Please note that the Ethiopian has only one jurisdiction on earht and it is recognised worldwide.
Patriarch Paulus is its Patriarch
The canonical title of the Head of the Indian Church (Eastern Syrian Church), in the succession of Apostle Thomas is 'Catholicos of the East'. In India, there is only one legally recognized Catholicos of the East, H.H. Didymus 1, head of the Malankara Orthodox Syrian Church (also known as Indian Orthodox Church). It is a combination of two titles - Catholicos of the East and Malankara Metropolitan.
After having reached a compromise with the head of the Indian Church, i.e the Catholicos of the East and Malankara Metropolitan, the head of Jacobite faction (Metropolitan Thomas Mar Dionysius) was forced by some extremist Jacobite people to go to Patriarch in Damascus and get the title as Catholicos. He was given the title 'Catholicos of India'. This is a very new title created only in 2002, to satisfy the extremists. Earlier the Patriarch himself had made a decree to accept the Supreme Court decision and work for unity. These extremists are also supported by some of the SOC bishops, including the Bishop of the Eastern Diocese of SOC in USA. This is why in Eastern USA, OO concelebrations happen in a special way, which is not normal among Oriental Orthodox. How can the SOC bishop of Esstern USA who is speaks against the Indian Church (I have read in newspaper an address made by the bishop when he was invited by a Jacobite Church) and encouraging people of Jacobite group to fight against the Indian Church invite the Indian Church?
I must add that not all SOC bishops are against the Indian Church. This circumstance is special in the USA. In Western USA a group of Syrians accepted the Indian Church. Recently in the Eastern USA also two congregations accepted the Indian Church.
Indian Supreme Court had requested both groups to unite in 2002 through a united council under the supervision of Supreme Court appointed counsel. The extremist section of the Jacobite group (headed by Bishop Thomas Mar Dionysius) boycotted the meeting. Another section accepted to remain united. The group separated from the Indian Church is supported by Patriarch in Damascus and the Patriarch gives illegal ordination to Indian candidates without consulting with the Catholicos of the East. This is violation of both law and canon. Normally ordinations in the Indian Church are approved by the Synod headed by the Catholicos of the East, the canonical head.
Just like Abune Paulus is the legitimate Patriarch, there is only one legitimate 'Catholicos of the East' and 'Malankara Metropolitan' recognized in India. It is a combination of two titles - Catholicos of the East and Malankara Metropolitan. Perhaps this is similar to Patriarch of Ethiopian Church is also the Echege of the See of St. Tekle Heimanot. It is very traditional for us. Canonically Cathoilicos of the East is in the succession of Apostle Thomas, the Apostle of the East. But the Jacobite extremists deny this. They claim Patriarch of Antioch is the supreme universal head and the Indian Church is a mere subordinate. This model is not recognized in the See of Catholicos of the East. They are trying to revive a temporary reduction that existed many years back, called the 'Mafrian'.
I do not know why rest of OO in Eastern Diocese of USA is not considering the canonicity of the title 'Catholicos of India', the new title instituted in 2002 against the legal 'Catholicos of the East'.
Their Malankara Jacobite bishop in USA was not legally ordained. He was not recognized by the Synod of Catholicos of the East. He was sent to Damascus to be ordained by the Catholicos of India, head of the Jacobite group. The contradicting aspect is that the Malankara Diocese of Jacobite Church in USA is not under their head (Catholicos of India, head of Jacobite group) in India, but he is directly under Patriarch in Damascus. It is very complicated system they follow, all with the aim of causing many divisions in the Indian Church.
I request Oriental Orthodox brothers to sincerely study this complicated matter, before making comments like 'Indian Church is excommunicated by SOC' etc.
