From the post Progressive Christianity and the Bible
There definitely is uncertainty inherent in the progressive Christian outlook. But the view that it is a bad thing is based on a faulty understanding of “faith.” In modern English, that word has come to mean “believing incredible claims in spite of lack of evidence or even evidence to the contrary.” Historically, even in English the term meant something different, and more importantly, the Greek word usually translated “faith” in the New Testament has overtones not only of faithfulness but also of trust. Trusting is not what you do when you are certain you are right. It is what you do when you know you could be wrong. Being willing to live with uncertainty can be an expression of faith in God rather than its antithesis.
