How are we to celebrate the new moon? Should we follow the exile calendar? How was the new moon determined in the first century? What is the role of the Sanhedrin? Will we celebrate the new moon in the Messianic Era? How should we celebrate the new moon today. The nation of Israel is like the moon. Just as the moon goes through various phases of decline and renewal each month so does the nation of Israel. The rebirth of the moon is likened to us being 'born again' in Messiah. The rebirth of the moon is likened to the restoration of the tabernacle of David and the two houses of Israel.
