... The university was also very proud of its two theological faculties. It was clear that, by inquiring about the reasonableness of faith, they too carried out a work which is necessarily part of the "whole" of the universitas scientiarum, even if not everyone could share the faith which theologians seek to correlate with reason as a whole. This profound sense of coherence within the universe of reason was not troubled, even when it was once reported that a colleague had said there was something odd about our university: it had two faculties devoted to something that did not exist: God. That even in the face of such radical scepticism it is still necessary and reasonable to raise the question of God through the use of reason, and to do so in the context of the tradition of the Christian faith: this, within the university as a whole, was accepted without question.
I was reminded of all this recently, when I read the edition by Professor Theodore Khoury (Münster) of part of the dialogue carried on - perhaps in 1391 in the winter barracks near Ankara - by the erudite Byzantine emperor Manuel II Paleologus and an educated Persian on the subject of Christianity and Islam, and the truth of both.  It was presumably the emperor himself who set down this dialogue, during the siege of Constantinople between 1394 and 1402; and this would explain why his arguments are given in greater detail than those of his Persian interlocutor.  The dialogue ranges widely over the structures of faith contained in the Bible and in the Qur'an, and deals especially with the image of God and of man, while necessarily returning repeatedly to the relationship between - as they were called - three "Laws" or "rules of life": the Old Testament, the New Testament and the Qur'an. It is not my intention to discuss this question in the present lecture; here I would like to discuss only one point - itself rather marginal to the dialogue as a whole - which, in the context of the issue of "faith and reason", I found interesting and which can serve as the starting-point for my reflections on this issue.
In the seventh conversation (διάλεξις- controversy) edited by Professor Khoury, the emperor touches on the theme of the holy war. The emperor must have known that surah 2, 256 reads: "There is no compulsion in religion". According to some of the experts, this is probably one of the suras of the early period, when Mohammed was still powerless and under threat. But naturally the emperor also knew the instructions, developed later and recorded in the Qur'an, concerning holy war. Without descending to details, such as the difference in treatment accorded to those who have the "Book" and the "infidels", he addresses his interlocutor with a startling brusqueness, a brusqueness that we find unacceptable, on the central question about the relationship between religion and violence in general, saying: "Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached.”  The emperor, after having expressed himself so forcefully, goes on to explain in detail the reasons why spreading the faith through violence is something unreasonable. Violence is incompatible with the nature of God and the nature of the soul. "God", he says, "is not pleased by blood - and not acting reasonably (σὺν λόγω) is contrary to God's nature. Faith is born of the soul, not the body. Whoever would lead someone to faith needs the ability to speak well and to reason properly, without violence and threats... To convince a reasonable soul, one does not need a strong arm, or weapons of any kind, or any other means of threatening a person with death...". 
The decisive statement in this argument against violent conversion is this: not to act in accordance with reason is contrary to God's nature.  The editor, Theodore Khoury, observes: For the emperor, as a Byzantine shaped by Greek philosophy, this statement is self-evident. But for Muslim teaching, God is absolutely transcendent. His will is not bound up with any of our categories, even that of rationality.  Here Khoury quotes a work of the noted French Islamist R. Arnaldez, who points out that Ibn Hazm went so far as to state that God is not bound even by his own word, and that nothing would oblige him to reveal the truth to us. Were it God's will, we would even have to practise idolatry. 
At this point, as far as understanding of God and thus the concrete practice of religion is concerned, we are faced with an unavoidable dilemma. Is the conviction that acting unreasonably contradicts God's nature merely a Greek idea, or is it always and intrinsically true? I believe that here we can see the profound harmony between what is Greek in the best sense of the word and the biblical understanding of faith in God. Modifying the first verse of the Book of Genesis, the first verse of the whole Bible, John began the prologue of his Gospel with the words: "In the beginning was the λόγος". This is the very word used by the emperor: God acts, σὺν λόγω, with logos. Logos means both reason and word - a reason which is creative and capable of self-communication, precisely as reason. John thus spoke the final word on the biblical concept of God, and in this word all the often toilsome and tortuous threads of biblical faith find their culmination and synthesis. In the beginning was the logos, and the logos is God, says the Evangelist. The encounter between the Biblical message and Greek thought did not happen by chance. The vision of Saint Paul, who saw the roads to Asia barred and in a dream saw a Macedonian man plead with him: "Come over to Macedonia and help us!" (cf. Acts 16:6-10) - this vision can be interpreted as a "distillation" of the intrinsic necessity of a rapprochement between Biblical faith and Greek inquiry.
