You also might be in the mood for a Christmas book.
John Dominic Crossan and Marcus Borg have published another book in time for Advent entitled The First Christmas: What the Gospels Really Teach About Jesus's Birth.
This is from the publisher:
"...they explore the beginning of the life of Christ, peeling away the sentimentalism that has built up over the last two thousand years around this most well known of all stories to reveal the truth of what the gospels actually say. Borg and Crossan help us to see this well-known narrative afresh by answering the question, "What do these stories mean?" in the context of both the first century and the twenty-first century. They successfully show that the Christmas story, read in its original context, is far richer and more challenging than people imagine."
