By the default, the Genesis child theme called Outreach Pro displays categories posts as excerpts. If you want to display the full content on just one category, Sridhar Katakam talks about it in his blog post. I changed the function names to fit my own, so here’s my own version of the code:

<pre lang="php">
// display full content on blog category
add_action( 'genesis_before_loop', 'urr_full_content_specific_category' );
 
function urr_full_content_specific_category() {
  if (is_category('blog')) {
		remove_action( 'genesis_entry_content', 'genesis_do_post_content' );
		add_action( 'genesis_entry_content', 'urr_do_post_content' );
	}
}
function urr_do_post_content() {
	the_content();
}
