What will become the Boma Evangelical Graduate School of Theology opened its doors in 1976 as the Boma Seminary. In fact, the idea of a graduate school of theology for the Evangelical Community of the Alliance in Congo was first suggested in the sixties by the late Willys Braun, a missionary with the C&MA in Congo who was then serving as the Director of the Kinkonzi Bible Institute. Dr. Braun went so far as to build a building that was to house the planned school of theology.

Dr. Braun's idea was revived 15 years later at the Kinkonzi Bible Institute, which was then under the leadership of Rév. Jean-Pierre Mayunda-ma-Tsumbu Nzelele. Convinced that the idea of graduate school of theology is one whose time has come, Dr. Joël Kuvuna-ku-Konde Mwela, who was then serving as the national President of the Evangelical Community of the Alliance in Congo, conveyed a meeting of representatives of the Kinkonzi Bible Institute, the Christian and Missionary Alliance, and the ECP/CEAC to study its feasibility. With the help of the Christianity and Missionary Alliance in the USA and Canada, the Evangelical Community of the Alliance in Congo launched the Boma Seminary in September 1976.

Three students were part of the first class: Esaron Lelo Mavinga, Dynobert Nlandu Nguala and Justin-Abraham Kumbu-ki-Makaya.

With a teaching faculty of three full-time professors, Raymur Downey, Lammert Hukema, and Britta Hukema, and one visiting professor, Nathalis Songo Vangu, who became full time professor the following year, what was then known as Institut Supérieur Théologie Évangélique de Boma (ISTEB) began to offer pastoral training leading to an undergraduate degree. The arrival of Dr. Flyod Shank in 1979 gave a new impetus the seminary's academic programs, establishing in the process a trend that will continue with the arrival of new professors, such as Arie Verduijn (1981), K. Bruce Edwards (1983), Esaron Lelo Mavinga (Janvier 1986), Mabiala Justin-Robert Kenzo (Octobre 1986), Louis Matundu Zulu (1986), Philippe Manzali Tsisi (1986), Claude Lendo Luyindula (1990), César Mata Ndudi (1991), Lydie Kwangu Seke (1991), Joseph Ngoma Nzita (1992), Véronique Mabiala Dikoba Ngoma (1992), Jérémie Khele Tsatu (1994), Nzuzi Mbenza (2000), Anastasie Masanga Mampoda (2004), and Gabriel Tsumbu Mayunda (2005).

The seminary has also greatly benefited from its roster of part-time and visiting professors among whom we may name Joachim Maduka Nzau, Joseph Mavinga Nzita, Timothée Taty Tshika, Justin Mayenda Ma Mbongo, Kitikila Dimonika, Nymi Panzu, Chris Braun, Ron Brown, etc.

Under the leadership of Dr. Nathalis Songo Vangu, its first African Rector, the seminary underwent a significant growth sprout. Unfortunately, this growth would come to a virtual halt with the turmoil in the Congo during the nineties. Yet, it is also during this time that the seminary changed its status from a seminary to graduate school, offering both undergraduate and graduate degrees. This explains the change in the name of the institution, from Institut Supérieur de Théologie Évangélique de Boma (ISTEB) to Faculté de Théologie Évangélique de Boma (FACTEB).
