Pull the content out of a page

While inside a query loop, this function will output the current posts title:

the_title();

This function will output the content:

the_content();

What I suspect has happened however is that you are instead calling get_template_part( 'content', 'page' ); and expecting it to output the content for the page, when what it’s actually doing is checking if there’s a content-page.php, and including it if it’s present, if not it checks for content.php and includes that, and because neither exist, it’s doing nothing, and so you get no content.

For more details on what get_template_part actually does, look here:

EDIT*
Working snippet:

<?php while ( have_posts() ) : the_post(); ?>
     <?php the_title(); ?>
     <?php the_content(); ?>
<?php endwhile; // end of the loop. ?>
