All I'm saying is that the Saints would have rather died than willingly commit a sin. We aren't in a situation (yet) where it is costing us our lives to not have the jab. I'll read the article.
That's not the point. What's at issue is whether it is a sin. Granted, if it's a sin, you can't do it regardless of circuмstances.
It's one thing to die yourself; it's another thing to cause someone else to die. "Yep, that person you're unjustly seeking out to murder is in my bedroom; I'll go get him for you." You don't think THAT would be a sin?
If some random person were to ask another person who just came out of the Confessional, "Did you confess the sin of fornication?" That person has absolutely no right to that information. Let's say you prevaricate because you don't want to lie, then the person might assume that you did. So sometimes a mere mental reservation actually gives away a truth that someone doesn't have a right to know. And playing games with mental reservations seems childish and juvenile.
I have a lot of sympathy with the position that, given that the nature of language is to manifest your mind to SOMEONE ELSE, if that someone else has no right to the information, it's not a lie to just say "No." In other words, with the premise "AS FAR AS YOU'RE CONCERNED". I tend to agree with that position. But if a parent asks a child, "Did you break this window?" since the parent has a right to know, THEN it would be a lie. In fact, even the moralists who agree with mental reservation say that a mental reservation would be a sin IN THAT CASE. Why? Because there's the "right to know" component. So why does that "right to know" component not extent to a materially false statement.
So if someone were to ask, "Is that [falsely accused] criminal in your house?" I don't see any sin in saying, "No, that person is not in my house." While theology has made much of formal vs. material in every other field of theology, it's ignored when it comes to lying. This would be a case where the proposition is materially false but it's not formally a lie ... when you understand that the formality of the lie is not in the materially false proposition but in the deception of someone who has a right to know something.
