Justification by faith and intellect?

There are some today, in reformed circles, that are saying that a misunderstanding of the doctrine of justification by faith alone (sola fide) is a sign of apostasy. In other words, you are not justified by faith alone, you are justified by properly stating the proposition of justification by faith alone. We are justified by faith alone, not by a perfect understanding of justification by faith alone. We are saved by grace through faith, and not through a propositional understanding of grace through faith. It's kind of ironic that some, by fighting fiercely to protect the doctrine of sola fide, are actually denying it.

Doug Wilson explains, "We are not saved by works, and this includes our intellectual and doctrinal works. There are people who would do poorly on the "justification by faith alone" portion of their theology exam who are nonetheless saved people. And there are people who would ace that section who are damned. We are not saved by works. Not by willing, not by running, not by smiling, not by thinking, not by catechizing, not by affirming, not by Westminster-confessing, nada, zilch, zip. All our works have corruptions in them and are received by God because they are presented to Him in the perfections of Jesus. This includes our doctrinal works, which are frequently all screwed up. We sin daily in thought, word, and deed."
