Every priest is pro-NFP. I bet a lot of them are confused by it, but I don't know any who are against it. Most just don't talk about it at all, probably for fear of starting a firestorm. It has become like the discipline that "dare not speak its name." Don't bring it up outside the confessional! On Bellarmine Forums, whenever someone raised the topic, everyone got all skittish and weird, like it was taboo. And in my readings on French websites I have not seen NFP come up even once -- it's like a non-issue.
Yeah, the sedes are the most pro-NFP of anyone. That is partly why last year I became a paranoid home-aloner. I thought that the sedes were the last of the Church and that even there the priests were trying to seduce people into mortal sins against chastity. That was the perfect circle that I thought the devil had drawn, the perfect net.
I'm kind of surprised the SSPV hasn't done away with NFP, since they took the dramatic step of rejecting Pius XII's Holy Week changes, the ones he made with Bugnini. From there it is a short step to also removing NFP. They are implicitly saying his disciplines can't be trusted.
I would not use it, though, and I'm probably not going to be married, so I am willing to just let this slide. I have exhausted myself on this topic. If the Church defines a discipline, it's done. If Pius XII were the Pope, NFP is a discipline. If he were not, it's a fake.
Until we know for sure, we can't expect those who accept Pius XII to teach against it. In a way, SSPV has the worst procedure, since they are cherry-picking what they want to follow when it comes to Pius XII. They are quite SSPX-like in regard to Pius XII! CMRI, though they make a big stink about defending NFP, which is hard to stomach, are actually being more consistent.
I don't blame the sedes for following the man they think is Pope. I just keep some reservations in my heart about Pius XII without any longer feeling the need to KNOW whether he was a Pope or an anti-Pope. I just know that, on the Day of Judgment, I think God will understand why I had reservations about him.
