A new study has found that “reciting the rosary privately” is the most popular Marian devotion among those discerning a religious vocation.

The Center for Applied Research in the Apostolate (CARA) at Georgetown University published its June 2025 report: “Impact of Mary, Mother of the Church, on Ecclesial Vocations,” which includes results from six surveys with 1,091 respondents, 65% of whom were diocesan personnel in the U.S. — including bishops (9%), diocesan priests (40%), permanent deacons (10%), and deacon directors (7%).  U.S. religious men and women accounted for the other 35% of respondents including religious priests (6%), major superiors of men (8%), and major superiors of women (21%). The majority of respondents are Latin Rite Catholic (95%), and 5% are Eastern Rite Catholic.
