So the Christians amongst us might demur. At the least you will admit that there are those who count faith as a virtue. — Banno
What is meant by Christian faith as being a virtue I suppose is a commitment to the truth of the teachings of Jesus Christ, which might just be a statement that the highest virtue is to believe in what is right and just and true. It might correlate to the first commandment, which is that one should have no other gods before God or perhaps the second forbidding idolotry.
But that's one of many ways "faith" might be defined, which is the question of this thread.
The Aristotlian virtues are are more specific, isolating particular aspects of a person worth fostering. It's the difficulty in translating precisely the language of Athens to the language of Jerusalem.
You mention misdefining god, or perhaps misunderstanding god's will. The obvious problem is the ubiquitous one that it is not entirely obvious to everyone what god's will is, and further there is no possibility of any objectively agreed standard here. While it might suit your narrative to claim terrorists "hijacked... certain terms and ideas for their evil purposes", this is not clear; on the face of it, al-Qaeda is a faith-based organisation. It doesn't, for example, recruit Catholics.
All this by way of showing that there is an element of special pleading in your suggestion that those who commit abominations in the name of faith are misusing the term. — Banno
The special pleading arises in supposing one ideology is for some reason immune from the problems of another and giving it a pass and suggesting the other is hopelessly dangerous. If we should examine each of the tens of thousands of bullets suspended in air, now in midflight, and place each under the microscope to decipher what anger is embeded in each of them, I'd suspect that remarkably few have thoughts of God and ancient theologies within them. Many I'm sure are filled with irrationality and raging hate caused by the mundane existence of individuals without compass, but I'd suspect a very good number, at least those that come in the largest flurries, are filled with secular interests being advanced under some guise of justice or righteousness. The hail of gunfire in Ukraine, for example, is a better example of mass destruction than 9/11. What intention do you suppose is impregnated in those bullets, the advancement of Christianity, Judaism, Islam? That doesn't seem right. Probably a drive for natural resources, the rebuilding of a fallen empire, or a a diversion from a failing economy? Secular interests that is.
I can't really see much of a difference from an atheistic perspective between the Good and God. God is rejected under this model as an outdated attempt to create a referrent for a concept that need not have one. This is to say that what I call the dictates of God you call the dictates of Good, yet you just find my language oddly clinging to the past in insisting upon an ontological existence for my holy being. Why speak of God when we can just speak of the Good without imposing upon ourselves the superflous baggage of the supernatural, right? But isn't it your view that what those two terms mean once you've purged the latter of its mystical nonsense is the exact same thing?
The point being we both cling to a moral realism, refusing to suggest that the stomping of babies is right if we happen to all agree it is. And we're willing to die perhaps to defend those babies from their stomping. Yet for some reason your declarations of righteousness and your fight to the death to protect those innocents isn't zealousness. It's heroism. You believe you can properly scream "Praise be the Good" as you save those infants and you will pose no danger because you are right in your views, unlike al-Qaeda when they screamed pretty much the same thing as they exacted not their heroism, but their terror.
This isn't to suggest we're all right, but just have different perspectives. I hold the opposite of that in fact. I agree you should fight to the death to save the babies from their stomping. I'll charge the stompers by your side. I'll just be screaming about God and you the Good.
My point is that if the danger is certainty towards one's ideology, then that exists whether your ideology is the promotion of the Good or of God. To allow that rule of dangerousness to only apply to God and not the Good is an example of special pleading, granting your brand of certainty immunity for no good reason.