In point of fact, this rapprochement had been going on for some time. The mysterious name of God, revealed from the burning bush, a name which separates this God from all other divinities with their many names and simply asserts being, "I am", already presents a challenge to the notion of myth, to which Socrates' attempt to vanquish and transcend myth stands in close analogy.  Within the Old Testament, the process which started at the burning bush came to new maturity at the time of the Exile, when the God of Israel, an Israel now deprived of its land and worship, was proclaimed as the God of heaven and earth and described in a simple formula which echoes the words uttered at the burning bush: "I am". This new understanding of God is accompanied by a kind of enlightenment, which finds stark expression in the mockery of gods who are merely the work of human hands (cf. Ps 115). Thus, despite the bitter conflict with those Hellenistic rulers who sought to accommodate it forcibly to the customs and idolatrous cult of the Greeks, biblical faith, in the Hellenistic period, encountered the best of Greek thought at a deep level, resulting in a mutual enrichment evident especially in the later wisdom literature. Today we know that the Greek translation of the Old Testament produced at Alexandria - the Septuagint - is more than a simple (and in that sense really less than satisfactory) translation of the Hebrew text: it is an independent textual witness and a distinct and important step in the history of revelation, one which brought about this encounter in a way that was decisive for the birth and spread of Christianity.  A profound encounter of faith and reason is taking place here, an encounter between genuine enlightenment and religion. From the very heart of Christian faith and, at the same time, the heart of Greek thought now joined to faith, Manuel II was able to say: Not to act "with logos" is contrary to God's nature.
In all honesty, one must observe that in the late Middle Ages we find trends in theology which would sunder this synthesis between the Greek spirit and the Christian spirit.
This inner rapprochement between Biblical faith and Greek philosophical inquiry was an event of decisive importance not only from the standpoint of the history of religions, but also from that of world history - it is an event which concerns us even today. Given this convergence, it is not surprising that Christianity, despite its origins and some significant developments in the East, finally took on its historically decisive character in Europe. We can also express this the other way around: this convergence, with the subsequent addition of the Roman heritage, created Europe and remains the foundation of what can rightly be called Europe.
The thesis that the critically purified Greek heritage forms an integral part of Christian faith has been countered by the call for a dehellenization of Christianity - a call which has more and more dominated theological discussions since the beginning of the modern age.
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.
And so I come to my conclusion. This attempt, painted with broad strokes, at a critique of modern reason from within has nothing to do with putting the clock back to the time before the Enlightenment and rejecting the insights of the modern age. The positive aspects of modernity are to be acknowledged unreservedly: we are all grateful for the marvellous possibilities that it has opened up for mankind and for the progress in humanity that has been granted to us. The scientific ethos, moreover, is - as you yourself mentioned, Magnificent Rector - the will to be obedient to the truth, and, as such, it embodies an attitude which belongs to the essential decisions of the Christian spirit. The intention here is not one of retrenchment or negative criticism, but of broadening our concept of reason and its application. While we rejoice in the new possibilities open to humanity, we also see the dangers arising from these possibilities and we must ask ourselves how we can overcome them. We will succeed in doing so only if reason and faith come together in a new way, if we overcome the self-imposed limitation of reason to the empirically falsifiable, and if we once more disclose its vast horizons. In this sense theology rightly belongs in the university and within the wide-ranging dialogue of sciences, not merely as a historical discipline and one of the human sciences, but precisely as theology, as inquiry into the rationality of faith.
