Help with query_posts, pagination and Read More

Hi, I am trying out using query_posts, but pagination and Read More somehow does not work properly.

For pagination, I know that I can add the necessary template tags for the Previous Entries and Next Entries link, but I can’t seem to get the page numbers to work.

The page numbers code (in content.php) is as follows:

wp_link_pages( array(
				'before'      => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfifteen' ) . '</span>',
				'after'       => '</div>',
				'link_before' => '<span>',
				'link_after'  => '</span>',
				'pagelink'    => '<span class="screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>%',
				'separator'   => '<span class="screen-reader-text">, </span>',
			) );

In addition, Read More typically shows on my pages as ‘Continue Reading ->’, but when I use query_posts, it shows ‘(more…) ->’ instead. Why is this so?

Here’s my query_posts code:

<?php
/*
Template Name: My Custom Page
*/
/**
 * The template for displaying pages
 *
 * This is the template that displays all pages by default.
 * Please note that this is the WordPress construct of pages and that
 * other "pages" on your WordPress site will use a different template.
 *
 * @package WordPress
 * @subpackage Twenty_Fifteen
 * @since Twenty Fifteen 1.0
 */

get_header(); ?>

	<div id="primary" class="content-area">
		<main id="main" class="site-main" role="main">

		<?php
query_posts( array( 'category__and' => array(23), 'posts_per_page' => 5, 'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1 ) ) );
			/* translators: %s: Name of current post */

		// Start the loop.
		while ( have_posts() ) : the_post();

			// Include the page content template.
			get_template_part( 'content', 'page' );

			// If comments are open or we have at least one comment, load up the comment template.
			if ( comments_open() || get_comments_number() ) :
				comments_template();
			endif;

		// End the loop.
		endwhile;

		?>

		</main><!-- .site-main -->

	</div><!-- .content-area -->

<?php get_footer(); ?>

Any help would be greatly appreciated!
