One universal constituent element of human consciousness is belief in the existence of a divine reality that is experienced by persons as the most intimate and essential part of human life. Belief in transcendent reality, which is an immanent part of human nature, constitutes an awe-inspiring mystery — that is, a theantropy. Strictly speaking, ‘theantropy’ is a theological term which is used to express the "union of the divine and human natures in Christ". The novum of my understanding of theantropy (...) consists in the application of the concept to the phenomenological experience of the religious consciousness of humanity. Henceforth, I designate theantropy to mean an ontic union and an inherent disposition of the ‘human’ and ‘divine’ constituents in/of every human being. I will examine and reflect on theantropy as the philosophical principle of religious ecumenism as well as compare various solutions of theantropy not only with regard to a particular system of beliefs, but as it is experienced in each and every human being by following Augustine’s principle: "In interiorem hominem redi: ibi habitat Deus".
