Having spent about a dozen years on a site sponsored by a Reformed ministry, I think I understand why the question needs to be asked. As I said earlier, Protestant theology (especially justification by faith) is based primarily on the Pauline writings, and Paul is more concerned about the meaning of Messiah's death and resurrection in the context of Israel's story and Creation's metanarrative. Big picture guy. Only two references to Jesus's actual teaching. As an aside, I suspect he gave his travelling companion Dr. Luke the assignment of researching the details of Jesus's life and teaching. But I'll never be able to verify that this side of Kingdom come.
What I observed on that site was a mindset that, because Jesus intensified certain aspects of Torah ("You have heard it said.... but I say to you...", e.g. it's not enough to not bed a woman other than your wife, you can't even look at her with sexual desire; see Mount, comma, Sermon On), this was interpreted as Jesus making sure we understood that we cannot be justified by keeping Torah. This promotes the concept that says Jesus's teachings are irrelevant; the only thing that matters is the crucifixion. "Shaddup already about counting the cost and denying myself and get up on that cross and atone for my sins, please." Even the Resurrection was just a nice happy ending to the story, but not as important as the Atonement. Blecch. Yeah, I found people really think that way. Jesus's teachings were just another set of "Law" that we don't have to follow. We only have to have "faith", which usually meant "belief in the doctrine of justification by faith".
Me, learned to understand "faith" as "trust". Trust in a person, not a doctrine, though doctrine informs me about the One I must trust and what He wants from me. Relating to Jesus as a person, not just as an event in a metanarrative. Which makes Jesus's teachings important (even if I'm not doing a good job following them).
