[2] Pretorius's doctoral work encompasses the interaction between science and theology, including integrating evolution and the creative acts of God found in Genesis 1-2.
[3] He has written several published articles on this relationship (amongst others), in the academic journals Verbum et Ecclesia, HTS Theological Studies,[4] and Conspectus.
The concept of cymatics, on which the model is based, is a well-examined and published idea, especially in view of the work of Robert Hooke (1680), Ernst Chladni (1787), Hans Jenny (1967), and currently by John Stuart Reid.
[6] In the last several years, Pretorius's research has moved towards studying spiritual consciousness and experiences, as attested by his recently published articles.
Examples include ISTL (International Seminary of Theology and Leadership) in Switzerland, FIET (Facultad Internacional de Educación Teológica) in Argentina and EFGBC (Ethiopian Full Gospel Believers Church) in Ethiopia.
