I honor all matter, and venerate it. Through it, filled, as it were, with a divine power and grace, my salvation has come to me. Was the three-times happy and blessed wood of the Cross not matter? Was the sacred and holy mountain of Calvary not matter? What of the life-giving rock, the Holy Tomb, the source of our resurrection — was it not matter? Is the holy book of the Gospels not matter? Is the blessed table which gives us the Bread of Life not matter? Are the gold and silver, out of which crosses and altar-plate and chalices are made not matter? And before all these things, is not the body and blood of our Lord matter? Either stop venerating all these things, or submit to the tradition of the Church in the venerating of images, honoring God and his friends, and following in this the grace of the Holy Spirit. Do not despise matter, for it is not despicable. Nothing that God has made is. Only that which does not come from God is despicable — our own invention, the spontaneous decision to disregard the law of human nature, i.e., sin.
