A.S. (Albert) Geyser was professor of New Testament at the University of Pretoria from 1946
to 1961, when he accepted an appointment at the University of the Witwatersrand. He was one
of the most active and outspoken critics of apartheid and played a leading role in the
establishment of the Christian Institute and the appointment of Beyers Naude as the first
director of the Institute. However, Geyser received very little attention either in church history
or in the history of South Africa. This contribution, presented as the Third A.S. Geyser
Commemorative Lecture at the University of Pretoria, reflects on Geyser’s ecclesiology. It is
quite remarkable that Geyser chose ecclesiology as point of entry into the discourse on
apartheid. He engaged in fundamental theological criticism of segregation in church and state
based on his understanding of the unity of the church in Christ and a humanity unified under
the kingship of Christ.
This was delivered during the third A.S. Geyser Commemorative Lecture by the author on 30 March 2017 at the University of
Pretoria as part of the centenary celebrations of the Faculty of Theology.
