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 (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 the experts, this is 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 which leaves us astounded, 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 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 logos". This is the very word used by the emperor: God acts, 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.
