The 10 Commandments appear in 2 books of the old testament. Exodus and Deuteronomy. That is a deliberate misinterpretation of the term idols. Most pegan religions of the time had idols of their many gods and the worship was directed at those idols. There is nothing wrong with some pictures and statues to remind us of God and Jesus and other important figures from the Bible. It's just like having pictures of your family to remind you of them. We are not worshiping the image we are worshiping God. Mary is not worshiped but honored as the mother of God. She was made special by God since he chose her to bear his son Jesus. I do like the artwork and statues to remind us of these important ideas. Not sure what you mean by worship Peter and kiss his feet? No one but God is worshiped!
