1. Any attempt to rediscover the partly lost spiritual depths of Christianity must, of course, start with the teachings, life and significance of Jesus Christ himself and the early Christians - including their "apocalyptic" traits, instead of only picking out that which suits a given theology. It is also important to take the variety of the early Christians seriously, just as the evangelists****** did, in order to show the more comprehensive role of Christ.*

2. The Old Church of the following centuries was characterized by the authority of the extensive tracts of the "Fathers of the Church".  With the help of the Greek language and their learnedness they were able to make early Christian traditions much clearer for Europeans. They still knew a lot about older writings which are missing today. During this era there were also a lot of controversies concerning what corresponded to true Christianity and what did not. Many of these findings, which were ignored later, are worthy of new appraisal - especially in comparison with their origins. Furthermore, there were also Christians who didn’t primarily seek their salvation through a Church, but  through the individual access to God in prayer or meditation - e.g. in Egypt, cf. the finds of Naq Hammadi. In the "mystical theology" of today's Orthodox Churches some of it is well preserved.

3. Medieval scholasticism and canonical work led to a theological systemization through argument, counter-argument and conclusions - which one could call a philosophy of religion. The authority of the "Fathers of the Church" was still accepted, but only as far as they were in accordance with these thoughts. Although scholasticism produced a lot of useful food for thought at that time, the often one-sided absolutism and therefore exclusive intellectual logic was alarming and should be distinguished from the actual religious dimension. So beliefs were preserved in the form of doctrines or dogmas, but this also tempted people to follow inquisitorial practices. The creativity of today's spiritual seekers and mystics shows us that sometimes the same intellectual method could lead to other conclusions too and that real spiritual growth requires a consciousness, which is more flexible, more comprehensive, and less hardened. The strict scholastic method is still an important starting point for today's systematic theology, especially in Catholicism. But there is also a certain openness for other or ecumenical approaches (.e.g. Yves Congar). Indeed, the purpose cannot be a one-sided criticism of one of the theological schools. At an early stage of the work on the main text of "Ways of Christ", possible structures were considered. Only one possibility remained and that was to use the sequence of the "Steps of Jesus" taken from the Gospels themselves! There is also an archetypal sequence of stages of possible human development and areas of consciousness in relation to the surrounding world. But this is a new, interdisciplinary approach.

4. Once enough church tradition had been added to the origins, the efforts of the Reformation followed, in order to clearly take the biblical origins as the basis again. But they were limited in this endeavour because they themselves were children of their times and knew little about the spiritual and mystical movements in the early history of Christianity. They also abandoned some basically valuable traditions, - such as the Adoration of Mary. Only individuals like the German Protestant theologian J. V. Andreae published deeper experiences, which might be called "Christian esoteric" ones; disguised as a dream or novel for reasons of safety. Even Protestant Churches were not always as tolerant as one might think. So it is not easy to recognize the Christian nature of these experiences.
The Counter-Reformation, religious wars, etc. did the rest. But the various theological approaches were still similar in many points. Where one can find even within Protestant Churches separate denominations like the Lutheran and the Reformed ones, this separation is only valid for theological discussions and no longer supported by the members themselves (at least in Germany**.

5. The Age of new philosophy, Enlightenment, rationalism and (natural) science which followed did not result in a theology of spiritual experience complementary to the old intellectual systematic theology either. On the contrary, an increasing number of historical-critical (historiocritical) theologians began to orient themselves to the new intellectual and one-sided materialistic science of that time. Theology started to become a comparative study of literature and linguistic research  - which was not necessarily a mistake, but one-sided.  In contrast to that, contemporary exponents of the old systematic theology saw themselves again as a kind of centre of actual theology, around which the newer fields of research might group themselves. Their ability, however, to fulfil this integrative role was questionable. Surely it would be legitimate to relate the manifold scientific discoveries to theological teachings - as long as it does not lead to new scientific dogmas. But consequently one would expect this to take place today too. In most cases this did not happen. This would mean considering the emerging new world view and paradigm, stemming from the new scientific schools of quantum physics, quantum biology, new geophysics, astrophysics and especially new sciences like parapsychology - which don't back up the old materialism. It is useless to adapt today's theology to a scientific world view of the 19th century!***
In contrast to the tendencies of rationalism, new revivalist movements have also come into existence since the 19th century, leading to many new Protestant Free Churches. They did not, however, find it necessary to examine scientific development to see whether it matches up with their current beliefs. They promote biblical beliefs. In most cases they would not call this "theology" at all, but it is indeed a certain kind of theological interpretation (exegesis) of the Bible.

6. So in the 20th century many efforts were made to add facets of theology which had not previously been given enough consideration, but still without the mystical and spiritual dimension - at least recognized as necessary by Karl Rahner. Such trials in the Catholic and Protestant worlds were good for parts of the society, because they addressed the real problems of the people: e.g. Karl Barth; the political theology and the theology of liberation in the Third World and the theology of creation ****), feminist theology. Some schools, such as the "Entmythologisierungstheologie" (theology of demythologization) of Bultmann did more harm than good, almost reducing the belief to a rationalistic world view - although they state correctly that Faith does not need scientific objectivication. Drewermann then tried an exegesis of the Gospels with depth psychology. This might be a bridge for leaving the world of a materialistic world view without a soul, but depth psychology is not yet the real spiritual dimension of the Bible and so it is of no use to play these areas off against each other, as it happened. 
Until now, problems between fundamentalism and relativism have dominated the discussion.
Apart from that, the so called "Jesus disclosure stories" outside of theological circles over the last few years have been detrimental to the present discussion.

7. Till now, there has not been anything resembling a "post-modern" theology of the 21st century. Renewing the spiritual possibilities of Christianity - keeping the old depth of faith and social watchfulness as well requires a more comprehensive change in consciousness*****. Spiritual precision and differentiated ways of looking at society and the world are called for here, instead of only administrating and perpetuating the old fields of theological research and scientific study of religion: a way to "full" Christianity without the fragmentation of today. This is where "Ways of Christ" comes in.

*) They consciously accepted not only that "source Q", which researchers found within it. (It only contained sayings of Jesus before the Passion, with ethics beyond many social conventions, often connected, e.g. with the Sermon on the Mount. The similar and so also authentic sayings of the "Gospel of Thomas" shows that - depending on the preachers and the audience - further sayings of Jesus were in circulation. At first, only a few disciples were able to go along with the last steps in the life of Jesus - starting with raising Lazarus from the dead - and so represent it authentically. Nevertheless it was revealed to the seekers.
**) At the present time, e.g. in Germany, there are attempts to clear up this situation. Furthermore, concerning the different Churches see also our page "The 7 Churches (of the Revelation) and today's Churches"
***) See also our extra page "Science and the belief in God". See Hans Küng, Christianity. Essence, History, Future for a study of the development of Christianity. He attempts an integrated research that accepts the contents of the Scriptures as a contextual source, in spite of archaeology and critical theological research, which gives some Christians and Jews pause for thought. (We don’t accept all the consequences resulting from the historico-critical research. For instance, some events surrounding Jesus appear largely to be only subjective experiences. However, Küng is open to an open, not yet explored kind of reality of such experiences. His interesting method of exploring steps in the development of Christianity in general (paradigms), cannot sufficiently recognize the significance of directions like the Mystics, which generally speaking, were never crucial until now. They have unearthed methods, which are very important for grasping the full potential of Christianity.
