Phulwar was the first village where the Jesuits stayed and explored the possibility of evangelization and the first baptisms were recorded from this village by Fr. John Killian SJ from October 9, 1932.

The missionaries acquired land in Poreyahat village, about 100 yards away from the present presbytery. There was a large house made of mud walls like that of a Santhal house. Slowly they added a big hall with mud walls to be used as a Church. The Jesuits toured over 45 villages and developed many Mass centers. In 1940, the Franciscans took over Poreyahat Mission from Fr. John Morrison SJ who was the last Jesuit to work in Poreyahat. In 1962 Fr. Peter Busch TOR constructed a new presbytery and stayed over there with his Assistant Priest Fr. Denis Kiro TOR and a Diocesan brother in regency, Br. Thomas Vetticad.

The newly built voluminous Parish Church was blessed on October 3, 1967 when the Silver Jubilee of four TOR fathers was celebrated. They were Late Bishop Urban McGarry TOR, Fr. Martin Brodhead TOR, Rev. Fr. Robert Herzer TOR and Fr. Maurice Buckly TOR. Together with the Silver jubilee, two diocesan priests were also ordained, and it was the first ordination by Late Bishop Urban McGarry. They were Late Fr. Mathew Chennatt and Thomas Vetticad.

When the TOR’s took over Poreyahat Parish from the Jesuits in 1940, there had been already 871 baptisms on record. When Bhagalpur became a Prefecture, Poreyahat had already 2464 Catholics. Seven of the Mass Centres of Poreyahat have now become full-fledged parishes with resident Priests.
