Bishop Chulaparambil was an ardent devotee of the most Sacred Heart of Jesus. While studying in Candy Seminary, Sri Lanka, he fostered a strong devotion to the Sacred Heart and a special attraction to the life style of St. Francis De Sales, which was highlighted in his pastoral letter, dated 21st November, 1931.  With a view of founding a religious institute, he invited a few priests interested in religious life from the Archeparchy of Kottayam. On 20th November, 1921, the bishop blessed a little chapel and the first house of the society; and later with the approval of the Holy See, Mar Chulaparambil, raised this association as an institute for priests and lay brothers in the Archeparchy of Kottayam and named it ‘The Oblates of the Sacred Heart (OSH)’.

  

On 29th January, 1924 the first members made their religious profession in the presence of the eparchial bishop.  The first members of the Society of OSH were a group of clerics and brothers of the Archeparchy of Kottayam.  They were gathered together to form a community at Sacred Heart Mount, on the feast of the Presentation of Our Lady on the Temple under the leadership of Fr. Kuriakose Kuzhimullil, the first superior.

 Bishop Chulaparambil, by his Decree dated 29th January, 1930, canonically erected the Society by framing its general rules based on the Rules of St. Charles Borromeo’s Oblates of St. Ambrose. The founder bishop, by erecting the Society of the OSH, envisaged not only the personal sanctification of its members but also their availability for various ministries in the Archeparchy as well as in the Universal Church, such as pastoral, ecumenical, family apostolate, etc. He was called for eternal reward on 08th January, 1951.
