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.

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. Viewed more closely, three stages can be observed in the programme of dehellenization: although interconnected, they are clearly distinct from one another in their motivations and objectives.
Dehellenization first emerges in connection with the postulates of the Reformation in the sixteenth century. Looking at the tradition of scholastic theology, the Reformers thought they were confronted with a faith system totally conditioned by philosophy, that is to say an articulation of the faith based on an alien system of thought. As a result, faith no longer appeared as a living historical Word but as one element of an overarching philosophical system. The principle of sola scriptura, on the other hand, sought faith in its pure, primordial form, as originally found in the biblical Word. Metaphysics appeared as a premise derived from another source, from which faith had to be liberated in order to become once more fully itself. When Kant stated that he needed to set thinking aside in order to make room for faith, he carried this programme forward with a radicalism that the Reformers could never have foreseen. He thus anchored faith exclusively in practical reason, denying it access to reality as a whole.
