The Bible makes no mention of Easter or Easter Monday. There is no requirement as a church to celebrate it, but there is prohibition either.
Easter Monday as we know is the day after Christ’s resurrection where he said for 40 days appearing to believers and giving ministry. He also healed the sick and proved to doubter’s he was the son of God.
Easter Monday, also called Bright Monday or Renewal Monday, is the beginning of Bright Week. It is common to douse people in water, representing the new life of baptism, and play games with Easter eggs. Such as Easter egg hunt or rolling your a hard boiled egg down a hill (which represents the stone being rolled away).
