The author of this article refers to Husserl’s principle that every science should be justified by the experience appropriate to itself, and also refers to the recognition of as many types of experience as there are types of reality. Thus, the author proves in his article that through the power of Christian Faith, Hope and Love and through the power of the gifts of the Holy Spirit we are capable of meeting God who manifests Himself and redeems us in the Mystery of Christ. The author also points out that this specific visuality of Faith, Hope and Love with the sensations of the actions of the Holy Spirit form the basis of Christian Experience, common and mystical. The Christian Experience defined in such a way should be the source of theological cognition in general and be the source of academic cultivation of principal and formal theology. Theology that has its source in such an experience should also be verifiable by the criterion of such an experience. In this sense, Christian Theology is not a rationalistic and naturalistic inference from the Texts of the Holy Bible and Magisterium Ecclesiae, but is a formal explication and interpretation of the aforementioned Christian Experience. The author also argues that the ecclesiastical characteristics of Christian Experience excludes its individualistic perception and does not diminish the role of Magisterium Ecclesiae in the fact of the experience itself and the cultivation of Theology as the explication and interpretation of experience.
