Mother Carla Troenzi, the fourth Superior General of the Comboni Missionary Sisters, assumed leadership at a pivotal moment in the congregation’s history. Her wisdom, missionary experience, and openness to the Spirit’s promptings enabled the Pie Madri to extend their reach across continents, embodying the universality of Comboni’s charism.
Carla Troenzi’s path to leadership was marked by a deep commitment to the missionary vocation. Entering the congregation at age 25, she quickly distinguished herself through her prudence and good judgment. As one of the first sisters to complete nursing training in Rome, Carla’s skills proved invaluable in the missions.
In 1918, when Mother Costanza Caldara opened the first community in Uganda, Sr. Carla was chosen to lead the pioneering group. Her gifts for leadership and her intimate knowledge of the African context made her the natural choice to serve as provincial superior as the Ugandan communities multiplied.
Elected Vicar General in 1931, Carla stood faithfully by Mother Pierina Stoppani’s side. Though unable to dissuade Pierina from her fateful African journey in 1932, Carla’s intuition proved tragically prescient. Pierina’s sudden death on January 3, 1933, thrust Carla into the role of Superior General, a responsibility she shouldered with initial trepidation but growing confidence.
Recognizing the congregation’s need for wise, mission-driven leadership to navigate its rapid expansion, Mother Carla boldly extended the Pie Madri’s presence beyond Central Africa. Under her guidance, new frontiers opened in the Middle East, with foundations in Transjordan and the Arabian Peninsula. Her vision also led the sisters to the Americas, first to minister among African Americans in the United States and later to Brazil.
While some questioned these choices as a departure from the congregation’s founding charism, Mother Carla responded with the insight that Comboni’s own mission had been shaped by obedience to Propaganda Fide. The same spirit of obedience now called the Pie Madri to new lands, in anticipation of the Second Vatican Council’s broadened understanding of mission.
Mother Carla’s legacy includes the launch of Raggio in 1934, the congregation’s first historical source and means of communication among communities and with sisters’ families. Her numerous visits to Africa and the opening of 175 new communities saw the Pie Madri grow to over 2,000 members, with hundreds of novices and an expanding network of novitiates.
After 25 years of selfless service, Mother Carla passed the torch to Teresa Costalunga in 1958. Though archival restrictions prevent a fuller account of her successors’ tenures, the seeds she planted continued to bear fruit, confirming the enduring vitality of Comboni’s missionary vision.
Mother Carla Troenzi’s generalate marks a watershed in the history of the Comboni Sisters.
