from the rules of evolution or from psychology and sociology, end up being simply inadequate.
Before I draw the conclusions to which all this has been leading, I must briefly refer to the third stage of dehellenization, which is now in progress. In the light of our experience with cultural pluralism, it is often said nowadays that the synthesis with Hellenism achieved in the early Church was an initial inculturation which ought not to be binding on other cultures. The latter are said to have the right to return to the simple message of the New Testament prior to that inculturation, in order to inculturate it anew in their own particular milieux. This thesis is not simply false, but it is coarse and lacking in precision. The New Testament was written in Greek and bears the imprint of the Greek spirit, which had already come to maturity as the Old Testament developed. True, there are elements in the evolution of the early Church which do not have to be integrated into all cultures. Nonetheless, the fundamental decisions made about the relationship between faith and the use of human reason are part of the faith itself; they are developments consonant with the nature of faith itself.
