Because of the incarnation, Christ rules not just as Son of God and Creator of all things, but also Son of Man; His rule is based in trust: we trust Him because He is One of us and can be “touched by the feelings of our infirmities.”[2] In the half-dome icon you see the Holy Mother of God seated on a throne with the Christ-child on her lap. The image is clear. She, having given Him His Humanity, is that throne upon which she sits and He rules. She and the throne are one; she provides the cosmological platform to rule men as Man. Without this throne in and of the human race, His governance—while fully valid—would amount to tyranny because we would be ruled by a God and not a Man.
