Mutual relationship between Pneumatology and Christology is important for proper understanding of both of them as well as Ecclesiology. There are two extremes in understanding of these two moments in Economy of salvation, both in Eastern and Western theology. Western Christomonism stands on one side and eastern Pneumatomonism is on the other. Such extreme understandings lead to misunderstanding of Ecclesiology. Proper understanding of Ecclesiology requires that these extremes are set aside and it also requires a synthesis of Christology and Pneumatology.
