I'm not trying to start an argument! I thought I should make that clear.
I have a boss who's Catholic.  He made a comment about how Mary, Jesus's mom, never sinned.  I didn't know that.  I believed that she had to sin because in Luke it states that she had to offer a "sin offering" after Jesus was born and in Romans it states that ALL have sinned.  I was just wondering if the Catholic bible/teachings had any changes on those topics.  I'm not saying one is right or the other is wrong, I just like to know about different religions.
TIA!
