We're taught to test with an open heart and mind, using the holy spirit as a testament, the Bible, judgment by one's words and deeds, from an objective as possible perspective, compassionately, using our own moral code- in our hearts, logic, discernment from reality, intellect, testimony of fellow believers, etc. It may not be based on a lot of materialistic principles, but it certainly doesn't preclude them from being used as testing.
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
