The Historical Society for the History of Christianity is a professional organization that was established by a group of historians to raise awareness of the importance of the influence of the history of Christianity on social history in general, with a special focus on the Balkan and Slavic peoples in particular. Although the society was established by a group of historians as a professional organization, its members, at the decision of the founders, may also come from other professions, who directly or indirectly, through their work, deal with the history of Christianity or some of its segments.

The Society deals only with historical segments of the history of Christianity, i.e. the Christian Church, until the schism of 1054 as a whole, and then only with Orthodox Christianity, without engaging in theological considerations, which belongs as a prerogative of the Church, but rather through the presentation of the history of the development of Christianity, i.e. the Christian Church, its structure, development, relations with states over time, and other social factors.
