In 1984 to meet the spiritual requirements of Syro Malabar Catholics in and around North Bangalore, mainly Yesvanthpur, Mathikere and Jalahalli areas, St Thomas Catholic Association Jalahalli was formed under the leadership of the Claretian Missionaries.

On 17th February 1985, His Excellency Mar Jacob Thoomkuzhy, the then Bishop of the Diocese of Mananthavady blessed the new chapel and Rev Fr. Mathew Keechira, CMF was appointed as the priest-in-charge. On 1st March 1989, St Thomas Church, Jalahalli was raised to the status of a full-fledged parish under the jurisdiction of Bangalore Archbishop, by His Grace Most Rev Dr Alphonse Mathias, the then Archbishop of Bangalore. The parish has since grown tremendously and is today a community with more than 2700 members under the Diocese of Mandya.

On 7th November 2021, the parish was elevated to the status of a Forane Church based on a request by the Parish Priest and the entire body of the faithful.
