"It's the usual muddle about times, Pole."
- C.S. Lewis
[9] And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition. - Mar 7:9 KJV
Mary was not in any way, shape, form or fashion sinless. She was born with the sin nature, passed down from generation to generation from Adam, just like the rest of us. If you can show where Mary was born of a virgin and therefore without the sin nature, by all means please do.
