Why is the paschal mystery important?

The paschal (Easter) mystery is the death and resurrection of Jesus.

The Paschal candle is a large, white candle used liturgically in the Western Rites of Christianity (Roman Catholic, Anglican, Lutheran, etc.). A new Paschal candle is blessed and lit every year at Easter, and is used throughout the Paschal season and then throughout the year on special occasions, such as baptisms and funerals.
