Contradiction with Matthew 28:6
This verse supports, rather than contradicts, Mark 16:6 by similarly stating Jesus is not in the tomb and is risen.
Matthew 28:6: He is not here: for he is risen, as he said. Come, see the place where the Lord lay.
Contradiction with John 20:2
This verse indicates confusion with the idea that Jesus' body was taken, which contrasts with the assurance given in Mark 16:6 of Jesus's resurrection.
John 20:2: Then she runneth, and cometh to Simon Peter, and to the other disciple, whom Jesus loved, and saith unto them, They have taken away the Lord out of the sepulchre, and we know not where they have laid him.
Paradox #1
Mark 16:6 may be seen as inconsistent with the accounts of the resurrection found in other Gospels. The differences in details such as who visited the tomb, what they saw, and what they were told can create confusion about the events surrounding the resurrection. These variations can be seen as contradictions or inconsistencies in the narratives.
