Looks like that was a Premium theme? (Pricey, yikes!)
I'm thinking its going to be tough to troubleshoot your challenges since I can't download and install it to see what's happening behind the scenes. Not the same to just look at your source code. :*(
I've looked their the theme company's website, specifically at their demo site for the Church lady theme. Oops, sorry ;) the Church Theme :)
As well as looking through your site. This is just a slightly educated guess on my part, but I think the theme doesn't provide for "posts" (not "pages") to be displayed on a 2 column page.
Now you "could" get into your theme templates and hack something together but unless you are VERY comfy doing that I might advise steering clear.
For nearly $60 I would think you should certainly be getting support from the theme creator :(
I know this doesn't help much, however, I think it will be hard for us to solve this problem. Of course I could be wrong. I often am :|
