The aim of my article is to answer to the question about methods of maintaining of credibility of the Roman Catholic church in Poland (understood as an institution). My presentation will be based on the research which included analysis of content of the official and unofficial documents of Roman Catholic Church in Poland (between 2000-2008) concerning the social problems related to the political and economic modernisation in the context of European integration process, especially discussion about European Constitution. In my article I will concentrate on presentation one of the strategy, that is: dichotomisation of the reality on the clearly distinguished 'we' and 'they'. Peter Berger stressed that in this strategy religious institution perceived new, pluralistic world in the cathegories of the threat religious order.
