President Andrzej Duda on Wednesday attended the Orthodox Lord's Transfiguration ceremony on the Holy Mount of Grabarka (north-eastern Poland).
President Duda said that one of the most important tasks facing the president was to seek "common elements" uniting the Polish people, irrespective of their religion and nationality.
"I believe that we will manage to build a community despite existing differences. Mutual respect is of utmost significance even if there are differences. Let me pay my respects to all Poles today," the president said and expressed thanks for "the possibility of taking part in celebrations on the site which is a holy place for the Orthodox Church."
Duda stressed that the Polish president should respect all sites and traditions which were important to Poland and its citizens.
Head of the Orthodox Church in Poland Archbishop Sawa said that today's society should be constantly reminded of Christian values.
"Today's secularisation creates many dangers and makes each of us face various pathologies, namely hatred, terrorism as well as a moral and spiritual crisis," the archbishop said.
Also present was a delegation of the Greek Orthodox Church headed by the Corfu Metropolitan Bishop Nectarios. It came to Poland with the relics of Saint Spyridon from Corfu.
According to police estimates, the two-day ceremonies were attended by over 10,000 people.
The Holy Mount of Grabarka is considered the holiest location in Poland for Orthodox Christians. It is the site of the Church of the Transfiguration of the Lord and is home to the women's convent of Ss. Martha and Mary. The most prominent and well-known feature of Grabarka is the forest of crosses surrounding the church, all brought to the Mount by pilgrims.
Grabarka has been a centre of pilgrimage for Orthodox Christians from Poland and other countries since the 18th century.
The Orthodox Church in Poland estimates the number of its faithful at 450,000-500,000. In the latest national census some 156,000 Poles declared they were Orthodox Christians. (PAP)
