Pretty much. When you actually come close to addressing that then let me know. What you wrote in no way addressed this. And to attempt the reframing of the situation in the way you are doing is irrational. IIHS is a made up concept from what I can see (feel free to come up with something rational suggesting otherwise that isn’t as circular as your last post).
Your following comments show that you have deeply misunderstood the connection between what you said and what I said. So I'll try again.
Here's your claim:
Christian belief in the virgin birth and the resurrection is irrational because there isn't much evidence for these beliefs and what we know from biology suggests, nay screams out, that such things don't (can't?) happen.
My argument is that Christians,
if Christianity is true, have rational sources for belief that don't appeal to physical (or even literary) evidence. So the lack of evidence is not relevant to whether the Christian is rational in holding these beliefs.
Faith (Acquinas' internal instigation of the Holy Spirit or IIHS) is part of that. Thus, faith is a rational process that is aimed at furnishing us with true beliefs about God and, at times, about history. If I know something by this process, and it conflicts with science, so much the worse for science. Or perhaps more charitably, science describes what is usually the case, but by IIHS I can learn about very occasional exceptions, such as virgin birth and resurrection.
In other words, I'm claiming (Christianity claims) that Christians have access to information other than history and logic: faith (IIHS).
Faith is a rational process, part of our cognitive establishment designed to issue in true beliefs, that puts us in touch with truths such as the virgin birth and the resurrection. (More accurately, the bible or preaching puts us in touch with these truths, and faith -- IIHS -- reliably provides the true conviction that these things are in fact so.) All I say about this is that it's possible for these Christian beliefs to be warranted (or as we are saying in this thread, rational)
if there is such a process.
Therefore, to say that Christianity is irrational is tantamount to saying that it is untrue.
Does this bury the problem? Not at all. It simply shows that Christian beliefs can have warrant apart from evidence. So the Christian need not be concerned that the evidence for the virgin birth or the resurrection isn't very strong (once IIHS is taken out of the equation). Christians might admit that but also say that they have another source of warrant for their beliefs, and therefore they are rational in so believing. To contradict them, the skeptic has to show that Christianity is actually false.
Is it irrational to appeal to IIHS? It's hard to see why. You have asserted that it is, but you haven't argued for it. IIHS is simply part of the Christian theological package. It's a claim about how we can know some of what we think we know. What's wrong with it?
No it doesn’t. The motivation has no bearing on the truth value. But good luck with the irrelevant tangent you decided to attack rather than the central point.
That's not what I said. I said that one's attitude may affect whether one accurately perceives the truth. Take a more mundane example. A man may refuse to heed his friend's warnings about the infidelities of his fiance. The friend patiently lays out the evidence. The friend is normally trustworthy. He has never been known to lie. Yet the man, in the throes of love, disregards this reliable testimony and rejects the evidence. Thus we can see how an emotion might make someone refuse to see the truth. And in fact, isn't this what skeptics and believers frequently say to each other? "You'd believe me if it weren't for <insert emotion that clouds judgment here>."
In this case then you would have to provide me with a defeater for my claimed godliness. This line of reasoning is irrational and I can only wish you good luck with it.
If that were your serious claim, then yes, I'd have to provide you a defeater if I wished to disabuse you of the belief.
