Though Martin sees the SDA as standing very near to the edge, in the end, he equates them with Arminian evangelicals. His reason for doing so is that in the official documents of the SDA, chief of which is Questions and Answers, they affirm key doctrines such as the inerrancy of scripture and salvation by grace alone through faith alone. Martin is convinced that the SDA affirms these things in an evangelical manner.

With regards to their overall theological standpoint, Martin quotes from the Adventists' official teaching as found in the book Questions on Doctrine (Washington, D.C.: Review and Herald Publishing ***ociation, 1957). In it, he showed that the Adventists are orthodox in their view of Scripture, their view of Christ, the completeness and suffuciency of the Atonement unto salvation, in their insistence of their belief in salvation by grace alone through faith alone. However, he also did highlight the unorthodox doctrines of soul-sleep, of annihilation as opposed to eternal suffering, and of the perculiar Adventist doctrines of the "Sanctuary" and of the "Investigative Judgment", the "Scapegoat teaching" and of course their strict Sabbaterianism.
What have you got that denies that?
