Sorry to go off tangent, but the problem wth aggressive believers like that is that their faith has no doubt. They are certain they are right and that is why they are wrong. But real faith is trust, not certainty. In real faith doubt still exists.
“Doubt is but another element of faith.” (St. Augustine)
“Doubt is not the opposite of faith; it is an element of faith.”
(Paul Tillich)
“Don’t expect faith to clear things up for you. It is trust, not
certainty.” (Flannery O’Connor)
“You call for faith: I show you doubt, to prove that faith exists. The more of doubt, the stronger faith, I say, If faith o’ercomes doubt.” (Robert Browning)
