Further on in this first part of his text “On Holy Images”, Saint John summarises the inherent goodness of matter. Christianity has, in the past, tended towards a kind of dualism which can demote the physical and material to a ‘lower’ level; in fact, God’s Creation is inherently capable of being “doxological, eucharistical’ – capable of giving glory and thanks – to Him and we, as the priests of His Creation, are given gifts to use the Creation in a way to worship Him clearly.
Of old, God the incorporeal and uncircumscribed was never depicted. Now, however, when God is seen clothed in flesh, and conversing with men, (Bar. 3.38) I make an image of the God whom I see. I do not worship matter, I  worship the God of matter, who became matter for my sake, and deigned to inhabit matter, who worked out my salvation through matter. I will not cease from honouring that matter which works my salvation. I venerate it, though not as God. How could God be born out of lifeless things? And if God’s body is God by union (kaq upostasin), it is immutable. The nature of God remains the same as before, the flesh created in time is quickened by a logical and reasoning soul. I honour all matter besides, and venerate it. Through it, filled, as it were, with a divine power and grace, my salvation has come to me. Was not the thrice happy and thrice blessed wood of the Cross matter? Was not the sacred and holy mountain of Calvary matter? What of the life-giving rock, the Holy Sepulchre, the source of our resurrection: was it not matter? Is not the most holy book of the Gospels matter? Is not the blessed table matter which gives us the Bread of Life? Are not the gold and silver matter, out of which crosses and altar-plate and chalices are made? And before all these things, is not the body and blood of our Lord matter? Either do away with the veneration  and worship due to all these things, or submit to the tradition of the Church in the worship of images, honouring God and His friends, and following in this the grace of the Holy Spirit. Do not despise matter, for it is not despicable. Nothing is that which God has made. This is the Manichean heresy. That alone is despicable which does not come from God, but is our own invention, the spontaneous choice of will to disregard the natural law,–that is to say, sin. If, therefore, you dishonour and give up images, because they are produced by matter, consider what the Scripture says: And the Lord spoke to Moses, saying, “Behold I have called by name Beseleel, the son of Uri, the son of Hur, of the tribe of Juda. And I have filled him with the spirit of God, with wisdom and understanding, and knowledge in all manner of work. To devise whatsoever may be artificially made of gold, and silver, and brass, of marble and precious stones, and variety of wood. And I have given him for his companion, Ooliab, the son of Achisamech, of the tribe of Dan. And I have put wisdom in the heart of every skilful man, that they may make all things which I have commanded thee.” (Ex. 31.1-6)  And again: “Moses said to all the assembly of the children of Israel: This is the word the Lord hath commanded, saying: Set aside with you first fruits to the Lord. Let every one that is willing and hath a ready heart, offer them to the Lord, gold, and silver, and brass, violet, and purple, and scarlet twice dyed, and fine linen, goat’s hair, and ram’s skins died red and violet, coloured skins, selim-wood, and oil to maintain lights and to make ointment, and most sweet incense, onyx stones, and precious stones for the adorning of the ephod and the rational. Whosoever of you is wise, let him come, and make that which the Lord hath commanded.” (Ex. 35.4-10) See you here the glorification of matter which you make inglorious. What is more insignificant than goat’s hair or colours? Are not scarlet and purple and hyacinth colours? Now, consider the handiwork of man becoming the likeness of the cherubim. How, then, can you make the law a pretence for giving up what it orders? If you invoke it against images, you should keep the Sabbath, and practise circumcision. It is certain that “if you observe the law, Christ will not profit you. You who are justified in the law, you  are fallen from grace.” (Gal. 5.2-4) Israel of old did not see God, but “we see the Lord’s glory face to face.” (IICor. 3.18)
