Gabriel's Revelation, a piece of stone with ink writing dating to the time of Herod's Temple, is on display in Houston as part of a new exhibition "The Birth of Christianity: A Jewish Story" presently showing at the Houston Museum of Natural Science. 

The Houston Chronicle's Barbara Karkabi introduces the exhibition in the Chronicle's Houston Belief with the question:

Did Christianity begin with the birth of Jesus and his death on the cross 33 years later? Or were its roots buried deeply in ancient Judaism?

In raising that question, Karkabi takes the whole issue of the roots of Christianity out of its perceived origins and invites the reader and viewer to consider Christianity in its Jewish milieu. In doing so, the question of celebrations on December 25 is called into question.
