Contradiction with Matthew 28:2-4
These verses describe how the stone was rolled away by an angel before the people arrived, contradicting John 20:6 where the stone is already removed without mention of the angelic intervention.
Matthew 28:2-4: And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it. [was: or, had been]
Contradiction with Mark 16:4
This verse says the stone was already rolled back when the women arrived, emphasizing their surprise, which contrasts with John 20:6 where description is more focused on the physical observation by Peter, rather than on the act of rolling away the stone.
Mark 16:4: And when they looked, they saw that the stone was rolled away: for it was very great.
Contradiction with Luke 24:2
Luke notes the stone was already moved away, aligning with John 20:6, but the subsequent narrative focuses more on the women and angels rather than the male disciples who are central in John's account.
Luke 24:2: And they found the stone rolled away from the sepulchre.
