Are There Any Protestant Churches That Are Starting to Recognize the Benefits of NFP?

I've heard that some Protestant churches are starting to recognize the benefits of NFP. I would say maybe one in every 50 couples involved, either the husband or the wife is of a different faith. So it's definitely growing from the standpoint of the couples using it. Well, that's what we're working towards. We don't know for certain if there's any churches ... willing to put a stake in the ground on it.
