Hide Page Title

I want to hide my page titles that appear in the body of the actual pages I create as it is somewhat reduntant.

I found in blogs-mu theme parent folder the original page.php on line 14
<h1 class="post-title"><?php the_title(); ?></h1>

and commented out like this
<h1 class="post-title"><? /* php the_title(); */ ?></h1>

It worked just fine. However I want to add that code to my functions.php instead.

I tried a few things and they all failed.
