Abstract
The purpose of this article is to examine the topic of the filioque as a current example of the relationship between the influence of historical causes on the formation of theology, theological formulations, and the practice of piety, down to the role of cultural context in the development of Christian doctrine. This article is not intended to reconcile the controversies surrounding the topic of the Filioque, nor is it intended to find a new theological solution to this theological question. The aim is to stimulate a practical perception of the theological debate about the understanding of the Holy Spirit within the doctrine of the Trinity among evangelical Christians in the post-Soviet space. The distortion of the doctrine of the Trinity has a direct impact on shaping the practice of the spiritual life. Therefore, evangelical Christians can and should reflect on the relationship between the doctrine of the Trinity and the practical life of Christians.
