Professor Kalu was one of the most influential Nigerian scholars.

From the early 1970s until his death in 2009, he provided leadership in theological education in Africa and expanded the boundaries of Church History. A prolific writer on a wide range of subjects, Kalu has authored or edited more than sixteen published books including Divided People of God: Church Union Movement in Nigeria (New York, 1978); The History of Christianity in West Africa (London: Longman, 1980); African Church Historiography: An Ecumenical Perspective (Berne, 1988); Embattled Gods: Christianization of Igboland (Lagos/London, 1996); Power, Poverty and Prayer: The Challenges of Poverty and Pluralism in African Christianity (Frankfurt, 2000); African Christianity: An African Story (University of Pretoria Press, 2005), African Pentecostalism (2008); Clio In A Sacred Garb: Christian Presence and African Responses, 1900-2000 (2008); and over 180 articles in journals and as book chapters. One of his latest books was African Pentecostalism: An Introduction, published by Oxford University Press in 2008, which is already regarded by many as the authoritative work on the subject.
He served his field as a member of the editorial board of over fifteen academic journals including Journal of Religion in Africa; Mbari: The International Journal of Igbo Studies; Ikenga; African Theological Journal among others. He was also editor of West African Religion (1975-1987), Religion (1977-1980), and Nigerian Journal of Social Studies (1979-1982).
He also served Christianity in many ways. He was the secretary general of African Theological Institutions (Nairobi, Kenya) from 1970-1981; chairman, Conference of African Theological Institutions (Nairobi, Kenya). Until his death, he was secretary and coordinator, Associations of African Church Historians and member of the Governing Council, Spiritan School of Theology, Enugu, Nigeria. He was also a member of the Executive Board of Currents in World Christianity, University of Cambridge and chair of the Executive Board section on Evangelism and Globalism in 1998.
Ogbu Kalu was respected internationally not only for his scholarship but for his church leadership. He was a man of deep Christian faith and conviction and served as an elder in the Presbyterian Church of Nigeria. But the most important thing to him had always been the family.  Those who knew him on a professional and personal level will miss him dearly.

I first met Professor Ogbu Kalu in 1997 when I was a graduate student at the University of Toronto. He was at the University of Toronto on a sabbatical leave. In those 11 years, Professor Ogbu Kalu remained one of the greatest inspirations in my life, a mentor, and a friend. I was frequently invited by Professor Ogbu and his wife to their temporary home in Toronto during his sabbatical at Toronto. I looked forward to those visits and my occasional task of barbing his hair. Even though sometimes I did not do a good job as a barber, he was always gracious with his praise for my skills as a barber. I came to love him as a human being but most importantly as someone who genuinely loved and cared about other people.
My last conversation with him before Christmas he said: “Chima, congratulations of your new book. This has been a very productive year, but I hope you also have time for the family and doing your job in that angle.”
