Paul Verghese's dedication to his job as a teacher and understanding of language and culture of the Ethiopians brought him to the attention of Emperor Haile Selassie.
He was enthroned during a holy mass conducted by senior Bishop Kuriakose Mar Clemis.
He was formally installed as the Cathlicos after a meeting of the Malankara Syrian Christian Association.
The court pointed out that the apex court in its final verdict in 2017, gave the Orthodox faction the right to administer 1,100 churches and parishes.
Mar Severios, 72, is currently the Metropolitan of the Diocese of Kandanad West and Diocese of Idukki.
The funeral services were held at the Catholicate Palace chapel at Devalokam in Kerala's Kottayam town.
The Metropolitan had been ailing for quite some time. Catholicos Paulose II was under treatment ever since he was diagnosed with cancer in January 2020.
His Holiness Moran Mor Baselios Marthoma Paulose II was one of the youngest metropolitans since His Holiness Mor Gregorius.
One of the church's major achievements was the Parumala Cancer Centre, which was set up at a cost of more than Rs 100 crore. He also launched a free cancer treatment programme for the poor.
Baselios Marthoma Paulose II was the first Metropolitan of Kunnamkulam diocese.
