The Canadian missionary Bernar Lonergan (1904-1984) published his significant work "Insight: A Study of Human Understanding" in 1957. Throughout his nearly thousand pages, he proposes a rigorous epistemological path to understand this very understanding itself, especially the moment when something is revealed to us and clarity is achieved.

Mastering the ideas of this brilliant work, Lonergan later developed a "method" to "reach understanding" in the field of theology. He approaches this field interdisciplinarily, as theology is not an isolated science but connected to other human knowledge, particularly social sciences.

For this encyclopedic thinker, "the method is not a set of rules that someone must follow, even the most foolish. Instead, it is a framework designed to enhance creativity and collaboration. The method describes the various groups of functions that theologians must perform in order to fulfill their duties [...]. In modern theology, we consider eight different tasks: research, interpretation, history, dialectic, explanation of foundations, establishment of doctrines, systematization, communication" (Introduction).

Ultimately, the proposed "theological method" aims to help those approaching theology to discover its own dynamic structure, which assists them in gaining knowledge and verifying its validity, always within a genuinely creative framework.
