How do I use just one category' posts on my home page?

Question

I have mainly protected categories, but I have one open category, how can I set it up so I load only the open catgeory posts to show on my home page

Answer 1

This should about do it for you, add args as needed

$args = array(
    //basic post data
    'posts_per_page' => 10,
    'post_type'      => 'post',
    'post_status'    => 'publish',
    //category
    'category_name'  => 'your-cat-slug'
);
$posts = new WP_Query( $args );

Docs: WP_Query

Answer 2

It would be better to filter the query on the home page instead of adding another one with WP_Query

add_filter( 'pre_get_posts', 'my_home_query' );
function my_home_query( $query ) {
 if( $query->is_home ) {
       $query->set( 'cat', $cat_id );
   }
     return $query;
}
