Those two angels were the only 3D images allowed in the Temple and they were in noway venerated. It was the contents of the Ark that was venerated. One of the first commandments is of the 10 Commandments is that God forbidds the use of statues. Orthodox Christians follow the Ten Commandments of God and all his laws because Jesus did say that He did not come to change the laws but to fulfill them. Tell me then, if God did not forbid statues then why do Muslims and Jews prohibit them? Why was there an iconoclast movement during the Roman Empire? They were using God's timeless laws as arguments. I am a Roman scientist who lives in Constantinople and coming from an ancient race that used to worship statues, I know well that no matter what your argument is, in time your prayers soon are directed to the statue itself. Also statues are an excellent abode for demons who use them against us. Through out the early christian era and Old Testament, there are numerous stories of demons abiding in statues and using them as means to ensnare whorshippers.
The usage of statues is a primitive form of whorship used by the ancients. We Orthodox have icons b/c we know that Mary the Theotokos blessed the usage of icons not statues. An icon is a mysterious window into Paradise and therefore we use them as a passage for our prayers along with incense. A statue however is like a television set vs books; in the later you expand your mind when you read a book but in the former you benefit not your mind and in some cases may even cause damage to neurons in the brain. Similarly, using an icon forces ones spirit to concentrate on Paradise, exersizing our spirits.
If you want to use icons in your worshipp that is fine. However, it does not make it right nor should you say it is okay especially since it is one of the Ten Commandments. For thousands of years God's old people, the Hebrews, worshipped Him without statues out of old. And now the new people of God, Orthodox Christians, also worshipp Him without statues now and forever.
God is Great. He is everywhere....in the air the we breath, in the other side of the universe at the same time. How erronous it is to depict this God in three-dimensional form. My spirit trembles in fear at such a daring thought.
