Not familiar with Coral Ridge, but it's always surprised me that Ray & Kirk associate with TBN.
TBN is one of the biggest, if not the biggest kid on the block when it comes to (non Catholic) Christian programming. While I agree with the sentiment (I confess to having winced through TBN, to catch them and a few others once or twice myself), TBN is probably the quickest, safest, most established route for gaining a national religious television audience. And given their reputation for quality and discriminating tastes, I imagine they also charge reasonable airtime fees.
Just because you have a show on their network does not mean that you subscribe to the theology of the owners. My own church has a program on TBN (I usually don't watch it because I've heard all the sermons before). So what? A lot of Churches purchase time from CBSNBCABC affiliates. Are they any better than the Crouches?
