I want to clear something up, as it has been coming up (for some reason) a lot lately.
I am not Catholic but it really bothers me how widely a particular doctrine of the Catholic Church is misunderstood (even by Catholics). "The Immaculate Conception" does not--repeat, does not--refer to Mary's pregnancy with Jesus. It does refer to Mary being conceived in the womb of her mother, Anne, the old-fashioned way (the ole in-out, in-out), albeit without the stain of original sin. Is this clear...? Mary was immaculately conceived. Jesus was, of course, born without original sin as well, but He was God, so that's kind of a given.
