That sub nav in body is

That sub nav in body is "ok". It looks neat and the hover affect is neat. Takes a bit of time to figure out it's a menu of course, but I see no problems with it like it is.

OTHER NOTES:
I wasn't expecting to be taken to a forum for some of the links, nor a new tab either.

Also, the page you linked to is a little frustrating (resources_spiritual_couples.html).
I "eventually" figured out hovering over one of the four categories on the page showed text for that category, but at first I wondered what was happening when I was moving my mouse to the top navigation and text was appearing and changing seemingly randomly around the page.

If you space the four text blocks out a bit on the page, you can have them all static, and no need for them to show on hover.
I'd get rid of the smaller image you see on hover when the text is there, and just put the main image (prior to hovering) as a background on the text (with some opacity so the text is readable).

And all pages should be the same format, the homepage is very different, and green.

And you should fix some of the W3C errors you have. Mainly having no doctype.

Clean site though, the design and colours will certainly be liked by plenty of people.
