July 13 1979, Mother Marie-Rose was declared Venerable

During the General Chapter of 1926, the Congregation of the Sisters of the Holy Names of Jesus and Mary decided to introduce the Cause of Mother Marie-Rose, foundress of the community. The diocesan process, begun in Montreal in 1927, was followed by an exhaustive research based on the documents concerning the life and works of Mother Marie-Rose. This task was confided to Mother Marie-Ludger, SNJM General Secretary and Archivist at the time. The synthesis of this research (the Positio) was drafted by Father Conrad-M. Morin, omi, and Sister M. Louise-Émilie, snjm.

Following this study, Pope Paul VI accepted the Cause of Mother Marie-Rose in 1972, and on July 13, 1979, Pope John Paul II decreed that Mother Marie-Rose lived in a heroic way the theological virtues of faith, hope and charity toward God and neighbor as well as the virtues of prudence, justice, temperance and fortitude.
Subsequently, the process including petitions and recognition of miracles led to the beatification of Mother Marie-Rose. On May 23, 1982, Pope Paul II declared Marie-Rose Durocher blessed.
