When the re-unified Malankara Association met at Niranam on 17 May 1962, Augen Thimotheos was elected as the successor-designate to the Catholicos of the East Baselios Geevarghese II. Following the demise of Geevarghese II, Thimotheos took charge as the Malankara Metropolitan. On 22 May 1964, Thimotheos was installed formally as Catholicos Baselios Augen I by the visiting Patriarch of Antioch Ignatius Ya`qub III who had arrived in response to the invitation of the Malankara Synod.
