    Nothing special in the .htaccess. Here it is:

    # BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

    What I found helped is when I did a print_r of all the rewrite rules in this function (function wp_insertMyRewriteRules($rules)).
    Insert
    echo "<pre>".print_r($rules, true)."</pre>";

    That will help you to debug all the rewrite rules that are being added.

    Also, the order of the rewrite rules being added is important.
    E.g.

    $newrules['sermons/scripture/([^/]+)/chapter/?([0-9]{1,})/page/?([0-9]{1,})/?$'] = 'index.php?pagename=sermons/scripture&book=$matches[1]&chapter=$matches[2]&paged=$matches[3]';
$newrules['sermons/scripture/([^/]+)/chapter/?([0-9]{1,})/?$'] = 'index.php?pagename=sermons/scripture&book=$matches[1]&chapter=$matches[2]';
$newrules['sermons/scripture/([^/]+)/?$'] = 'index.php?pagename=sermons/scripture&book=$matches[1]';

    It will try to match the first rule and if it doesn’t match, then continue.

    Those were the difficult gotchas…

    Good luck,

    Leonard

    I solved it. Here’s the final solution.

    In functions.php

    add_filter('rewrite_rules_array','wp_insertMyRewriteRules');
add_filter('query_vars','wp_insertMyRewriteQueryVars');
add_filter('init','flushRules');

// Remember to flush_rules() when adding rules
function flushRules(){
	global $wp_rewrite;
   	$wp_rewrite->flush_rules();
}

// Adding a new rule
function wp_insertMyRewriteRules($rules)
{
	$newrules = array();
	$newrules['sermons/scripture/(.+)'] = 'index.php?pagename=sermons/scripture&book=$matches[1]';
	$finalrules = $newrules + $rules;
        return $finalrules;
}

// Adding the var so that WP recognizes it
function wp_insertMyRewriteQueryVars($vars)
{
    array_push($vars, 'book');
    return $vars;
}

//Stop wordpress from redirecting
remove_filter('template_redirect', 'redirect_canonical');

    In your page theme:

    $book = urldecode($wp_query->query_vars['book']);
