How to display private topics outside WordPress?

Hello,

I would like WordPress to use as a edit tool and my website as a renderer, but don’t want to posts created for website display on my blog. So I did this on my website:

– created private post
– put on website this:

define('WP_USE_THEMES', true);
require('blog/wp-load.php');

$args = array(
	'post_status'      => 'private',
	'p'    => '3019'
);
query_posts( $args );

?>

<?php while (have_posts()): the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php the_content(); ?>

<?php endwhile; ?>

Unfortunately it does not work.

When i set p to post id that is published it works.
When i publish my private post as public it works too.
But when post is private it does not work.

What to do to make this work?
