The origin of the mission at New Rajnagar, Ghaziabad goes back to the Vincentian athers from Kerala. They started an English Medium School in New Rajnagar, Ghaziabad. At the untimely death of Fr. Emmanuel Pallikunnen V.C. who was managing the school, the Vincentian Fathers, left for Kerala and the school was taken over and run by Amadeus OFM Cap.of the Province of Tuscany, the parish priest of Sacred Heart Church, G.T. Road, Ghaziabad. He renamed De Paul School as St. Paulís Academy. At his request the Indian Capuchins took over the school in 1978. Br Mathew Ullat was assigned to New Rajnagar to manage the school. Br. Hadrian joined Br. Mathew and they stayed in a rented building which was used also as the school. The Holy Cross Sisters from Piplera helped out in the school. In 1981 the Holy Cross Sisters were replaced by the F.C.C. Sisters.

In the meantime a new plot of land was acquired and the building work of the school started in all earnest. By January 1983, the school was shifted to the new premises. At one corner of the compound a convent was built for the sisters by Br. Mathew Ullatt. The faithful around the area attended Holy mass in a classroom and a parish was established in New Rajnagar under the patronage of St Paul.

In 1991, after ten years of service the F.C.C. Sisters left for good and Frs. Ivan and Simon Kottoor so far living in their school offices shifted to the convent building and it became their residence. St. Paulís building was completed and was raised as a Senior Secondary School under Bros. Simon & Ivan.

In 1992, Fr. Ivan built the Parish Church with Special permission from the G.D.A. and Fr. Hugh furnished it. The inauguration and blessing of the Church took place on 20 December 1992 by Bishop Rt. Rev. Patrick Nair. Foundation Stone for the K.G. Block was laid by Fr. Dominic Thirunilath, the Vice-Provincial in 2006 and the constrction works were supervised by Brs. Alexander and Simon. Bros. Skylark George and Freddie are appointed as guardian and principal, parish, and manager respectively.
