" SHORT ECCLESIASTICAL HISTORY "
The first Vicariate Apostolic of Bengal was established in year 1834, with its headquarters at Kolkata. Fr. Zubiburu, a Spanish Carmelite priest was the first missionary went to Koikhali in the year 1840 along with Mr. Crow, the District Magistrate . They built a catholic community of 278 members during the time of Msgr Patrick Carew who was Vicar Apostolic. At present Koikhali comes under Raghabpur parish. Owing to bad health he could not continue his work and left the place.

In the year 1859, the Belgian Jesuit missionaries came to Bengal. In 1868 at the invitation of Kala Chand ( Stanislas), Father Goffinet SJ went to a small village called Gokurni near Magra Hat. A few days later in July 1868, he baptized a little girl of six in Magra Hat which was the happy passage for the Christian community in 24 Parganas. From here again Father Goffinet SJ went to Koikhali and continued the missionary work started by the Spanish Carmelite priest, under Msgr. Steins SJ. Father Goffinet SJ lived a saintly life. Later it was Father E. Delplace SJ the pioneer who went around establishing five mission stations in four years, Raghabpur, Morapai, Basanti, Khari and Baidyapur. (1873-1877). In 1877 Msgr. P. Goethals became the Vicar Apostolic. During this time because of the expansion of the Chotanagpur mission, three Missions were closed and only two were retained, namely Morapai and Raghabpur.

In 1886 the Vicariate Apostolic became the Archdiocese of Calcutta. Under the guidance of Archbishops P. Goethals and B. Meuleman SJ the Chota Nagpur Mission developed wonderfully, so much so, that in 1927 Ranchi became an independent diocese. Archbishop Perier SJ was at the helm from 1924 to 1960. During this time more attention was given to the Bengal Districts. The Yugoslav Jesuit Priests were invited to come to Bengal and to take charge of the 24 Parganas District. That move marked a new start of the Sunderbans' Mission. Starting from 1925 right up to 1950, 18 Jesuits came from Yugoslavia to work in the Bengal Mission; most of them were posted in the 24 Parganas. They started new mission stations or re-opened old ones, they built churches and chapels and generally, they injected new life in the existing Catholic communities. After the war, unfortunately, the doors were closed and no new missionaries could come in. Later the Belgian Jesuits and Indian priests took over the missions. The tenure of Archbishop V. Dyer (1960-1962) and Archbishop Albert D'Souza (1962-1969) witnessed further divisions of the Archdiocese, the dioceses of Jamshedpur, Darjeeling and Dumka were established. Father L.T. Picachy SJ became the Bishop of Jamshedpur and later Archbishop of Calcutta in 1969 and Cardinal in 1976. In 1978 the Diocese of Baruipur was born.
