In the books of Moses, God told his people to keep several annual festivals: Passover, Unleavened Bread, Pentecost, Trumpets, Atonement, and Tabernacles. Are these festivals still required for Christians? We analyze the biblical evidence and conclude that no, we do not have to keep them. Then what were they for? We look at how these festivals had details that symbolized the work of Jesus Christ. Even so, not all details have symbolic meaning.
