The congregation of the Sisters of the Adoration of the Blessed Sacrament (SABS) which was founded on 8th December 1908 at Champakulam in the Archdiocese of Changanacherry, Kerala, India has its origin from the deep personal experience of the Eucharistic presence of the Venerable Mar Thomas Kurialacherry (1873-1925), an ardent devotee of the Holy Eucharist.
