Continuing my reading of Jesus, Interrupted by Bart Ehrman, I'm on chapter two now where he's discussing contradictions in the Bible. He's not presenting an exhaustive list, but rather ones that "in the opinion of a large number of historical critics, cannot be reconciled without doing real violence to the text."
I'm excited to have some specific examples because as a Christian I would have this concern thrown at me every now and then by nonbelievers I had conversations with. "The Bible is full of contradictions!" they would say and I would ask for one to be named. And every single time no one would be able to give me an actual contradiction, which of course leaves the point at a dead end.
First up on Ehrman's list:
Mark and John say that Jesus died on different days
Mark, the earliest gospel, says that Jesus was crucified at nine in the morning on Passover (Mark 15:25). John has Jesus crucified around noon on the day of preparation for Passover (John 19:14) which is a day before. It is still the day of preparation when the Roman soldiers find Jesus dead (John 19:31-34).
For clarity, the day of preparation ended Friday night as the Sabbath begins at sundown on Friday. Meaning that Mark has Jesus crucified on Saturday morning and John has Jesus crucified Friday afternoon.
Ehrman posits that since John was written later, it's likely that the author changed the time of death to make a theological point: Jesus is the Lamb of God. John is the only gospel to give Jesus the title of Lamb of God. Jesus dying on the day of preparation for Passover means he's dying with all the lambs being ritualistically sacrificed as the Jews remember passover. The timing drives home the notion that Jesus is dying as a sacrifice so that others may be spared.
In my opinion, what we are left with at minimum is the certainty of irreconcilable differences between the gospel accounts that leave the door wide open for being able to doubt their accurate accounting of events. The impact of this could be pretty severe, when you believe that the Bible is completely inerrant with no inaccuracies or contradictions. If I was still a Christian, it would give me a lot to think about.
