Let me begin by saying I hope I'm not opening up a can of worms here.
Of course, I'm sure most people here would agree that contraception is wrong and that if a couple has sufficient reason for avoiding pregnancy (e.g. health reasons, financial problems, etc.), then they may use Natural Family Planning (NFP). But of course, they have to be careful not to use NFP with a contraceptive mentality. Then again, unless their reason for using NFP is obviously frivolous, then whether or not a sufficient reason for it exists would have to be determined on a case-by-case basis.
Well, I've encountered Catholics who more or less believe that if you're not at death's door, or if you're not within a hair's breadth of being homeless, then you don't have sufficient reasons for using NFP. A lot of them also rashly assume that if you only have 1-3 kids or haven't gotten pregnant within a few months after getting married, then you must be contracepting or at least misusing NFP (I have a friend who actually assumed her 20-something sister was contracepting simply because she got married over a year ago and still isn't pregnant) . Worst of all, there are others (mostly extreme traditionalists) who actually believe that using NFP is "modernist" and in and of itself a mortal sin (because in their mind it can never be used without a contraceptive mentality) and think that one day the Church will declare it anathema. But isn't calling evil that which the Church allows heresy or at least close to it?
I guess I'm not so much wanting to discuss this topic as I am venting. I envy large families, but I get the impression that some Catholics almost make it a litmus test for how Catholic you are. Has anybody else experienced similar attitudes from fellow Catholics?
