Let's take a look at scripture. In ancient Biblical times, people worshiped totems (graven images) because they believed these very images conveyed the power portrayed in the image. The Bible says we are not to worship idols. In Exodus, we see where the people melted down their gold to make a golden calf, and Aaron pointed to the calf and told them "There is your god who led you out of Egypt.) A graven image declared to be a god, a practice in ancient Biblical times.
God forbade that. He did not forbid images used for religious/holy purposes.
Example 1: Ark of the Covenant
God commands Moses to adorn the Ark of the Covenant with two graven images Cherubim.
Example 2: The Serpent
God said to Moses, "Make a fiery (bronze) serpent and raise it on a pole..." Those who looked at the bronze serpent God commanded to be engraved were healed.
Example 3: Solomon's Temple (1 King 6:22-29)
And he overlaid the whole house with gold, until all the house was finished. Also the whole altar that belonged to the inner sanctuary he overlaid with gold.
In the inner sanctuary he made two cherubim of olivewood, each ten cubits high. Five cubits was the length of one wing of the cherub, and five cubits the length of the other wing of the cherub; it was ten cubits from the tip of one wing to the tip of the other. The other cherub also measured ten cubits; both cherubim had the same measure and the same form. The height of one cherub was ten cubits, and so was that of the other cherub. He put the cherubim in the innermost part of the house; and the wings of the cherubim were spread out so that a wing of one touched the one wall, and a wing of the other cherub touched the other wall; their other wings touched each other in the middle of the house. And he overlaid the cherubim with gold.
He carved all the walls of the house round about with carved figures of cherubim and palm trees and open flowers, in the inner and outer rooms.
Graven images are constructed all over the place in the temple of God.
Example 4: Ezekiel's Time (Ezekiel 41)
We see the same engraved images in the Temple in Ezekiel's time.
Both inner and outer rooms were carved figures of cherubim with two faces...a man's face and and a lion's face.
*****
Basically, you take a verse or two in Exodus that says not to use graven images as idols. Clearly, there were graven images (and even more Bible passages) that speak of graven images use in places of worship for a holy purpose.
Instead of acknowledging the Biblical practice of using 'graven images' in holy places of prayer for holy purposes, you find a Bible passage that you believe excuses you from accusing/judging Catholics of being idol worshipers. I find that shameful.
