Given the interdisciplinary nature of our study, we have first limited ourselves to the sociological Praxeology of KAMBAJI WA KAMBAJI, Kambajism, to which we have associated the theoretical and methodological bases borrowed from Biblical Exegesis, theological hermeneutics, kerygmatic homiletics and the pragmatics of religious knowledge, knowing that it is the nature of the object of study and the objectives of the researcher that determine the choice of the research method to use in a particular sociology. It was necessary for us, in the name of interdisciplinarity, to flesh out our methodological approach by extending Kambajian Praxeology to the discourse of theo-gnoséological power by relying on the two batteries of heuristic prerequisites so that each tendency would not be irritated but would usefully find its part in our analyses. This procedure has allowed us to arrive at the "Interdiscursive Theo-functional Praxeology" and to move towards the "Praxeological Sociology of Gnoseological Pragmatism" by incorporating the key axioms and principles of the Pragmatics of Communication.
