Kievan Christianity: Church and spatial-temporal identification

In the Ukrainian scientific literature, theology and journalism, the concepts of "Kievan Christianity", "Kyiv-Christian tradition of Volodymyr's baptism", "Ukrainian Orthodoxy" (not to be confused with "Orthodoxy in Ukraine"), "Churches of the Kiev Tradition "," Kiev Churches "," branches of the Kiev Church "," heirs of Vladimir baptism ", etc. However, analyzing the arguments in the disclosure of these concepts by different authors, we are confronted with the traditional problem of Ukrainian science - a variety of interpretations, engagement, and politicization of approaches. And in our case there is also a confessional approach, which many researchers can not always avoid.
