Biblical Archaeology Review has a free book in pdf format entitled The First Christmas, with perspectives from Biblical scholars about subjects such as the star and the birthplace of Jesus.
There are some interesting Christmas perspectives around the blogosphere. Robin Parry recommends taking Christ out of Christmas. Richard Hall offers a defense of materialist Christmas, suggesting that it is the rest of the year that is the problem. Bruce Prescott shared a link to a Street Prophets piece on how to put Christ back into Christmas. Experimental Theology talks about the “real” war on Christmas and whether Santa is real, while Brian LePort is thinking about the real Santa Claus.
And for musical accompaniment, David Ker offers a phonetically similar variation on a Christmas favorite.
