What strikes me is that all four gospels do not describe the actual resurrection … we just see an empty tomb. The Gospel of Peter, a non-canonical gospel, gives more of a description, but I’m not sure how authentic it’s considered to be.
Also, I think it’s interesting that Mary, a woman, is the first to find the empty tomb … that John(?) gets to the tomb before Peter … that Peter enters the tomb first … that John believes in the resurrection first.
Did the resurrection really happen? Does it matter? I’d say yes to both questions. Here’s a page with biblical info on the resurrection by Felix Just sj. But to say it simply, I’ll quote Paul … And if Christ has not been raised, then our preaching is vain, your faith also is vain.
