“The father… Son… and holy Spirit glorify each other… At the center of the universe, self-giving love is the dynamic currency of the Trinitarian life of God. The persons within God exalt, commune with, and defer to one another….. When early Greek Christians spoke of perichoresis in God they meant that each divine person harbors the others at the center of his being. In constant movement of overture and acceptance each person envelops and encircles the others.”
