Abstract
In this article the authors have done work on the analysis of the discourses of state interaction and religious confessions in the Christian world during the middle Ages and Renaissance. One of the problems associated with the interaction of the state and religion and religious organizations is the concept and essence of this phenomenon. A historical analysis of the development of this aspect of interaction in the Christian world is also considered. As part of the analysis of this aspect, an overview was given of medieval thinkers and their ideas: in particular Thomas Aquinas and Augustine Aurelius. A brief analysis of the main events related to the development of the interaction of religious faiths and the state in the Christian world in the given period of time was also made. Thus, there is a certain reproduction of religious relations on the background of social relations. The emphasis was also placed on the development of this interaction and its impact on the development of society. For a deeper analysis of this topic, it is necessary to classify in more detail the concepts and essence of this direction.
