Excerpts Instead of Whole Post

Hi @dgraham4,

To display excerpts of posts on home page instead of whole blog post change the following code in the below listed template files in your child theme of Twenty Fourteen theme.

Before Editing:

the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyfourteen' ) );

After Editing:

if (is_home() ) {
	the_excerpt();
} else {
	the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentyfourteen' ) );
}

Template files to be edited in the child theme:
content.php
content-video.php
content-quote.php
content-page.php
content-link.php
content-image.php
content-gallery.php
content-audio.php
content-aside.php

If you want using excerpt by change functions.php file because don’t want use too many file in child theme. You can use this code. This is the code i’m using in my blog.

function my_excerpts($content = false) {

// If is the home page, an archive, or search results
    if(is_home() || is_archive() || is_search()) :
        global $post;
    		$content = $post->post_excerpt;
   		$content = strip_shortcodes($content);
   		$content = str_replace(']]>', ']]>', $content);
    		$content = preg_replace("/<img[^>]+\>/i", "", $content);
    		$content = strip_tags($content, '<p>');

	// If an excerpt is set in the Optional Excerpt box
    if($content) :
        	$content = apply_filters('the_excerpt', $content);

	// If no excerpt is set
		else :
        		$content = $post->post_content;
        		$content = strip_shortcodes($content);
			$content = str_replace(']]>', ']]>', $content);
        		$content = preg_replace("/<img[^>]+\>/i", "", $content);
        		$content = strip_tags($content, '<p>');
        		$excerpt_length = 65;
        		$words = explode(' ', $content, $excerpt_length + 1);
				if(count($words) > $excerpt_length) :
        				array_pop($words);
       					array_push($words, '[...]');
        				$content = implode(' ', $words);
    				endif;
   			 $content = '<p>' . $content . '</p>';;

    	endif;
    endif;

// Make sure to return the content
	return $content;

}

// Add filter to the_content
	add_filter('the_content', 'my_excerpts');
