although it does rather remind me of a popular web forum software - it's the blue colour I think.
I'm an advocate of small font sizes for web sites - I hate seeing pages with all 10 or 11 point text, but I wonder if in your case it might be an idea to snitch the font up a point - at least until you have more content? It's not a big thing, but some of the text looks a little lost on an otherwise empty space.
Perhaps if you had a few more images it would improve the look, and tend to help hold readers on the pages?
These aren't major design flaws - you've done a good job - but maybe there's room for a little tweaking now, especially where images are concerned. A nice picture of the church itself on your homepage wouldn't go amiss, and one of the interior would be good too - especially if your church is an older building with stained glass etc.
