Pope Francis warned ideological attempts to sow fear or division in society on Sunday as he paid tribute to Christians in Romania killed or persecuted under Communism.
His comments came on the final day of his visit too the majority-Orthodox country.
Francis travelled to the central city of Blaj to beatify seven bishops who died under the former Communist regime, either in prison or as a result of harsh treatment.
After the Second World War, Romanian authorities confiscated property from the Eastern Rite Catholic Church and forced its members to join the larger Orthodox Church, which was easier for party officials to control.
Looking tired from his schedule, the Pope beatified the bishops at an open-air mass, moving them one step closer to sainthood.
