We need to understand that even though God does not change, over time he changed His requests for people. The rituals of the mozaic law were a simbol and pointed to Jesus and the way God was about to deal with christians. Here is more info on this:

You are right, this is their biggest misunderstanding. They try to mix mozaic law with christianity, but Jesus said he was the end of the law. After His death God revealed a new way of dealing with people, and He also reveald the Sacred Secret to Paul. This is something jw's do not get. They created a hybrid of from mozaic law and christianity. But this is not what God wants in the way He deals with us today, after the sacrifice of His Son.
