Contradiction with Matthew 8:28
This verse contradicts Mark 5:1 as it describes the location as the country of the Gergesenes, whereas Mark 5:1 mentions the country of the Gadarenes.
Matthew 8:28: And when he was come to the other side into the country of the Gergesenes, there met him two possessed with devils, coming out of the tombs, exceeding fierce, so that no man might pass by that way.
Contradiction with Luke 8:26
This verse also names the location as the country of the Gadarenes as in Mark 5:1, but the differences in description and characters between the accounts can lead to perceived contradictions.
Luke 8:26: And they arrived at the country of the Gadarenes, which is over against Galilee.
Paradox #1
Mark 5:1 mentions that Jesus and his disciples arrived on the shore of the Gerasenes. A potential historical inconsistency here is that the town of Gerasa is far from the Sea of Galilee, making it unlikely to be the location described. Some scholars suggest it might be a textual error or that a different nearby region or town was intended.
