I'm sure other members of the godless media made this same mistake all over the country. But the only place I spotted it was in USA Today. When they reviewed "The Nativity Story," they described Mary's pregnancy as "the immaculate conception." Nope. For Christians, the Immaculate Conception refers to the birth of MARY - who was born without original sin because she was going to bear Jesus. (She's the only one in history, other than Adam, Eve and Jesus.) Her own pregnancy is referred to as the Virgin Birth. No biggie, USA Today -- most Christians get this wrong as well.
NOTE: Priv8Pete says I should refer to Catholics only, since most Protestants (the heathens) don't accept the concept of Mary being born without original sin. Fair enough, but I strongly think he's wrong when he suggests that Protestants have taken the name for that Catholic doctrine and re-defined it to mean exactly what people often confuse it to mean: the birth of Jesus by a virgin. Here's the Wikipedia discussion and here's the Pope's pronouncement on the Immaculate Conception in the 1854 (one of only two times the Pope has spoken with the weight of infallibility) and I can't find any mention anywhere of an alternate meaning to this Catholic concept. Sorry, but it's ours and you interpret it wrong and you'll have to find me a reputable reference to prove me mistaken. Talk to your religios advisedr and get back to me.
