Summary view of the posts in the SharePoint 2013 blog list

I have a blog site and I'm having fun with the page and, one way or another, the list of publications has changed and when I click on a publication, the one -It moves to another list. I've added a web part to the site's page from the Posts website content and now the page displays the message and the entire body of the message. I can not go back to displaying a list and when I click on a message, I see only the message and the body.
