Tag listings in Atahualpa 2.2

I administer www.lighthousealliance.org and I am having a problem with the archive listings for tags. When you click on a tag, the results show the content of the posts, but not the title of the blog post. I'm not sure what I did to eliminate the blog post title from showing, but can you assist me in putting it back in there? I can't figure out which template it is in. Here is an example of a tag archive listing, but no titles are showing: http://lighthousealliance.org/site/?tag=colossians
