In 2017, the Protestant Church in Germany presented the robot priest “BlessU2” to the participants of the Deutscher Kirchentag in Wittenberg. This generated a number of important questions on key themes of religion(s) in digital societies: Are robots legitimized and authorized to pronounce blessings on humans—and why? To answer such questions, one must first define the interrelationship of technology, religion and the human being. Paul Tillich (1886–1965) referred to the polarization of autonomy and heteronomy by raising the issue of theonomy: the first step on the way to critical research on representing the divine in robotic technology.
