The role of solidarity in the quest for the sustainable improvement of the material and spiritual living conditions of people and planet earth

This article focuses on contemporary challenges to solidarity. The author starts by outlining the paradoxes of solidarity, concerning the existence in the world of both an excess and a deficit of solidarity in the material and spiritual spheres of human life. The aim of the article is to try to identify ways to overcome these paradoxes. The Church’s social doctrine is intended to help in this task.