Only thus do we become capable of that genuine dialogue of cultures and religions so urgently needed today. In the Western world it is widely held that only positivistic reason and the forms of philosophy based on it are universally valid. Yet the world's profoundly religious cultures see this exclusion of the divine from the universality of reason as an attack on their most profound convictions. A reason which is deaf to the divine and which relegates religion into the realm of subcultures is incapable of entering into the dialogue of cultures. At the same time, as I have attempted to show, modern scientific reason with its intrinsically Platonic element bears within itself a question which points beyond itself and beyond the possibilities of its methodology. Modern scientific reason quite simply has to accept the rational structure of matter and the correspondence between our spirit and the prevailing rational structures of nature as a given, on which its methodology has to be based. Yet the question why this has to be so is a real question, and one which has to be remanded by the natural sciences to other modes and planes of thought - to philosophy and theology. For philosophy and, albeit in a different way, for theology, listening to the great experiences and insights of the religious traditions of humanity, and those of the Christian faith in particular, is a source of knowledge, and to ignore it would be an unacceptable restriction of our listening and responding. Here I am reminded of something Socrates said to Phaedo. In their earlier conversations, many false philosophical opinions had been raised, and so Socrates says: "It would be easily understandable if someone became so annoyed at all these false notions that for the rest of his life he despised and mocked all talk about being - but in this way he would be deprived of the truth of existence and would suffer a great loss".  The West has long been endangered by this aversion to the questions which underlie its rationality, and can only suffer great harm thereby. The courage to engage the whole breadth of reason, and not the denial of its grandeur - this is the programme with which a theology grounded in Biblical faith enters into the debates of our time. "Not to act reasonably, not to act with logos, is contrary to the nature of God", said Manuel II, according to his Christian understanding of God, in response to his Persian interlocutor. It is to this great logos, to this breadth of reason, that we invite our partners in the dialogue of cultures. To rediscover it constantly is the great task of the university.
 Of the total number of 26 conversations (διάλεξις – Khoury translates this as “controversy”) in the dialogue (“Entretien”), T. Khoury published the 7th “controversy” with footnotes and an extensive introduction on the origin of the text, on the manuscript tradition and on the structure of the dialogue, together with brief summaries of the “controversies” not included in the edition; the Greek text is accompanied by a French translation: “Manuel II Paléologue, Entretiens avec un Musulman. 7e Controverse”, Sources Chrétiennes n. 115, Paris 1966. In the meantime, Karl Förstel published in Corpus Islamico-Christianum (Series Graeca ed. A. T. Khoury and R. Glei) an edition of the text in Greek and German with commentary: “Manuel II. Palaiologus, Dialoge mit einem Muslim”, 3 vols., Würzburg-Altenberge 1993-1996. As early as 1966, E. Trapp had published the Greek text with an introduction as vol. II of Wiener byzantinische Studien. I shall be quoting from Khoury’s edition.
 On the origin and redaction of the dialogue, cf. Khoury, pp. 22-29; extensive comments in this regard can also be found in the editions of Förstel and Trapp.
 Controversy VII, 2 c: Khoury, pp. 142-143; Förstel, vol. I, VII. Dialog 1.5, pp. 240-241. In the Muslim world, this quotation has unfortunately been taken as an expression of my personal position, thus arousing understandable indignation. I hope that the reader of my text can see immediately that this sentence does not express my personal view of the Qur’an, for which I have the respect due to the holy book of a great religion. In quoting the text of the Emperor Manuel II, I intended solely to draw out the essential relationship between faith and reason. On this point I am in agreement with Manuel II, but without endorsing his polemic.
 Controversy VII, 3 b–c: Khoury, pp. 144-145; Förstel vol. I, VII. Dialog 1.6, pp. 240-243.
 It was purely for the sake of this statement that I quoted the dialogue between Manuel and his Persian interlocutor. In this statement the theme of my subsequent reflections emerges.

 Regarding the widely discussed interpretation of the episode of the burning bush, I refer to my book Introduction to Christianity, London 1969, pp. 77-93 (originally published in German as Einführung in das Christentum, Munich 1968; N.B. the pages quoted refer to the entire chapter entitled “The Biblical Belief in God”). I think that my statements in that book, despite later developments in the discussion, remain valid today.
