In his first major leadership appointment within the Roman Curia, Pope Leo XIV has selected Sr. Tiziana Merletti, a canon lawyer and member of the Franciscan Sisters of the Poor, to serve as secretary of the Dicastery for Institutes of Consecrated Life and Societies of Apostolic Life. This appointment marks a significant step in the new Pope’s efforts to shape the Vatican’s administrative structure early in his papacy.
Sr. Merletti will be taking over the position from Consolata Missionary Sr. Simona Brambilla. Earlier this year, in January, Pope Francis had named Brambilla as the prefect of the dicastery, making her the first woman ever to lead a Vatican dicastery. With Merletti now stepping into the role of secretary, another woman is taking a top-level role within the same department, reflecting a growing presence of women in leadership positions within the Vatican.
The announcement of Merletti’s appointment was made public by the Vatican on May 22. Following the news, the International Union of Superiors General (UISG) expressed its appreciation for Pope Leo XIV’s decision and extended warm congratulations to Merletti. The UISG, which represents superiors general of women’s religious orders around the world, highlighted her significant contributions to the Church through her expertise in canon law and her work in safeguarding.
“As a member of the union’s canon law council and a member of the Commission for Safeguarding operated jointly by the men’s and women’s unions of superiors, her contributions are a gift to our global network, promoting justice, care and integrity in consecrated life,” the UISG said in a statement. “We congratulate Sr. Tiziana on this important mission and assure her of our prayers as she takes on this new responsibility in service to consecrated life around the world.”
The Dicastery for Institutes of Consecrated Life and Societies of Apostolic Life plays a vital role in the governance and guidance of religious life within the Catholic Church. According to the apostolic constitution that outlines the structure and responsibilities of the Roman Curia, this dicastery is “called to promote, encourage and regulate the practice of the evangelical counsels, how they are lived out in the approved forms of consecrated life and all matters concerning the life and activity of Societies of Apostolic Life throughout the Latin Church.”
This means the dicastery oversees matters related to the spiritual and organizational well-being of religious communities, including women and men who have dedicated their lives to the Church through vows of poverty, chastity, and obedience. Its jurisdiction includes religious sisters, brothers, and priests who live in community, as well as those who serve in apostolic ministries across the globe.
The scale of religious life in the Catholic Church is substantial. Based on the latest Vatican statistics, there are nearly 600,000 women who have professed religious vows. In addition, there are about 128,500 priests belonging to religious orders and roughly 50,000 religious brothers. These individuals form the foundation of numerous ministries in education, healthcare, social services, and evangelization efforts around the world.
Sr. Tiziana Merletti brings with her decades of experience in both leadership and scholarship. She was born in the town of Pineto, Italy, and is currently 65 years old. Before entering religious life, she completed a degree in civil law, demonstrating early on her aptitude for rigorous academic study and legal reasoning.
She took her first vows as a member of the Franciscan Sisters of the Poor in 1986. This religious congregation is known for its dedication to serving the most vulnerable members of society, inspired by the values of St. Francis of Assisi. Following her profession of vows, Merletti pursued further academic study, and in 1992 she earned a doctorate in canon law from the Pontifical Lateran University in Rome.
From 2004 to 2013, she served as the superior general of the Franciscan Sisters of the Poor, a role that gave her deep insight into the challenges and hopes of religious life in the modern world. During her tenure, she provided guidance to members of the congregation across various countries and contexts, further deepening her understanding of global religious communities.
At the time of her recent appointment, Merletti was based in Rome where she had been teaching canon law at the Pontifical Antonianum University. In addition to her academic responsibilities, she served as a canon law expert with the UISG, lending her expertise to discussions and decisions affecting religious orders around the world. Her dual role as a teacher and advisor positioned her as a respected figure within the international community of religious women.
Her appointment by Pope Leo XIV reflects the continuation of a broader trend initiated under Pope Francis: the increasing inclusion of women in positions of leadership within the Catholic Church. Although the Church continues to reserve ordained ministry to men, it has expanded opportunities for women to take up important roles in governance and administration.
The choice of Merletti, with her extensive background in both law and leadership, suggests a papacy that intends to maintain and build upon the foundations laid by its predecessor. Pope Leo XIV appears committed to fostering a Curia that is reflective of the broader Church, valuing competence and service over hierarchy alone.
As Sr. Merletti assumes her new position, she will be tasked with supporting the prefect in overseeing the vitality and regulation of consecrated life worldwide. Her legal expertise will be particularly important in evaluating new religious communities, addressing internal governance issues, and helping religious orders navigate the complex intersection of Church law and modern social realities.
The UISG’s statement of support underscores the confidence the global community of religious women has in Merletti’s ability to lead. “We congratulate Sr. Tiziana on this important mission and assure her of our prayers,” they said, expressing not only encouragement but also the hope that she will bring a spirit of compassion, justice, and fidelity to her new role.
Sr. Tiziana Merletti’s journey—from a law student in Italy to a top Vatican official—exemplifies the possibilities of religious service in today’s Church. Her blend of academic discipline, spiritual commitment, and global awareness uniquely equips her to guide the dicastery in fulfilling its mission to support and nurture consecrated life across the Catholic world.
