Here's my theological argument: we Catholics and Orthodox worship God how He told us to worship Him, in the Holy sacrifice of the Mass, where His body is offered to the Father. You are dumbfounded by bowing down to statues and icons because you, being Protestant, don't know how to worship. You think that your congregations do worship. They don't. They read the Bible together, listen to their semi-educated pastor about what his thoughts are, and understand on the average zilch. Then they turn around and lecture others.
Leave your sect and come to Jesus.
“You are dumbfounded by bowing down to statues and icons because you, being Protestant, don’t know how to worship.”
I’m not dumbfounded, I just object to it. God objected to it too, so I think I’m in good company, at least in that regard.
