On Tuesday, December 2, 2014, His All-Holiness visited Geneva, Switzerland, in order to deliver a formal address to eminent scientists and physicists at the invitation of the European Organization for Nuclear Research (CERN). The title of his address, which was delivered on Wednesday, December 3, was “The Interface of Science and Religion: Toward a Common Vision and Vocabulary”. The Ecumenical Patriarch received a guided tour by the General Director of CERN and Prof. Emmanuel Tsesmelis through the facilities of the institution as well as the world’s largest particle accelerator, which is located 100 meters underground. Established in 1954 and supported by twenty-one European nations, CERN is considered the “scientific heart of Europe” and is the largest such institution in the world, with 1,200 full-time employees. Accompanying His All-Holiness were Elder Metropolitan John of Pergamon, who participated in the conversation with scientists and researchers, as well as Third Patriarchal Deacon Theodoros Meimaris and Mr. Hrisovalandi Cavidis.
