You know, when I went to get married and was reading about NFP and all its benefits etc, I too was confused with some of the “advertising” out there, we had started off deciding we were not going to use NFP (or anything), but it almost seemed as if we were going to miss out on so many important things if we didn’t use NFP, some people even suggesting we were not going to be active participants in the creation of life (lol, I should have been able to figure that one out on my own). Anyways, after speaking with a few great priests and the (awesome) brother that did our pre-marriage prep, I realized although there are great things that can come out of NFP, and it can help develop many virtues etc, these virtues can be attained in a healthy marriage that does not decide to “regulate” its births too, and a couple should not use NFP to avoid if they do not have the right reasons, in other words, it could also be sinful, the very thing that was supposed to be the ideal for every marriage (according to some). Now, I am not trying to knock on NFP, I am very thankful it is there because a situation may arise where dh and I have to avoid receiving blessings for a short or long period of time, and being able to use NFP to avoid rather than having to abstain indefinitely will be a blessing… hard work, discipline and all, but I had to realize that NFP is just that, a tool available for couples when they need it, one that when done correctly can also serve as a tool to strengthen some virtues and has other positive supernatural repercussions. It doesn’t matter what people say to try to help couples stop using ABC (which shouldn’t even be part of the picture to begin with, bears not weight on the value of NFP), it doesn’t matter what others are using to “advertise” NFP, I am thankful and appreciative that the Church has looked into the tough situation of couples that have serious reasons to avoid, but would have to miss out on the beauty of the sacramental marital embrace by abstaining completely if it weren’t for NFP. I can ignore the comments (sometimes erroneus) that people use trying to help their brothers and sisters get away from ABC (which is intrinsically evil, and they are doing well in trying to help them). I too think it is a bad idea to idealize NFP since the reason NFP is good is not because it is the “ideal” but because it is a moral way to regulate births when needed, and in being a moral way to deal with a problem, it also has positive moral repercussions, but if one idealizes it from an earthly point of view, and a couple does not find it meets their expectations, they can become disillusioned… NFP, although it does have good “earthly” attributes, is mainly good because of the supernatural aspect. If a couple does not understand that part well, it makes it a lot harder on them, although, yes, NFP is hard on its own, understanding it or not, but the more we see the supernatural value of things on earth, the easier it is to cope with them (not saying it is easy, just easier).
Lol, sorry to ramble on, but as someone who was also confused at one point because of the “advertising”, I just thought I would chime in :D.
ETA: I do agree with the approach of helping people that are using ABC switch over to NFP, as ABC to avoid pregnancy is always intrinsically evil regarldess of the reasons it is being used, but the way we approach is what we have to be careful with.
