Telling you that Catholics worship statues, is definitely a lie. I was quoted Exodus 20: 4-5. This is where Moses was given the command not to carve any graven image as an idol and not to worship it. But then God commands the carving of images in Exodus 25: 18-19. There's also Moses having a serpent on a pole, in Numbers 21: 8-9. And in Kings the temple had engraved cherubim, trees, flowers, bronze lions, oxen, and even pomegranates.
See? God explicitly commands graven images to be built. The difference is that God isn't condemning the use of statues per se. It's how you use the statue, e.i., inspiration, visual aid, etc. Idolatry is condemned. Using the statue as a picture of a loved one, a remembrance, etc., is not worshipping it. Heck, I kneel beside my bed at night, to pray. To say that I'm worshipping my bed, is a bald-faced lie.
