This program is part of a series that investigates some of the mysteries of the Bible. In this episode, narrated by Richard Kiley and Jean Simmons, the investigation turns to the nativity of the Christ child. The program inquires into the particulars, including the actual date and place of the birth of Jesus. Do the facts support the story that He was born in Bethlehem in a stable on December 25? Or was the story devised to coincide with older traditions? Historians and theologians discuss the evidence; art and reenactments are used to illustrate their findings.
