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. He has written several published articles on this relationship, in the Academic JournalsVerbum et Ecclesia,HTS Theological Studies, and Conspectus. The core of Pretorius's research is a study of sound, specifically cymatics, which he assimilates into his studies of Genesis, and commonly refers to it as a cymatic theology. This model, which postulates that creation was initiated by sound, was initially developed in a paper he presented at an academic meeting in Pretoria in August 2008. 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, Ernst Chladni, Hans Jenny, and currently by John Stuart Reid. In the last several years, Pretorius's research has moved towards studying spiritual consciousness and experiences, as attested by his recently published articles.
Readers
A significant part of Pretorius’s academic work, was researching and compiling a wide variety of academic readers for theological students. These readers are used by students in various institutions around the world, who are in partnership with the South AfricanTheological Seminary. Examples include ISTL in Switzerland, FIET in Argentina and EFGBC in Ethiopia. Pretorius was able to research and assemble this material through the Seminary being a member of DALRO. The work has enabled many disadvantaged students over the years to graduate through their various institutions. Pretorius was also a contributor to the book “Academic Writing and Theological Research: A Guide for Students”, which is now the standard book recommended by many academic institutions for use by their students.
