… A similar claim can be made for the Eastern Orthodox understanding of the icons. The Orthodox Church’s veneration of icons flows from the logic of patristic theology. The Orthodox theological system rests on two premises: (1) that God is utterly transcendent and unknowable, and (2) that God’s transcendence has been bridged through the Incarnation.
For Orthodox Christians the Incarnation forms the basis for the icons.’
