yes - faith is also required to use crosses against vampires - if you don't have it, the cross won't work. I wonder if vampires made it onto the ark? And why don't they evolve too?
I can imagine a strain that only attacks fruits, or bugs...
There is no such thing as faith without an object. Nor can there be faith without facts and propositions. "Blind" faith is another matter. As far as I know everyone puts their faith in many things from moment to moment, day to day.
Blind faith says, "the earth is billions of years old" when there is no experience or testing to back it up. Ordinary faith believes the earth and natural laws will behave with the same consistency tomorrow as they did yesterday.
Faith with itself as an object is empty and absurd.
