The professional and scientific communities understand the methodology of theology in completely different ways; there is no system of common views or unified approaches to theological research. There is a pressing need to develop a methodology for conducting confessional historical or theological research. Answers are needed to the question of what the theological nature of research consists of, since the methodology of theological works is practically identical to research in other general humanities. What is the theological method of research, in particular? Quite a few have been named in recent years. It was said about belonging to a confession, when the confession initially approved the researcher as a person, based on his loyalty. It was assumed that the theological method can consist in research based on the interests of the confession itself, since the interests of the confession itself, aimed at self-preservation and development of its activities, can clarify a lot for the researcher and facilitate the choice of the necessary scientific tools. All these and many other areas of the modern theological method will be considered on the pages of a special issue of the journal.
