That reminds me of the old joke. Jesus comes across a crowd of people about to stone an adulteress to death. He orders the crowd to stop and reminds them, "Whoever among you is without sin may cast the first stone!" A little old lady limps forward, picks up a giant rock, throws it at the adulteress and instantly kills her.
Shaking his head, Jesus says, "Aw, Mom!"
That's pretty dang funny!
I always had heard the joke as after Jesus says, "Let him who is without sin...," he's hit in the head with a stone and says, "You know, mom, sometimes you really piss me off."
Anyway, to chime in on the related Catholic position on Mary's status, the Church teaches that because of the Immaculate Conception (which most Catholics erroneously believe refers to the Virgin birth), Mary was born without original sin and therefore was sinless and incapable of sin during her life. The Catholic Church teaches that Mary was also assumed into heaven, body and soul, though there has been uncertainty in the Church as to whether Mary actually physically died.
Most of us look at our mothers as sinless.
