css, I cannot set font like another site in Safari (mac)

Ok so I have built this site: http://boardersforchrist.com/new/ and the owner wanted the footer text(font) to be the same开发者_Python百科 as the footer text on http://desiringgod.com. The font in the lists on desiringgod looks thin compared to boardersforchrist.com/new/

This problem only appears to happen in Safari on a mac. I have used Web Inspect and cannot see a difference. Can anyone take 5 and see where my issue is? This is rediculous... I have been at it for days. The original html and css came from a theme and the theme is probably got something affecting it...

thanks so much

on the bfc website, headings such as "Twitter" aren't really headings (<h2> elements) at all, but rather a <li class="footer_page_title">, which is styled with font-weight: normal; instead of bold.

Hope that helps.
