Diocese of the Philippines and Vietnam

In March 2014, the five diocesan provinces of Sarangani, South Cotabato, Sultan Kudarat, North Cotabato and Maguindánao of the Philippine Independent Church (also known as Aglipayans), led by their two bishops Esteban Valmera and Rogelio Ringor together with thirteen other Aglipayan clergy petitioned Patriarch Kirill of Moscow and All Rus’ to accept their dioceses, totaling 28 parishes, into the Orthodox Church.[8] Inspired by their moves and motives, another Aglipayan group called the Aglipayan Christian Church under the leadership of their eight bishops and superiors, also petitioned to the Patriarch of Moscow that they also wished to bring their entire group to embrace the Orthodox faith.

The Moscow Patriarchate then responded by sending Russian Orthodox missionaries in order to catechize the groups wishing to convert.[9][10] Among the missionaries who came to the Philippines were Fr. Kirill Shkarbul from Taiwan,[11] Fr. Stanislav Rasputin and Fr. George Maksimov from Russia,[12] as well as lay missionaries Aleksei, Timothy and Sergei, from Russia, the United States and Ukraine, respectively.

The eparchy is one of the two canonical jurisdictions in the Philippines under the Patriarchate of Moscow, the other being the Philippine Mission of the Russian Orthodox Church outside Russia under the semiautonomous Russian Orthodox Church outside Russia.

On February 26, 2019, the Holy Synod formed the Diocese of Korea, the Diocese of Singapore, the Diocese of Thailand, and the Diocese of the Philippines and Vietnam within the Patriarchal Exarchate in South-East Asia and appointed Metropolitan Sergius as the ruling Bishop of the Singapore diocese and locum tenens of the other three dioceses.[13][14][4][7]

On 18 September 2014, the Moscow Patriarchate was registered with the government of the Philippines as the Philippine Orthodox Church (Moscow Patriarchate).[8] On 26 September 2014, the Philippine Orthodox Church Deanery of St. John the Baptist based in Ladol, Alabel, Sarangani was registered and on 29 September 2014, the Philippine Orthodox Church Deanery of the Mother of God and Ever Virgin Mary based in Aglipayan Village, Sto. Niño, Tugbok, Dávao was also registered.

In a meeting with Archbishop Sergius Chashin of Solnechnogorsk on 19 June 2017, Foreign-Affairs Secretary Alan Peter Cayetano pledged to help revive, through state power, services at the Ivī́rōn Church on Taft Avenue in Manila.[15]

On 28 December 2018, in response to the Ecumenical Patriarchate's actions in Ukraine,[16] the Holy Synod of the Russian Orthodox Church decided to create "a Patriarchal Exarchate in South-East Asia [PESEA] with the center in Singapore." The "sphere of pastoral responsibility" of the PESEA is Singapore, Vietnam, Indonesia, Cambodia, North Korea, South Korea, Laos, Malaysia, the Myanmar, the Philippines, and Thailand.[17][18][19][20][21] Archbishop Sergius (Chashin), was appointed as primate of the newly created PESEA, with the title "of Singapore and South-East Asia"[18][22][19] On the same day, in an interview with Russia-24 channel,[23] Metropolitan Hilarion, spokesman of the ROC, declared the ROC "will now act as if they [Constantinople] do not exist at all because our purpose is missionary, our task is to educate, we are creating these structures for ministerial care about our flock, there can be no such deterring factors here", and that the ROC will take charge of the Orthodox faithfuls of its diaspora instead of the Eumenical Patriarchate.[24][25] The Moscow Patriarchate aims to establish parallel jurisdictions all over the world without consultations with the Ecumenical Patriarchate, effectively competing with the latter.[26][27]

On 7 January 2019, during the evening service in the Church of Christ the Savior in Moscow, Patriarch Kirill elevated Archbishop Sergius (Chashin) to the rank of Metropolitan in connection with the latter's appointment as exarch of the PESEA.[28]

On 26 February 2019, the PESEA was divided into four dioceses that were created, of which the Diocese of the Philippines and Vietnam.[5][14][4]

20 September 2019, ROCOR mission in the Philippines was received to Diocese of the Philippines and Vietnam[29]

On February 22, 2020, Metropolitan Paul of Manila and Hanoi celebrated the great consecration of the Church of St. Seraphim of Sarov in Makalangot on the island of Mindanao, which became the first full-fledged church building in the diocese. On the same day, a first Diocesan Assembly of the clergy and laity of the Philippine-Vietnamese diocese was held was held there. Five deaneries within the diocese were established: deanerу of Manila, deanerу of Davao City, deanerу of General Santos, deanerу of Vietnam, and deanerу of Davao del Sur.[30][31]
