St. Maximus the Confessor (580-662 A.D.) understands the cosmos through a theological ontology of Love. All creatures in creation are unified through participation in the ecstatic Love that is the life of the Trinity. Participation in this Love unifies the difference of creatures into a harmony. As such this love is the “reason” or “logos” of creatures. With the fall of humanity this love is disrupted cosmically. The fall of humanity is key in this “cosmic tragedy” for humanity is the microcosm (micros-kosmos or “little cosmos”), which participates in the sensuous creaturely dimension of being and the rational-spiritual dimension of the hierarchy of being. Humanity, the microcosm, is the center or crux of the hierarchy of being as it co-inheres in the second person of the Trinity, the Logos. It is the crossing of the divine and the sensuous dimensions of the hierarchy of being. Consequently, when humanity falls the harmony of creation is disrupted.
