The thesis of this contribution – resulting from an oral presentation in the City of Bochum where I have lived since 2017 – , focuses on the connection between the dramatic loss of members in the Christian Churches in Europe on the one hand and the preoccupation with the relevance of “religious” feelings in the society on the other side, detected and elaborated by sociologists like Latour, Joas, Rosa. This approach seems – for me – to be very near to the project of “Weltbeziehung” which promotes some approaches in the Max Weber Institute. My intention is to identify and discuss some of the roots of this contemporary “religious” sensitivity in the medieval tradition of mysticism and especially in the literary reception of Meister Eckhart in the first half of the 20th century.
