Crookston, Minnesota – The Sister Annella Guild is pleased to announce the opening of the cause for the canonization of Sister Annella Zervas, OSB. A professed Benedictine of Saint Benedict’s Monastery in St. Joseph, Minnesota, Sister Annella died in 1926 at the age of 26 after a life marked by profound faith, virtue, and patient endurance of great physical suffering. Her witness to Christ continues to inspire the faithful today. Bishop Andrew H. Cozzens, S.T.D., D.D., formally announced the opening of the cause today, August 20, 2025, in an official video statement, which can be viewed here: Watch the announcement.
After completing the necessary preliminary investigation, Bishop Andrew Cozzens, bishop of Crookston, has received a nihil obstat from the Holy See, indicating that there is no objection to formally opening the diocesan phase of the cause. This phase will include:
● Collection of testimonies regarding Sister Annella’s life, virtues, and reputation for sanctity.
● Consideration of any reported favors attributed to her intercession.
● The establishment of a historical commission in accordance with the norms of Canon Law.
The Mass will be celebrated in person and via livestream on Thursday, October 9, 2025, at 6:30 PM CDT at the Cathedral of the Immaculate Conception in Crookston, Minnesota. Doors open at 4:00 PM for an exhibit on the life of Sister Annella. At 5:00 PM, Patrick Norton will share his story, followed by an organ recital at 6:00 PM, and the Opening Mass at 6:30 p.m. Food will be available for purchase.
The faithful of the diocese and beyond are invited to participate in the cause by:
● Offering prayers for the progress of the cause.

The opening of Sister Annella’s cause reflects the Church’s careful discernment and the enduring devotion that has remained strong since her death nearly a century ago. Her example of surrender to God’s will, patient endurance of suffering, and love for the Holy Eucharist serves as a model for Christian life today.
