Nevermind, I just answered my own question. For those who may be wishing to do the same, in content.php replace:
<?php if ( is_search() ) : ?>
<div class="entry-summary">
<?php the_excerpt(); ?>
</div><!-- .entry-summary -->
<?php else : ?>
<div class="entry-content">
<?php
the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentyfourteen' ) );
wp_link_pages( array(
'before' => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfourteen' ) . '</span>',
'after' => '</div>',
'link_before' => '<span>',
'link_after' => '</span>',
) );
?>
</div><!-- .entry-content -->
<?php endif; ?>
with:
<?php if ( is_single() ) : // Only display full content for Single page ?>
<div class="entry-content">
<?php
the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentyfourteen' ) );
wp_link_pages( array(
'before' => '<div class="page-links"><span class="page-links-title">' . __( 'Pages:', 'twentyfourteen' ) . '</span>',
'after' => '</div>',
'link_before' => '<span>',
'link_after' => '</span>',
) );
?>
</div><!-- .entry-content -->
<?php else : ?>
<div class="entry-summary">
<?php the_excerpt(); ?>
</div><!-- .entry-summary -->
<?php endif; ?>
