Of course it does. Look at the history. Christ's crucifixion and resurrection coincided with Passover. How on earth can you say Easter has nothing to do with Passover?
Are you Christian or Jew? Do you celebrate Passover and not Christ's resurrection?
Really? Easter and Passover can be as much as three weeks apart. So is Palm Sunday "liturgically related" related to St. Patrick's Day, because after all, they're less than two weeks apart? Valentine's Day was only four days before Ash Wednesday. Are they "liturgically related" too?
Of course it does. Look at the history.
Do you know what Jews believe about Jesus' resurrection?
