Freedom From Religion Foundation has made a straightforward Challenge for those who consider themselves Christians:
My challenge is simply this: tell me what happened on Easter. I am not asking for proof. My straightforward request is merely that Christians tell me exactly what happened on the day that their most important doctrine was born.
Believers should eagerly take up this challenge, since without the resurrection, there is no Christianity. Paul wrote, “And if Christ be not risen, then is our preaching vain, and your faith is also vain. Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not.” (I Corinthians 15:14-15)
The conditions of the challenge are simple and reasonable. In each of the four Gospels, begin at Easter morning and read to the end of the book: Matthew 28, Mark 16, Luke 24, and John 20-21. Also read Acts 1:3-12 and Paul’s tiny version of the story in I Corinthians 15:3-8. These 165 verses can be read in a few moments. Then, without omitting a single detail from these separate accounts, write a simple, chronological narrative of the events between the resurrection and the ascension: what happened first, second, and so on; who said what, when; and where these things happened.
The trick is that the Bible is riddled with contradictions on this alleged story. Many of those contradictions are outlined in the article. Here are a few:
Who were the women?
Matthew: Mary Magdalene and the other Mary (28:1)
Mark: Mary Magdalene, the mother of James, and Salome (16:1)
Luke: Mary Magdalene, Joanna, Mary the mother of James, and other women (24:10)
John: Mary Magdalene (20:1)
What was their purpose?
Matthew: to see the tomb (28:1)
Mark: had already seen the tomb (15:47), brought spices (16:1)
Luke: had already seen the tomb (23:55), brought spices (24:1)
John: the body had already been spiced before they arrived (19:39,40)
Was the tomb open when they arrived?
Matthew: No (28:2)
Mark: Yes (16:4)
Luke: Yes (24:2)
John: Yes (20:1)
Who was at the tomb when they arrived?
Matthew: One angel (28:2-7)
Mark: One young man (16:5)
Luke: Two men (24:4)
John: Two angels (20:12)
