I know there are Eastern Orthodox Churches in the Philippines (Greek and Antiochian Orthodox.) Filipinopilgrim and Sohma_hatori are two members here who are Eastern Orthodox, and they live in the Philippines.
Oriental Orthodox includes the Coptic, Ethiopian, Eritrean, Syriac, Indian, and Armenian Orthodox Churches. I'm not sure if there are Oriental Orthodox parishes or missions in the Philippines. I would think that if any of our Churches were involved there, it would be the Coptic Church, since they are very active in Australia and seem to have a presence in that area of the globe. Maybe one of our Coptic brothers can look into it and see if there is a Coptic mission over there.
