torahfamily on "Category listings"

I recently started using WordPress for a "Webzine" type section of a website: http://www.torahfamily.net/webzine/ .

I notice that on the category pages, the listings do not show up the same way they do on the home page. How can I make the listings on those category pages show up to the More tag (including the image at the top), like on the index page?
