Faith is an abstraction, and like all abstractions, has no substance. And think about the phrase "evidence of things not seen." Evidence is what *IS* seen, what is evident. Faith sidesteps evidence and substance and goes directly to belief.
I think it's the believers who have trouble understanding what faith is. It is one of two methods for coming to beliefs, the one that doesn't use evidence. Thus, we have can hold both justified and unjustified beliefs. Faith is the latter. If you believe something is true and came to that belief without applying valid reasoning to evidence (justified belief), whatever other method you used, the belief is unjustified, making it a faith-based belief.
I would say that if one has a different understanding of what faith is and what its place is in epistemology, that it he that doesn't have a correct definition of faith. Notice that I am not referring to a different word with the same spelling and pronunciation, which means justified belief, as in faith borne of experience - faith in a wife, or in a car starting, or any other justified belief based on experience and evidence. The beliefs are justified if they include the idea that what is expected might not be the case - the wife might be cheating, and the car not start next time, but the belief that such things are the case is not based only in the will to believe.
Religion glorifies faith and where helpful, demeans reason for good reason - its dicta can only be believed by faith. And we see poetry like the scripture you cited from Hebrews. And we see it attempt to make faith more substantial than just a hope believed, it has substance and evidence we are told, even though it has neither - a kind of unwitting not to empiricism and the idea that substance and evidence can make beliefs sound.
With humanism, it's the other way around. Reason is the virtue and faith the logical error (non sequitur).
I was just watching the January 6th committee. Over and over we see the conflict between those who required evidence to believe that the election was stolen such as Barr, Cippolone, and Herschmann, and those who didn't, who kept insisting they had it and promising to provide it such as Giuliani, Powell, and Flynn, but couldn't and thus never did. One group was willing to believe by faith, the other comprised empiricists.
I guess that Giuliani, Powell, and Flynn were referring to the evidence of things hoped for and the substance of things not seen, which, of course, meant no substance or evidence at all. These two groups nicely represent and contrast the traditions of religion and empiricism. Faith was hardly a virtue there, was it? Nor did it serve the January 6th insurrectionists, whose only "evidence" was Trump's word. They had faith in him.
