Abstract
This paper deals with the encyclical Fratres omnes (2020) not from the perspective of theology and its strictly religious implications, but in order to grasp those aspects uniting believers and non-believers. The focus is on those elements which, in order to oppose the global nihilistic drift of the homo oeconomicus, may support the development of new ways of relating human beings to each other and to the world. Within this frame, a special attention will be devoted to the concepts of ‘solidarity’ and ‘brotherhood’ which, aimed at overcoming the individualistic logic of profit, can contribute to an alternative cultural paradigm oriented to ‘existential’ peace.
