Christian, Muslim, Hindu Buddhist, Jew etc, are they not all the same? Don't they all believe their religion is the repository of the path to the good and that by following that teaching and perhaps that teaching alone one can attain to that goodness oneself? Do they all not ask one to have faith, that is to believe the truth of the teaching, and not some personal path you invent for yourself, whatever notions about the good you may have started out with? Isn't that form of submission, the surrender of personal judgment called faith? Isn't faith then a simple submission to a goodness that may transcend human comprehension? Isn't faith a trust in the existence of good? So why would anyone care what name they put to their faith when the faithful of each believe the same thing? The truly faithful then, are they not all the same?
Why would anyone argue one religion over another, then, unless they lack faith, unless they don't really believe and are incapable of trust in the good.
