Let's forget about Scofield's character, sketchy as it may be, and look at his agenda for producing the SRB in the first place.
1. To promote the critical Greek text of Westcott and Hort. At the time, the overwhelming Bible of choice was the KJV and the textus receptus on which it is based. He couldn't just produce a new Bible based on the critical text; people would have roundly rejected it. So what is he to do? He introduces the critical text in his notes, saying things like, "the oldest and best manuscripts" say such and such, thus softening people to the idea that the textus receptus and the KJV are flawed.
2. To promote Darby's dispensationalism in the US. Dispensationalism says that salvation is by different means in different ages. So under the Old Covenant salvation was by the law of Moses. But it doesn't take a whole lot to prove this idea ridiculous. Salvation is by faith and has always been by faith. If the law of Moses could save, it wouldn't have been replaced by something that truly could save.
"What shall we say then? That Gentiles, who did not pursue righteousness, have attained to righteousness, even the righteousness of faith; but Israel, pursuing the law of righteousness, has not attained to the law of righteousness. Why? Because they did not seek it by faith, but as it were, by the works of the law. For they stumbled at that stumbling stone." Romans 9:30-32
When I think of all the people who have bought into such an obvious deception it truly is bewildering.
