There are some NFP topics in Family Life that made me wonder something. There is currently a debate over what is considered a valid “serious” reason for the use of NFP. It seems to me that the consensus in that topic is that NFP, while allowed, is not required for the ordinary Catholic married couple. But what if the situation isn’t ordinary? For example, one post mentioned the fictional situation of Melanie Wilkes in Gone With The Wind, who is told a future pregnancy could kill her, but gets pregnant anyway, and does indeed die. Did Melanie (and husband Ashley) commit a sin? What if a woman is taking a medication that can cause birth defects? Or what if the family is homeless, on welfare, etc? Or a situation like that of Andrea Yates? Did she and her husband sin by continuing to have children? But then you could argue that most families in Third World countries are sinning if they don’t use NFP, and that seems a little absurd. But then on the other hand, just because a lot of people are doing something (like masturbating) that doesn’t make it any less a sin.
So, would anyone argue that there are cases where a couple sinned by not using NFP, or not abstaining altogether?
