Easter is the most important festival in the Christian calendar. It celebrates God raising his son, Jesus, from the dead, which for Christians symbolises Jesus’ destruction of the power of sin and the possibility of an afterlife in Heaven. Christians remember the events of the last week of Jesus’ life (before his crucifixion) during Holy Week. Holy Week ends with Easter Sunday, which is the day when Christians celebrate Jesus’ resurrection.
The Gospel of Mark (15:21–41) describes the events of Jesus’ crucifixion:
My God, my God, why have you forsaken me?
Surely this man was the Son of God!
Most denominations of Christianity teach that Jesus’ crucifixion happened just as described in the Bible. The crucifixion is important for Christians who believe that God sacrificed Jesus, his only son, to atone for the sins of humanity. For some Unitarian and Quaker Christians who not believe that Jesus was the son of God, the crucifixion is not of significance. For these Christians, the Eucharist, which celebrates Jesus’ crucifixion, is not a feature of their worship.
