Modern text research shows that biblical tradition often does not at all correspond to real historical events. This lessens neither the inner significance of the Bible nor of true Christendom, for, true Christendom is more than just a religion: It is the spiritual Sphere of Life that embraces all Worlds with all their Mysteries. Some results of modern research as collected and presented here in a dense form,clearly contradict canonical narratives, and might provoke different reactions: from condescendent shaking of heads to apalled outcries. But neither will diminish their validity. After 2000 years of nominal Christianism it is now time to animate truly spiritual Christendom. This new Christendom is, on one side, a renewal of the classical antique Mysteries, with the Christ Jesus as the last and greatest Avatar of the "Sun Spirit descended to Earth" as the "Redemptor of theWorld", and on the other, a complete renewal of religious thinking and feeling of humans, everyone now being summoned to realize their potential "microcosmical Cristos" in today's spiritual freedom with its world-wide new paradigmata. The two texts published here in best possible accuracy, are especially important because, combined with a deeply founded introduction, they at last publicly present the world of faith of the true Arch-Christians of the first centuries, and their comprehension of events "from Bethlehem to Golgotha". Based on said insights, the book here in hand undertakes to define a new Christendom for a new Era: A Christendom that must not just be believed in sheepish obedience, but lived out of mature consciousness and in a daily effort of every single human. Its purpose is to encourage a large number of people to experience this new Light, Truth and Life. Numerous book-references, many in part extensive notes, and a number of full-page images show the credibility of the new view, and enlarge the usual dogmatic picture.- A book that, read in a leisurly pace and with open soul and heart , may bring about new clarity and a new vivid faith for the old message.
