The thematic framework and focus of the exhibition is the „Global Ethic Idea“, i. e. the quest for common ethical values, norms and standards in the religions and the question of their significance for today’s world. This theme was launched in 1990 by Hans Küng in his book Projekt Weltethos (Engl. Global responsibility, 1991) and found concrete expression in the “Declaration towards a Global Ethic” which was drafted by Hans Küng and endorsed by the Parliament of the World's Religions in Chicago in 1993. Since then it has been expanded upon in numerous publications
 

The basis of the exhibition is above all Hans Küng’s unique multimedia project “On the trails of world religions” (1999), consisting of a seven-part television series available on videos, an illustrated book, and a CD-ROM, which together are aimed to provide a comprehensive introduction to the theme.
