The fact that Christian truth is symphonic should be spoken loudly, conveyed to the heart of everyone - today this is perhaps more necessary than ever. But a symphony is by no means a sweet and conflict-free harmony. Great music is always dramatic, it constantly builds and concentrates tension - and resolves it at an ever-higher level. However, dissonance is not the same as cacophony. But this is not the only way to create and maintain symphonic tension... In the first part of this book we will - in a free form of an overview - outline the various aspects of theological pluralism, always keeping in mind its focus and source - Christian revelation. In the second part, some examples will show how diversity constantly flows out of unity, which has its justification in this unity and can always be integrated into it again.
