Fr C.M. Thomas was elected to the episcopate by the Malankara Jacobite Syrian Christian Association meeting at Karingachira St. George Church in January 1974 and was consecrated, under the name of Mor Dionysius, metropolitan of the Angamali Diocese, the largest Syriac Orthodox diocese, by Mor Ignatius Ya`qub III on 24 February 1974 at Damascus along with Geevarghese Mor Gregorios (Perumpally Thirumeni). The two metropolitans played a significant role in leading the church during the crisis of the seventies. After the passing away of Mor Gregorios Geevarghese in February 1999, Mor Dionysius assumed the Presidency of the Malankara Syrian Orthodox Church Synod and was elected Catholicos-Designate at the delegates meeting held at Puthenkurishu on 27 December 2000 and again by the Jacobite Syrian Christian Association constituted under the newly formed constitution on 6 June 2002.[1]
