The beginning of the ALCP/OSS in Africa Province was in 1970’s when the first seminarians met the founder, late Very Rev. Fr. Bernhard Bendel. The centre for the meetings was at RAUYA, the centre for the Holy Spirit Sisters (ALCS/OSS). The home for this new Society in the Opus Spiritus Sancti was not yet, thus all the meetings, short formation programmes for those who joined this new Society were carried out at Rauya in the Catholic Diocese of Moshi.
Apart from meeting the founder, the candidates met also with late Bishop Joseph Kilasara who by then as the Bishop of the Catholic Diocese of Moshi welcomed/invited the founder in the Diocese. Late Bishop Joseph Kilasara remained to be the formator of the candidates for the ALCP/OSS till his death at Rauya in 1978. The first seminarians were Ezekiel C. Kanje, Thadei Mworia and Henry T. Mushi. Later, they were joined by others including Raphael Kigunga.
The HOME of this young Society in the Opus Spiritus Sancti emerged into light on the 27th February 1980 when a group of eighteen (18) candidates and three Priests moved into their house at Sabuko, Sanya Juu-Moshi, Tanzania.   From there, Sabuko grew and flourish in getting vocations and the house was slowly taking shape the buildings and the surroundings. The centre was the place of all the activities of the ALCP/OSS at that time:
Now Sabuko is Mother House for the ALCP/OSS  Society, the Africa Provintialate Office and the centre for the first year formation (Sabuko Formation House).
