Some gospels say Jesus was crucified with two thieves, though the Romans never crucified thieves.
Mark - The two thieves are mentioned, but there is no conversation
Matthew 27:44 - The two thieves taunt Jesus
Luke 23:39-42 - One thief taunts Jesus and is criticized by the other. Jesus promises the 2nd thief that they would be in Paradise that day, though John and Acts say he did not ascend to heaven until 40 days after his resurrection
John - The two men aren’t described as thieves
Jesus is given something to drink while he is on the cross, but what?
Mark 15:23 - Jesus is given wine mixed with myrrh, but he doesn’t drink
Matthew 27:48, Luke 23:36 - Jesus is given vinegar, but he doesn’t drink
John 19:29-30 - Jesus is given vinegar and he drinks
Romans supposedly witnessed Jesus’ crucifixion, but what did they think?
Mark 15:39 - A centurion is cited as saying: “Truly this man was the son of God!”
Matthew 27:54 - A centurion is cited as saying: “Truly this was the son of God.”
Luke 23:47 - A centurion is cited as saying: “Truly this man was innocent.”
John - No centurions say anything
The gospels describe several woman as having followed Jesus around, but what did they do when Jesus was crucified?
Mark 15:40, Matthew 27:55, Luke 23:49 - Several women watch Jesus from afar
John 19:25-26 - Several woman are close enough that Jesus could talk to his mother, contrary to Roman practices
Mark 15:25 - Jesus was crucified on the “third hour.”
John 19:14-15 - Jesus was crucified on the “sixth hour.”
Matthew, Luke - It’s not stated when the crucifixion starts, but the “sixth hour” occurs during the crucifixion
Jesus’ last words before dying are important, but no one seems to have written then down.
Mark 15:34-37, Matthew 27:46-50 - Jesus says: “My God, my God, why hast thou forsaken me?” (but they use different Greek words for “God” — Matthew uses “Eli” and Mark uses “Eloi”)
Luke 23:46 - Jesus says: “Father, into thy hands I commit my spirit.”
John 19:30 - Jesus says: “It is finished.”
Moment of death..
Matthew 27:51-53 - At the moment Jesus dies, a massive earth quake strikes and opens tombs where dead people rise again
Mark, Luke, John - No earthquake is mentioned. No earthquake and no massive influx of formerly dead people is mentioned in any historical records, which is strange given how monumental such an event would be.
