Overview
Saint Mbaaga's Major Seminary Ggaba is a Catholic diocesan seminary and house of formation in Ggaba, a neighborhood of Kampala's Makindye Division, approximately 10 kilometres southeast of Kampala's central business district. It is owned and administered by the Roman Catholic Archdiocese of Kampala and operates under the broader auspices of the Uganda Episcopal Conference. The institution's principal role is to prepare men who pursue the priesthood later in life, commonly described as late vocations, through academic, pastoral, spiritual and community formation. The institution occupies premises with a longer history in Catholic education and priestly training. The buildings were opened in 1931 by the Mill Hill Fathers as Mill Hill Major Seminary Ggaba. That institution operated for 36 years before closing in 1967. From 1967 to 1975, the site hosted the Pastoral Institute of Eastern Africa. The institute later moved to Eldoret, Kenya, in the context of Uganda's difficult political and security environment during that period. The current seminary began operating on the site on 16 February 1976, following the initiative of Cardinal Emmanuel Kiwanuka Nsubuga, then Archbishop of Kampala. Its original purpose was to provide a formation pathway for late vocations in the Kampala Archdiocese. Twelve seminarians joined on the official opening day, and four more entered in May of the same year, bringing the first intake to 16. Over time, the seminary expanded its service beyond Kampala and received candidates from other Ugandan dioceses, including Kiyinda-Mityana, Kasana-Luweero, Lugazi, Masaka, Jinja, Fort Portal, Hoima and Lira. Its academic programme covers philosophy and theology. Successful students receive a Diploma in Philosophy and a Diploma in Theology. The seminary combines classroom education with pastoral work and the wider formation expected of Catholic clergy. In the 2017/2018 academic year, the institution reportedly enrolled 200 seminarians, including 21 engaged in pastoral work. It has been described as the only diocesan major seminary in the Association of Member Episcopal Conferences in Eastern Africa region, giving it a role that extends beyond the immediate boundaries of the Kampala Archdiocese. The seminary remains an active Ugandan Catholic formation institution. It marked its 47th year in 2023 and held its 38th graduation ceremony on 25 May 2023, when 44 graduands completed their programmes. In 2024, it reported 51 graduates while commemorating 48 years since the current seminary was established. Its alumni from the earlier Mill Hill period include senior Catholic prelates such as Cardinal Maurice Michael Otunga, James Odongo, Joseph Mukwaya, Erasmus Desiderius Wandera, Joseph Oyanga, Denis Kiwanuka Lote and Philip Sulumeti.
History
The site now occupied by Saint Mbaaga's Major Seminary Ggaba has been associated with Catholic education and clerical formation since the early twentieth century. The premises were built and opened in 1931 by the Mill Hill Fathers as Mill Hill Major Seminary Ggaba. That seminary operated for 36 years and closed in 1967. A different educational institution, the Pastoral Institute of Eastern Africa, then used the premises from 1967 until 1975. The institute relocated to Eldoret, Kenya, after operating conditions in Uganda became difficult because of the political and security environment. The present seminary was established on the same premises on 16 February 1976 at the direction of Cardinal Emmanuel Kiwanuka Nsubuga, Archbishop of Kampala. It was created to serve candidates who entered the priestly vocation later in life and therefore required a dedicated diocesan formation route. The initial intake consisted of 16 seminarians: 12 joined by the formal opening in February and four more entered in May. Although founded for the Kampala Archdiocese, the institution subsequently accepted seminarians from other Ugandan dioceses, including Kiyinda-Mityana, Kasana-Luweero, Lugazi, Masaka, Jinja, Fort Portal, Hoima and Lira. Saint Mbaaga's provides academic and pastoral formation rather than general commercial education. Its curriculum includes philosophy and theology, with successful students receiving diplomas in both fields. The academic programme is integrated with pastoral work and the spiritual and communal disciplines associated with preparation for Catholic ministry. In the 2017/2018 academic year, the seminary was reported to have 200 seminarians, of whom 21 were undertaking pastoral work. The institution has also been characterized as the only diocesan major seminary in the Association of Member Episcopal Conferences in Eastern Africa region, reflecting its regional significance within Catholic formation networks. The institution's historical importance is also reflected in the careers of clergy educated during the Mill Hill period. Listed alumni include Cardinal Maurice Michael Otunga, former Archbishop of Nairobi; James Odongo, former Archbishop of Tororo; Joseph Mukwaya, former Bishop of Kiyinda-Mityana; Erasmus Desiderius Wandera, former Bishop of Soroti; Joseph Oyanga, former Bishop of Lira; Denis Kiwanuka Lote, former Archbishop of Tororo; and Philip Sulumeti, former Bishop of Kakamega. The current seminary has continued to mark its institutional development through graduation ceremonies. Its 38th graduation ceremony took place on 25 May 2023 and included 44 graduands, alongside recognition of the institution's 47th year. In 2024, 51 students graduated as the seminary marked 48 years since its 1976 foundation. As of May 2024, Reverend Father Joseph Sserunjoji served as rector and Reverend Father Ambrose Bwangatto as academic dean.
