Pope Leo XIV appoints Sister Mary Teresa Barron as Adjunct Secretary of Dicastery for Evangelization

Catholic IntelligenceUpdated 1 min read

Pope Leo XIV has appointed Sister Mary Teresa Barron as the adjunct secretary of the Dicastery for Evangelization and president of the Pontifical Mission Societies. She is scheduled to begin her new roles on January 4, 2027.

Sister Mary, a member of the Missionary Congregation of Our Lady of Apostles and the current Superior General of that congregation, is the first woman to head the Pontifical Mission Societies. In her dual role, she will also serve as adjunct secretary for the dicastery's Section for First Evangelization and the New Particular Churches.

Sister Mary, who has been a missionary for 34 years, noted that her appointment focuses on animating a missionary spirit rather than academic theological qualifications. Archbishop Kieran O'Reilly, chair of the National Mission Council of the Irish Catholic Bishops' Conference, described the appointment as significant for the Church's missionary outreach. Bishop Niall Coll of Raphoe also welcomed the news, noting that Sister Mary is a native of County Donegal.
