In the New Testament, after the Romans crucify Jesus, he is anointed and buried in a new tomb by Joseph of Arimathea but God raises him from the dead[ and he appears to many people over a span of forty days before his ascension to Heaven, to sit at the Right Hand of God. Christians celebrate the resurrection of Jesus on Easter Sunday, the third day after Good Friday, the day of his crucifixion. Easter's date corresponds roughly with Passover, the Jewish observance associated with the Exodus, that is fixed for the night of the Full moon near the time of the spring equinox.
The Apostle Paul wrote that "Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures".[1 Cor. 15:3b-4] Thus the death and resurrection of Christ were proclaimed as belonging together at the very heart of the gospel, forcefully placing “the full weight of faith on both the death and resurrection of Jesus Christ” by stating, “if Christ has not been raised, our preaching is useless and so is your faith”.[1 Cor. 15:14] In fact, Paul further claims that belief in the death and resurrection of Jesus is so central to salvation that “if Christ has not been raised, your faith is futile; you are still in your sins. Then those also who have fallen asleep in Christ are lost. If only for this life we have hope in Christ, we are of all people most to be pitied.[1 Cor. 15:17-19]
At daybreak on the first day of the week the women who had come from Galilee with Jesus
took the spices they had prepared and went to the tomb.
They found the stone rolled away from the tomb; but when they entered, they did not find the body of the Lord Jesus.
While they were puzzling over this, behold, two men in dazzling garments appeared to them.
They were terrified and bowed their faces to the ground.
They said to them, “Why do you seek the living one among the dead?
He is not here, but he has been raised.
Remember what he said to you while he was still in Galilee,
that the Son of Man must be handed over to sinners and be crucified, and rise on the third day.”
And they remembered his words.
Then they returned from the tomb and announced all these things to the eleven and to all the others.
The women were Mary Magdalene, Joanna, and Mary the mother of James; the others who accompanied them also told this to the apostles,
but their story seemed like nonsense and they did not believe them.
But Peter got up and ran to the tomb, bent down, and saw the burial cloths alone; then he went home amazed at what had happened.
