Because sexual sins are the grave sins (mortal sins if the three conditions are fulfilled) that cause the most problems for the most people, and threaten to drag the most people into hell, at least in our cultureThank you for your reply. But why so interested in others’ sexual morals? Why not other sins?
Also, they are the sins that the modern world largely refuses to acknowledge — evangelical Christians stand with Catholics in condemning premarital and extramarital sex as well as pornography, Mormons and Jehovah’s Witnesses oppose self-pleasure, and Orthodox Jewish practice (Hasidic et al) largely parallels traditional Catholic morality, but the Catholic Church stands alone, pretty much, in condemning contraception as an intrinsic moral evil.
Is there any other category of grave/mortal sin that gives Catholics any more difficulties, than sexual sins? To ask the question is to answer it.
Ours just happens to be a culture where people insist on sexual freedom. Other cultures may have other challenges and “pet sins”. For instance, there is a small subculture in this country where some — not all — of its members travel throughout the country, swindling unsuspecting people with shoddy labor, and even outright stealing from them. For these people, stealing and dishonesty in business are their “pet sins”. There is a tragic swath of mountain country in the Eastern United States where prescription drug abuse, as well as illegal drugs (homemade methamphetamines and illicit marijuana), are very common, and the people engaged in this trade either see nothing wrong with it, or realize it is sinful but do it anyway, out of desperation or just plain greed. In many cultures throughout the world, “honor killings” are just accepted as the way their societies work. And so on. Every culture has its issues.
It seems that way. I have reflected back over 40+ years of being Catholic, and I have never heard of a non-Catholic wife with a Catholic husband agreeing to use NFP for the entire duration of their childbearing years. I’m sure it happens, I certainly hope it happens, but I’ve never heard of it.Can’t speak from personal experience but we’ve noticed that it’s more common for a Catholic wife to say “we’re using NFP” than a non-Catholic wife with a Catholic husband.
