The Charism of the Missionary Sisters of Mary Mother of the Church is centred on Jn. 19: 26- 27.
At the foot of the Cross, Jesus gives his Mother to John and John to Mary. John represents the Church and Mary becomes the Mother of the Church.

The Charism of the Institute of the Missionary Sisters of Mary Mother of the Church is a gift of the Holy Spirit to the Founder which is a special share in the Love of Christ for our Lady Mother of the Church. Through this love, the Sister is moulded and manifests the Motherhood of Mary, who leads her towards personal sanctification and missionary activities.

The Founder, who, moved by the Holy Spirit had experienced a deep love of Christ through the intercession of the Blessed Virgin Mary, founded this Institute for women who wish to emulate the Motherhood of Mary..
