(A). I think the proper rendering of the word in question is, "anyhoo," not "anywho." It is correctly said as "anyhow."
(B). I've always wondered where this little narrative came from. No doubt it originated with Mary, but from the little bit we know of her, she doesn't seem like someone who would tell this sort of detail to anyone outside her immediate family. How did it originate, and how did it make its way into the minds of the evangelists?
(C). It is ironic that possibly the most often repeated prayer in the Catholic collection (the Hail Mary) starts with words that were - it now seems - a mis-translation of the original text, to wit, we say, "Hail Mary, full of grace..." and most current translations render it as something like, "Hail Mary, you have found favor with the Lord..." And that translation is, as I understand it, the basis for our belief in the Immaculate Conception - that Mary herself (not Jesus) was conceived without original sin.
(D). Many of the details of this narrative have found no support among historians who have studied this part of the world at the time in question. The whole census thing, with Joe having to trek to his family's town of origin, the killing of the babies...there is no contemporaneous record of these events that would corroborate the Nativity narrative.
(E). The Nativity and Christmas should be celebrated separately, on the same calendar day. When viewed properly, there is no connection between the Nativity, and Christmas trees, gift-giving, Santa Clause, and jingle bells. I say, from sunset on Christmas Eve until sunrise on Christmas Day, we celebrate the Nativity, then from sunrise on, we celebrate "Christmas."
