@dan daly: I think you are arguing against a straw man here. I don’t read katie966 as saying that a couple doesn’t need to form their conscience or that the individual is the final arbiter of right and wrong. What I hear her saying is that, in this thread, based upon the information made available by the OP, one cannot tell if there is an issue regarding the seriousness of the reasons that the couple has discerned, and further, she was not seeking (name removed by moderator)ut on that aspect of the decision to use NFP.
That being said, it will still be up to the couple to discern what is grave, serious, just, or well-grounded reasons for postponing a pregnancy. The couple doesn’t get to decide the principle, but they are the ones who will do the application of the principle to their life.
FWIW, I do not think you or anyone else was judging the OP by stating some parameters for NFP use. I do not think you are stating them correctly, but as you said, we can discuss that. I also agree with your earlier position that while we cannot judge an individual or couple’s culpability, we can, and indeed must, judge whether actions are right or not.
Still further, are we not supposed to assume the best motivations about our fellows? It seems it is within reason to think the OP would want to finish school before beginning her family - - what if the husband dies and she must support the family? I am assuming it would be easier for her to get a job, and one capable of supporting a family, with her degree finished. She really hasn’t provided any info about their discernment process, and I think she specifically said she didn’t want to get into it. But in charity I think we must assume that she and her fiance’ did so and will continue to discern God’s will for them once they are, in fact, married. That may change a whole lot.
