Kudos🎉 to @Heritage Tale for this amazing work, some corrections listed below has to be noted: 0:19 Name of the church is " St. Thomas Orthodox Syrian Cathedral, Mulanthuruthy " 0:33 The church was established in 11th century whereas Malankara built bond with Church of Antioch only in 16th century. During 11th century Malankara church had formal connection only with Persian Catholicate. Finally Mulanthuruthy church is the native church of St. Gregorios of Parumala

I hope you read this. Nasranis, or Syriac Christians of Kerala split due to schism in the 16th century and the group that didn't join the Catholics came under the missionarries of the Syriac Orthodox church and decided to join them because the language of liturgy is the same. According to your video it says that the church was established under the Apostolic See of Antioch. That's not true at all. You can see the obvious Portuguese influences on the face of the Church itself.
