was born to Ulahanan and Naithi of Kallaserri family in Kurichi, Kottayam on 16 June 1874. On 24 April 1892, Kadavil Paulose Mar Athanasios ordained him as deacon and on 24 November and 27 November 1898 he was ordained as priest and Ramban respectively by Parumala Mar Gregorios.His Holiness Beselius Geevarghese II
As per the order of Parumala Thirumeni", he resided in Kadambanad church and took charge of the southern dioceses. He also served as Manager and Malpan of Old Seminary. He published books like "Sahodaranmarude Charithram". "Rehasya Prarthanakal". "Parudaisa", and "Mar Yuhanon Mamdana".
On 8 September 1912, His Holiness Patriarch Abdhedh Meshiah consecrated him as Metropolitan Geevarghese Mar Gregorios at Parumala Seminary. He was appointed as the Metropolitan of Thumpamon, Kollam and Niranam dioceses. On 15 February 1929. With the Malankara Metropolitan Vattaserril Geevarghese Mar Dionysios as the chief priest, he was installed as the Catholicose of the East.
When the Association met on 24 December 1934 at M. D. Seminary, Kottayam, he was chosen as Malankara Metropolitan. It was a period when issues became very complex. Through prayer and fasting he received strength from God to lead his people for long years, courageously, inspiring his people to work for their church and for the glory of God. Following the peace pact of 1958, he had the good fortune to guide the destiny of the unified Malankara Church.
Apart from consecrating twelve Metropolitans, and ordaining more than thousand priests and deacons, he founded and consecrated many churches. On 22 April 1932 and on 20 April 1951 he conducted the 'Mooran Koodasha' at the Old Seminary. On 2 November 1947 he declared Parumala Mar Gregorios and Yeldo Mar Baselios as Saints.
From his time onwards the offices of Catholicose and Malankara Metropolitan came to repose in one and the same person. Shedding luster like a Beacon illuminating the history of the church, he led it from glory to glory. He entered the eternal realms on 3 January 1964 at Develokam Aramana He was laid to rest beside the Devalokam Aramana Chapel. His Anniversary is 3 January.
The Malankara Church Synod, consisting of Vattasseril Mar Dionysius and Mar Ivanios of Bethany installed Kallasseril Mar Gregorios (the then Metropolitan of Kollam, Thumpamon and Niranom) as the third Catholicose of the East with the title Baselios Geevarghese II. On the day following the installation, new Catholicose consecrated two metropolitans:- Kuriakose Mar Gregorios (Pampady) for the Kottayam Diocese and Mar Theophilos (who later on joined the Roman Church) in 1931. The Malankara Metropolitan, Vattasseril Mar Dionysius passed on February 23, 1934.
Catholicos Geevarghese II had a great desire to establish peace in the Church by bringing a rapprochement with the Patriarch. With this intent, the Catholicose, along with a delegation went over to Holmes in Syria and held discussions with the Patriarch. But the Patriarch was desirous of having authority over the Malankara Church. The Catholicose on his part was not ready to sacrifice the independence of his Church. Thus this trip to Syria undertaken by the Catholicose did not yield the desired results. After his return to Kerala, preparations were made for a meeting of the Malankara Association which is the parliament of the Church. In the absence of the Malankara Metropolitan, notice for the meeting was issued by the other Metropolitans and the members of the Managing Committee. The notice was sent to all the parish Churches in Malankara. The Association meeting at MD Seminary Kottayam in 1934 accepted the constitution of the Church. Till then there was no clear and definite constitution for the Church. The need for a constitution was long felt and preparations were on to codify it. Vattasseril Mar Dionysius had appointed a Committee to go into it. The Church constitution passed in 1934 was prepared by this Committee. It was a landmark in the history of the Malankara Church. The 1934 Malankara Association elected Catholicos Geevarghese II as Malankara Metropolitan also. Thus the two ecclesiastical positions - Catholicose and Malankara Metropolitan, wielding the spiritual, temporal and ecclesiastical authority in Malankara synchronised in the same parson.
In order to replenish the financial position of the Church, a Church Welfare Fund called "Catholicate Fund" was inaugurated. Every year the 6th Sunday in the Great Lent was declared as the Catholicate Day and the collections from parish churches towards this fund was to be made on that day every year.
The Catholicose led the Malankara Church delegation to the Faith and Order Commission at Edinburgh in 1937. The Catholicose was given the place of honour among all the Church leaders, both of the East and the West and the western media gave adequate coverage to this visit of the Head of the Malankara Church to the West
