The problem here is that many people who hold to tradition don't even know history or the Bible:
(Rom 2:4 NIV) Or do you show contempt for the riches of his kindness, tolerance and patience, not realizing that God's kindness leads you toward repentance?
You don't know these things because you don't look into these things. You don't look into these things because you think you already know the truth. You don't question what you think you know. And that sadly is the real difference between Progressive SDA's and Traditional SDA's, Progressive still question and search while Traditional SDA's firmly believe that they already have the truth.
In the current Adventist culture there is one group that really uses the moral influence theory and they get it mostly from Ellen White, they don't call it that because they add other things to it so they call it the Larger View. But they totally reject the Penal concept of atonement as well they should. It is totally unbiblical but it is traditional. Not a tradition for the first 1100 years of Christianity but sometime after the Satisfaction Theory of the Atonement became popular the penal theory developed out of the Satisfaction theory.
Now I know these things because I studied them. Study is something many Traditional SDA's no longer do. Oh they will study to the Bible to find ways to use texts to fit their preconceived ideas so they can as Woob did above quote a text and say Paul was totally against something that really the texts does not say but tradition and words used like propitiation please their preconceived ideas. Modern Bibles would says an "atoning sacrifice" but since that fits very well within the idea of the moral influence the Penal theorist traditionalist use the King James wording because it carries the idea that the sacrifice was to please God rather then to affect man. But the man was the problem not God, God was the one reaching out to man and that is what an atoning sacrifice is.
