Mar Kuriakose Kunnacherry (1928-2017): 

In founding the Caritas Secular Institute Bishop Thomas Tharayil used to consult Rev.Fr. Kuriakose  Kunnacherry, at that time doing his Doctorate in Canon Law in Rome, and he considerably  helped the Bishop to concretely articulate and work out the canonical requirements of erecting a Secular Institute.

On May 8,1965 Rev.Fr. Kuriakose  Kunnacherry was appointed by the Bishop as the spiritual Director of Caritas Secular Institue.  From that time onwards as well as during his episcopate, Bishop Kuriakose Kunnacherry used to give regular spiritual instructions and guidance to the members. He also took great interest in sending the members for higher training in various disciplines and was instrumental in the overall growth and apostolic expansion of the Institute especially to Germany. During his time the Institute made great strides in the apostolate of the service of the sick, social apostolate, parish apostolate, family apostolate etc.

In the year 1986 the revised  Constitution and Rules  of  the Caritas Diocesan Secular Institute for Women was approved by Bishp  Kuriakose Kunnacherry.(Decree No.17B/86)
