Can't get page contents to display

I built my own theme. I can get specific posts or post categories to display fine, but I can’t get any content on a static page to show up.
I tried making a new template for the static pages, but that doesn’t work either – it just pulls up posts. I can’t find any reference to displaying static page content in the codex, so any help would be appreciated.

Here is the page template I’m using:

<?php get_header(); ?>

		<div id="main_container">

			<?php get_sidebar(); ?>

				<section id="main_content">

				<?php while (have_posts()): the_post(); ?>
				<div class="maintitle"><?php the_title(); ?></div>
                <?php the_content(); ?>
				<?php endwhile; ?>

				</section>

			<?php get_footer(); ?>
