A merciful God doesn't provide loopholes to the oppressor. Which is what you're suggesting. The "wonder of faith" that allows people to label, and discriminate, and oppress is, indeed, a "loophole" of the facts that is used by the "faithful" to continue to label, and discriminate, and oppress. Whether you like it or not, the (embarrassingly few) references to the "evils of homosexuality" are troublesome for the biblical literalist when weighed against what we now know about sociology, human sexuality, and human psychological health. The "wonder of faith" certainly doesn't magically make that juxtaposition disappear. Happily, critically-thinking, educated, liberal Christians aren't held to this ridiculous, arbitrary standard of biblical "inerrancy," so they don't have to justify treating those who identify as homosexual as real and equal human beings, who are perfectly healthy and eligible for the same rights as everyone else. Only the fundamentalist has to move goal posts and twist meanings, and must justify her or his gross inhospitality to the "stranger."
