The Adventist leaders who met with Walter Martin presented a fuller description of mainstream Adventist theology, and described the more fundamentalist views as merely the beliefs of a few. (Le Roy Edwin Froom described them as the "lunatic fringe.") In addition to showing it had clearly moved from semi-arian views on the GodHead, the Adventists asserted that the belief that Christ took Adam's sinful nature after the fall and an incomplete atonement were not part of mainstream Adventist doctrine. Adventist historian George Knight felt it was not a complete picture as it could be, because a majority of Adventists prior to 1950 had held to these teachings concerning the nature of Christ and the atonement.
