According to a 1989 newspaper article: By 1927, there were a few reports of people who had been cured of illnesses through [Zervas's] intercession. By 1929, the
St. Paul Daily News reported, "There have been hundreds of cures effected, thousands seek relief at her grave, and thousands write for information about her life." By 1930, several women were requesting that their sick children sleep in her deathbed in hopes of a cure. In 1932, a woman claimed that she had taken a vine from her grave, put it in water, used the water in a bath, and was relieved of a painful backache. By the 1940s, there was a rumor that the grass on her grave stays green year-round because she was so holy.Within seven months of her burial, Bishop
Joseph Busch was hearing rumors of cures and favors granted by Zervas's
intercession. He asked Bendictine priest Alexius Hoffmann of St. John's Abbey to collect information on "the circumstances of her sickness and death and the origin and progress of the
cultus, if any, in her regard and any evidences there may be of miraculous intervention through her intercession". In 1957, James Kritzeck wrote, "Whatever may happen, everyone can pray to her and have confidence in her intercession." According to a 1989 article for the
Visitor, the official newspaper of the
Roman Catholic Diocese of Saint Cloud: "While the
St. Paul Daily News exaggerated when it reported that 'thousands' were visiting her grave, there were some pilgrims to the convent cemetery, and many of them took a handful of dirt from Sister Annella's grave for a souvenir. Interest in Sister Annella dwindled during the 1960s, but she still has some fans. At least one of them, no one seems to know who, puts flowers on her grave regularly." According to journalist Vicki Ikeogu, local indifference to Sister Annella persisted until 2008, when St. Cloud-based
freelance writer and
historian Brendan D. King learned of her while volunteering in the Archive Room of the Stearns County Historical Society and began researching. According to Ikeogu, "Combing through archives within the monastery, King would uncover what he described as a compelling story on suffering and devotion to God. It was a story he published in December 2008 in the
Catholic Family News." When asked by Ikeogu why he thought interest in Sister Annella had disappeared in the 1960s, King cited the rapid
cultural secularization of once overwhelmingly Catholic Central Minnesota after the
Second Vatican Council, but added, "Sister Annella’s viewpoint on spirituality, the fact that suffering was not a curse, I think may have made a lot of people see her as strange. But I think God raises up saints for a reason and he also makes them known to us for a reason."
Formal cause for canonization A spokesperson for Bishop
Donald Joseph Kettler of the Diocese of St. Cloud announced that as of 2017, a cause for the canonization of Zervas had not been opened, nor was its opening anticipated. While the Benedictine sisters complied before the 1960s with requests for relics, pamphlets in multiple languages, and memorial cards, the convent has since embraced a policy discouraging efforts to promote the canonization of its deceased sisters. According to Sister Karen Rose, while the Benedictine Sisters do not oppose canonizations, "Under the Rule of St. Benedict, humility is a very central concept... The idea of promoting one of our own is really kind of alien to us." On October 15, 2023, Bishop
Andrew Cozzens of the
Diocese of Crookston announced that preliminary steps were being taken to formally open Zervas's cause for canonization. The diocese has a website about Zervas and is forming a nonprofit
guild encouraging devotion to her. In a letter, Cozzens thanked Norton for almost single-handedly reviving interest in Zervas. On November 12, 2024, the
US bishops voted to approve the cause's diocesan phase. The formal opening of the cause is scheduled for October 9, 2025, after Mass is celebrated at the
Cathedral in Crookston. ==Folklore==
