The Eparchy of St. Peter the Apostle purchased the building and immediately began renovations to transform it into a suitable place for the Chaldean liturgy.

Additionally, the Eparchy acquired a small house next to the church for administrative purposes, a plot of land for parking, and a larger house connected to the property to serve as a monastery for the monks who assist in serving the parish community.

The Chaldean Church traces its origins back to the apostolic times, with Saint Thomas the Apostle evangelizing the inhabitants of Mesopotamia before his martyrdom in India.

The construction of St. John Chaldean Catholic Church was significantly supported by fundraising efforts led by the Mar Toma Council.

This council, comprising members of the local Chaldean community, organized events and drives that raised the necessary funds.
