    if (isset($_POST['submit'])) { 
      $error = array();
      if (empty($_POST['request'])) { $error .= "<li>Prayer Request is Empty</li>";}
      if (empty($_POST['phone']))   { $error .= "<li>Please enter a valid phone Number</li>";}
      if (empty($_POST['response'])){ $error .= "<li>Please choose a way to contact you.</li>";}
      ?>
          <div class='Errors' >
          <?php print_r ($error); ?>
          </div>

Well what did you expect with $error = array()?

Try $error = ""; instead.
