Before the Liturgy in the Church of the Assumption of Mary, Metropolitan Epifaniy led the Sunday Matins service as an honored spiritual guest.
At the end of the Divine Liturgy, which lasted four hours and was broadcast on Greek television, the Primate of the Orthodox Church of Ukraine addressed the Ecumenical Patriarch, the Archbishop of Athens and All Greece, the Metropolitan of Philippi, Naples and Thassos and all those present, expressing his gratitude for the joy of witnessing the unity of the Christ's Church, which was confirmed in the Sacrament of the Eucharist. The full text of the address in Ukrainian and Greek can be found here.
Ecumenical Patriarch Bartholomew addressed the congregants and all attendees. He devoted a significant part of his speech to Ukraine, condemning Russia's unjust and cruel war against our country. The Patriarch also criticized those who continue to sow division and doubts among the Orthodox despite the clear, consistent and canonically justified decisions of the Ecumenical Patriarchate regarding Church issues in Ukraine.
Per the Greek tradition, Metropolitan Epifaniy of Kyiv and All Ukraine distributed antidoron at the end of the Divine Liturgy.
During the two days of the visit, the Primate of the Russian Orthodox Church also had separate bilateral meetings with the Ecumenical Patriarch Bartholomew and the Archbishop of Athens and All Greece Ieronymos. At those meetings, the hierarchs discussed issues of countering Russian aggression and condemning the head of the Russian Orthodox Church, Kirill Gundyaev, for supporting the crimes of the Kremlin authorities against the Ukrainian people and spreading the heretical ethno-phyletic ideology of the "Russian World".
Patriarch Bartholomew and Archbishop Ieronymos testified to the unwavering support of the Ukrainian people and the Orthodox Church of Ukraine in these times of trials and suffering caused by Russia's war against Ukraine.
