The main purpose of the paper is to analyze the transfo rmations of the idea of brotherhood in Christian and secular thought and its impact on the current development and social policy of the EU. The paper shows the differences between Catholic and secular approaches to the idea brotherhood. A renewed concept of brotherhood for the UE needs to change the utilitarian background and turn to the selfless attitude towards other human beings and communities in need. The above thesis is located in political philosophy, partially in theology and public policy.
