Every church in India has the right to claim this then, Why just Independent Indian Church? And where was this throne of St. Thomas hiding up untill 1932. Even the Supreme court of India officially declared that the Throne of St. Thomas is INVALID
You are right. Indian consitution allows the freedom and that is why the church owing allegiance to the hierarchy currently occupying Damascus seprated from the mother Church and registered itself as a new Church with the official title "Malankara Jacobite Syrian Church". - using a title 'Jacobite' which was rejected by Orthodox fathers. Suppose say, the Jacobites existed in another nation, where freedom of religion is not there, I don't think you can easily seperate and register a new Church as it happened in 2002.
As for Apostle Thomas, we breath this faith. All our families trace their origin to an ancestor baptised by Apostle Thomas. We have 2000+ years old faith in Apostle Thomas.
Indian Church existed with out any foreign intrusion until 17th century. It was only in the 17th century our fathers requested help against persecution by other foreign churches. Those who blindly believed any falsehood promoted by foreign churches seperated from the mother Church. But those who enquired the truth and accepted only true fathers remained united. Our Church is grateful to all Orthodox fathers who helped the Church with true teaching and include their names in the calendar of saints.
Indian Supreme Court can decide the legitimate Malankara Metropolitan (due to the administrative aspect of this position) based on majority voting by representatives from each parish in the Malankara Association. But the Apostolic throne of St. Thomas is a spiritual belief and it is not the court deciding matters of faith. "Apostolic Throne of St. Thomas' is inscribed in an ancient church.
It is also the canonical succession in the East according to Hudaya canon, the succession which begins with Apostle Thomas. So, the throne of St. Thomas is canonical. Only the Holy Synod has the authority to interpret faith (according to the consitution of 1934).
