Have posts included on a page that share same category

Question

I'm new to Wordpress so please bear with me. I have created a site with two levels of hierarchy: top level and secondary level. The secondary pages are grouped below corresponding top level pages.

I see that page content is retrieved using page.php. I also see from page.php that the existence of content is tested by have_posts() and retrieved using the_post().

How could I achieve having two different types of content on the the same page: "static" or evergreen page content at the top, and posts sharing the same category underneath? I have Googled this all day and not found a satisfactory answer.

Thanks.

(…) are pages in fact posts?

You won't think what every thing is a post type in WordPress: Posts, Pages, Links, Nav Menu items... The same goes for Terms, Categories and other things, which are built in Taxonomies.

You can take a look at it with adding the following very late in your theme (the footer for example).

echo '<pre>'.var_export( wp_list_pluck( $GLOBALS['wp_post_types'], '_builtin' ), true ).'</pre>';

(…) "static" or evergreen page content at the top, and posts sharing the same category underneath (…)
