Easter or Resurrection Sunday is a festival and holiday celebrating the resurrection of Jesus Christ from the dead, described in the New Testament as having occurred on the third day of his burial after his crucifixion by Romans at Calvary. It is the culmination of the Passion of Christ, preceded by Lent (or Great Lent), a forty-day period of fasting, prayer, and penance.
On Easter Sunday, Christians celebrate the resurrection of the Lord, Jesus Christ. It is typically the most well-attended Sunday service of the year for Christian churches.
Christians believe, according to Scripture, that Jesus came back to life, or was raised from the dead, three days after his death on the cross. As part of the Easter season, the death of Jesus Christ by crucifixion is commemorated on Good Friday, always the Friday just before Easter. Through his death, burial, and resurrection, Jesus paid the penalty for sin, thus purchasing for all who believe in him, eternal life in Christ Jesus.
