Hi igr,
Maybe you'll define the word "impose" to help me understand what you're telling us? You seem to worry that when I say that I believe that everyone ought to be Catholic, I want non-Catholics to be forced to become Catholics. That's not what I'm even implying. In other posts in other threads, I've already reminded everyone that Catholic Church teaches that it's immoral to make someone convert to Catholicism. So no, I don't want a Catholic police state where the police convert people at gunpoint. I believe that God obligates everyone to be Catholic. But you already know that forced conversions probably will be insincere. Suppose that a woman aims a machine gun at you and yells, "Tell me you love me, or I'll blow your brains out." Then you probably will obey to try to save your life, though I doubt that if you survive, you'll take an engagement ring from your pocket, kneel on one knee, and ask her to marry you.
Remember the difference between an obligation and whether someone deserves blame because someone or something prevents him from fulfilling it. Maybe I don't know that I ought to be Catholic, since I haven't even heard of the Catholic Church. Still, I can mean at least implicitly to do each thing God asks of me and therefore mean implicitly to become a Catholic. That's partly why I suggest that some fundamentalists would oversimplify if they said that Socrates, Plato, and Aristotle went to Hell because they hadn't accepted Christ. How can you blame them for failing to do that when you know that they lived and died before he incarnated? Ancient Jews learned from the Old Testament that they needed to expect the Messiah.
If you read the documents from the Council of Florence you'll know they teach that there's no salvation outside the Catholic Church. But in another thread, I've already explained the difference between being in the Church as a member of it and being in it as a nonmember of it. What's non-negotiable is that for anyone to go to Heaven, he must have God-given holiness in his soul when he dies. Anyone who dies without that holiness, even a lifelong practicing Catholic, goes to Hell. If I go there, it'll be only my fault. No one else will be to blame then. Lord Bertrand Russell said that if God asked him why he didn't believe in him, he would have replied, "Not enough evidence." God might have told him, "Bertrand, there was plenty of it. But you were too proud to look humbly for it. I don't grade people on their successes. I care about how sincerely and how hard they try." Remember the passage in Romans 2 where St. Paul writes about those who obey the natural moral law written in their hearts. They haven't learned the 10 commandments, but they still obey them because they "intuit" them or because they "know" them almost instinctively.
Yes, I know that many people disagree on the nature of personhood. But its nature is independent of what they believe about it. It's not relative to what anyone believes. That's partly why I think progressives who support abortion support it imprudently. I think it's best to say, "When in doubt, too much caution is better than too little caution." Too many progressives seem to say, "When in doubt, do anything you please." That would have been foolishly dangerous advice early last winter when Lake George had only begun to freeze. Had I wanted to ice fish then, the ice might have broken. Then after I fell into the frigid water, I might have frozen to death. Abortion supporters want to put babies on cracking ice when those supporters are sitting on something they'll float on if they ice breaks under them. They'll survive. The babies will die.
I respect people, but I don't respect any falsehood that anyone believes. How much I respect other people will depend on whether they earn my respect by showing their competence, their knowledge, their still, their sense of duty, their moral virtue, and more. As Archbishop Marcel Lefebvre teaches, "There are two kinds of human dignity, our inherent God-given dignity and the dignity we earn by behaving virtuously. Even if we'll have the inherent duty forever, we can lose the moral dignity through our own wrongdoing. The more evil I do, the less respect I deserve. If I'm culpably ignorant about the nature of personhood, that can decrease my moral dignity, too. Although I respect progressive people, I don't respect progressivism.
