In 2002, Mor Dionysius Thomas was enthroned as
Catholicos of India, taking the name Baselios Thomas I. During his leadership, he restructured the Angamali diocese into five regions and established new dioceses in Delhi, Bombay, Bangalore, Mylapore, and Idukki. He also established the churches headquarters, the Patriarchal Centre in
Puthencruz, Kochi, in 2004. A prominent figure in ecumenical dialogue, Mor Baselios Thomas I held discussions with the Roman Catholic Church and the Mar Thoma Syrian Church, maintaining friendships with figures like
Joseph Mar Thoma,
Cardinal Baselios Cleemis, and
Cardinal George Alenchery. He participated in meetings with both
Pope Francis and
Pope John Paul II and took a leading role in protests opposing court orders favoring the Malankara Orthodox Syrian Church. In 2019, he stepped down from his administrative role as Malankara Metropolitan but remained Catholicos at the request of Patriarch Ignatius Aphrem II, with
Mor Gregorios Joseph succeeding him as Malankara Metropolitan. == Death ==
