There is necessity to sort out in lucid way the problem of relationship between the mission of the Church and execution of policy tasks, especially social policy. This is absent subject in the contemporary discourse on the social sciences. The important fact is that social policy objectives involve people belonging to the Church, who motivate their engagement by Christian axiology. The Church as an institution of salvation isn’t directly involved in the practice of social policy. It can’t be treated just as one of its objects. The Church is not included and doesn’t want to be associated with social policy. However, the object’s social policy belong in some way to the religious organizations and those are catholic, if they undertake social tasks. If a significant percent of citizens belongs to the Church, in obvious reasons, it renders important influence on political decisions through its members, who are active in political parties, NGO’s and other associations and institutions. That is why catholic social teaching postulates that the church’s presence in social policy was characterized by an evangelical testimony.
Key words: social policy, catholic social science, subjects of the social policy, non-governmental organizations (NGO), civil society, political engagement, evangelization
