Délia Tétreault (Marie of the Holy Spirit)
Quebec foundress of the Missionary Sisters of the Immaculate Conception
Who they were
Délia Tétreault founded the Missionary Sisters of the Immaculate Conception, the first Canadian missionary congregation of women.
The miracles
No miracle has been approved. The decree on heroic virtues has been promulgated; a miracle would come next.
Why that counted as sanctity
The diocesan inquiry opened in Montréal in 1985 and the decree on her heroic virtues was promulgated on 18 December 1997.
The cause
The cause continues. No postulation address is published here yet. Favours received through this person’s intercession, and offers of help, are best sent to the religious order or congregation they belonged to, or to the diocese where the cause was opened; either will pass them to the postulation.
