get_header() not working outside wp directory

I can pull in the wordpress directory and can successfully use wp-loop to go through posts. However, the header will not pull in. If I use an include instead, the header will get pulled in, but will throw an error on semantic_body().

<?php
define('WP_USE_THEMES', false);
require('../../wp-blog-header.php');
get_header();
// I've tried this and it successfully pulled in the header
//   code but threw an error on semantic_body()
// @include_once('/wp-content/themes/mytheme/header.php');
query_posts('category_name=help');
while (have_posts()) : the_post(); ?>
  <div id="post">
    <h3><a><?php the_title();?></a></h3>
    <?php the_content( 'Read more' ); ?>
  </div>
<?php endwhile; ?>

The error I get when I use include instead of get_header() is:

Fatal error: Call to undefined function semantic_body() in
