The search for a good method to analyse sermon content (and the content of interview documents) has been prevailing since the past decades to evaluate current practice so as to construct better theories for practice. I think that we have found it in the methodology of inductive, qualitative research of the Grounded Theory methodology. In this article, I am going to use the Grounded Theory approach to describe the phases of qualitative empirical research, namely, literature study, sampling, open coding of the data, selective coding of additional new data and theoretical coding to be able to construct an emerging theory of praxis using the concepts developed for this specific action in our discipline. There are critical comments for this methodology. I will try to address these critical views and argue that the Grounded Theory is in line with the science of research.
