His Beatitude Baselios Poulose II was born on 12 June1914, as the second son of Mrs. Elizabeth and Rev. Fr. Joseph Puthussery, at Cherai.

On 19 October 1952, Patriarch H. H. Moran Mor Ignatius Aphrem I ordained Kassisso Poulose as Metropolitan with the name ‘Mor Philoxenos’ at the Patriarchal Cathedral in Homs, Syria.
Fulfilling the wishes of countless people of faith in India, the Patriarch of Antioch, H. H. Moran Mor Ignatius Yaqub III consecrated Poulose Mor Philoxenos as the Catholicos of the East, under the title ‘Mor Baselios Poulose II’ on 7th September 1975 at the Patriarchal Cathedral in Demascus. His Beatitude was officially elected as the Malankara Metropolitan at the meeting of the church delegates held on 26th December 1975 at Thuruthissery. His Beatitude made history by consecrating Mor Saverious Zakka, Archbishop of Baghdad, as the Patriarch of Antioch and all the East on September 14, 1980. This was the first time in the annals of the Syrian Orthodox Church that a Catholicos from Malankara officiated the ordination of a Patriarch of Antioch. His Beatitude along with H.H.

The funeral service of Bava Thirumeni on the following day, was attended by thousands of people; a testimony to the affection and esteem that He commanded in the Church and in the society at large. In accordance with His last wish, the mortal remains of the Catholicos Mor Baselios Poulose II were interned in a tomb in Malecruz Dayronear Puthencruz, in Ernakulam District. His Beatitude was widely revered for his simplicity, his ascetic life and spartan routine. He was a true Indian citizen in culture, a true Antiochean in tradition and a true Christian in faith. His profound scholarship in Sanskrit helped him know and retain the ethos of Indian culture. Bava Thirumeni was a great scholar in Theology and in Syriac, and an appealing orator in Syriac, English and Malayalam.
Bava Thirumeni was also a true lover of nature and enjoyed walking across the farm, nursing plants. The humility and hospitality of this great visionary was experienced by all who visited His Beatitude. His noble and exemplary life will be an eternal source of inspiration to generations.
