Actually that is not true. They talk about a sinful woman. They never say what the sins are, and they never mention the woman by name. I do read the bible, because it is part of my homework. The bible is a book written in allegory, and for those who are able to know the allegory, are able to better understand the bible. To many people have been taught to just to accept the faith of the preacher, priest what have you.
To many people say that God is a mystery, yet Jesus says "Ask and the mysteries of god shall be revealed." So how mysterious can it be, if you are able to find out.
