Mark's Resurrection Account
I have read that the ending of the Gospel of Mark is considered to have been added much later and is not part of the original Gospel. What is the Catholic perspective on this?
The Resurrection account in Mark is much debated. However, even scholars who reject the Resurrection account as original to the Gospel do not hold that Mark rejected the Resurrection. Jesus predicted his resurrection in the Gospel of Mark (8:31, 9:31, 10:34). Of those who reject the Resurrection accounts in Mark, it is generally accepted that the Gospel ends at 16:8 with the empty tomb.
There two possibilities. Either the original verses following 16:8 were lost along the way, or Mark was giving us a theological challenge. He took great pains in his Gospel to show the authority of Jesus and his uniqueness. Jesus proclaimed that he would be resurrected; the question is, do we believe him? Mark may have concluded his Gospel with the empty tomb as a symbol that we all stand at the empty tomb challenged with whether we believe the words of Jesus or not.
