History of the Diocese of Hosur
The Syro Malabar Diocese of Hosur was erected on 9th October 2017 and was officially inaugurated on 22nd November, 2017, together with the consecration of its first Bishop Mar Sebastian Pozholiparambil. Geographically the diocese is extended to nine districts of northern Tamil Nadu - Dharmapuri, Krishnagiri, Thiruvannamalai, Vellore, Kadalore, Vizhupuram, Kanchipuram, Thiruvalloor, and Chennai, and union territory of Pondicherry-Karackal.
The Syro Malabar mission in Chennai has begun in December 13th, 1983, at the invitation of the then Archbishop Most Rev. Dr. R. Arulappa. Rev. Fr. Jose Palatty, a zealous priest from the diocese of Irinjalakuda, Kerala, was appointed as the first chaplain of the Syro Malabar faithful. The pastoral care of the Syro Malabar faithful in Chennai was entrusted to the Syro Malabar diocese of Irinjalakuda, under its Lordship Mar James Pazhayattil. In the beginning the area was limited to Archdiocese of Madras-Mylapore. When the diocese of Chigleput was erected, the area is extended to that diocese also. Begun with one priest, slowly number of priests increased and they organized the Scattered people into communities. The community began to construct their own prayer halls for their spiritual needs. In 1990s different congregations, both men and women, came for mission work and they began education institutions, social work Centres and hospitality Centres.
In 2005, November 5th Most Rev. Dr. A. M. ChinnappaS D B has raised our prayer halls into public worship centres and priests there as their rectors. When the Mission celebrated its Silver Jubilee in 2008, on 21st December Most Rev. Dr. A. M.Chinnappa, S D B declared ten personal parishes, juridically covering the whole Archdiocese. St. Thomas Pastoral Centre at Ayanavaram, Chennai became the co-ordination Centre, and its head became the Co-Ordinator for Syro Malabar faithful in Chennai-Chigleput.
On 9thMarch, 2005, the then Archbishop of Pondicherry-Kadalore, Most Rev. Dr. Antony Anandarayar, erected a personal parish for Syro Malabar faithful living in the Pondicherry vicariate. Rev. Fr. Sebastian Chittilappilly C M I was appointed as the first parish priest.
In 2010 when Mar James Pazhayattil retired from the see, Mar PaulyKannookadan was consecrated as the new Bishop of Irinjalakuda, who, following the steps of his predecessor, ardently worked for the Chennai Mission especially to realize it a Diocese.

At present there are 25 parishes in the diocese covering the whole faithful. 25 diocesan priests, 17 religious priests and 119 Religious Sistersare engaged in the pastoral ministry of the diocese.
