This is one of the top 10 Christmas myths on this list. Because Christmas is meant to commemorate the birth of Christ, some people believe that it is the most important Christian holiday. Actually, it is not. The most important Christian holiday is the Easter, where Christians commemorate the rising of Jesus Christ from death into eternal life. For Christians, the resurrection of Christ contained the promise of eternal life for those who believe in him, and it meant triumph over death. This holiday is so important that Christians spend nearly two months celebrating the season.
