(ANSA) - KRAKOW - ''Europe has deep Christian roots, if we cut these roots, the tree will die'', the Archbishop of Krakow, cardinal Stanislaw Dziwisz, said meeting with journalists from many European countries ahead of World Youth Day, scheduled for next July. ''We are fighting - Dziwisz added - to safeguard moral values and Christian roots, the foundation of Europe. We must be able to protect ourselves from destructive tendencies, even if Europe accuses us of being destructive''. Referring to the current political situation in Poland, Dziwisz underlined that even if there are problems, the Roman Catholic Church is not facing a crisis. ''There are differences between north and south, for example in terms of Mass attendance. We are concerned about the demographic decline, which is not due to poverty, but to the way of thinking'', he added. ''The Government supports population growth, for instance through the subsidy programme for families expecting second child. The WYD - he continued - is expected to simulate youth with regard to moral and religious values, both in Poland and in Europe''. As for European concerns about some policies developed by the Polish government, Dziwisz underlined that ''this is a free and sovereign country, that safeguards its freedom both in terms of ethics and politics''.
