An analysis of the role of the social activity of a denominational organisation is not possible remotely and independently of the interpretation of its religious-philosophical justification from the perspective of the denomination itself. This study analyses the main concepts and categories of social doctrines of Catholics and Protestants, defining their role in the light of theological attitudes, and comparing them with similar concepts of other confessions. The publication is addressed to religious scholars, historians, theologians, political scientists, lawyers, teachers, postgraduates and students of educational institutions (state and non-state), scientific and human rights organizations, as well as state and municipal employees, liaising with religious organizations, and to all those interested in contemporary processes in the spiritual life of our society.pAn analysis of the role of the social activity of a denominational organisation is not possible remotely and independently of the interpretation of its religious-philosophical justification from the perspective of the denomination itself.
